Frank Delporte announced a new release of MelodyMatrix : “Looking at MIDI music is now possible in multiple languages with release 1.1.0 of MelodyMatrix. And the website got totally reworked , is more flashy now, and also available in multiple languages. More updates coming soon…”
Blog post by Frank Delporte related to the release of MelodyMatrix 1.1.0 last week: “Last week was busy for MelodyMatrix . The website got rebuilt from the ground up, and the app itself got a solid release with a handful of new features.”
RGiskard7 announced Jylos 2.4.6 , the local-first knowledge management app with Markdown notes: “The app is much more polished: better Canvas support, cleaner themes, improved PDFs, vault switching without restart, GitHub update checks and smoother Markdown workflows. " Check the release notes on GitHub .
nlisker shared on Reddit : jextractGUI - A JavaFX GUI wrapper for the jextract tool. “It’s written in JavaFX and embeds jextract (and its libclang) within it. Since jextract is in early-access, newer versions broke it and I needed to do some rewrites since I first conjured it a couple of years ago. It’s now aligned with the current latest build - 25-jextract+2-4 (2025/11/25). " Project is available on GitHub .

Games

Nice Application 1 (Udit) submitted Daybreak Protocol to the DEV June Solstice Game Jam : “A short, replayable JavaFX code-breaking game where daylight is both the player’s timer and reward. Repair six symbolic Bombe relays by solving puzzles based on Caesar shifts, XOR logic, run-length encoding, parity bits, contradiction elimination, and binary search. Every wrong answer visibly pushes the sun toward the horizon. The game celebrates Alan Turing’s legacy by presenting algorithms as creative tools. " Source code on GitHub .

Components, Libraries, Tools

Frank Delporte blogged about a big rendering upgrade for Lottie4J : “My goal was to make the JavaFX output match the official LottieFiles web player as closely as possible, pixel for pixel. … After the improvements, most of the animations used in the test now hit 99.5%+ similarity with the reference!”
Frank Delporte released Lottie4J v1.2.5 with many rendering accuracy fixes: “The JavaFX animations are now more closely aligned with the official LottieFiles web player. Most test files reach the 99,5% similarity goal. " All info on the website .
Dirk Lemmermann is reworking/improving his libraries : “I fixed a major bug in HiddenSidesPane that prevented proper layout passes for children nodes. To get the fix start using the implementation found in GemsFX, do not use the one in ControlsFX. (btw: I moved several of my ControlsFX contributions to GemsFX in order to speed up development.)”
rrangelox published GrooveFX : Dynamic FXML for JavaFX, declarative iteration, conditionals and branching. “I’m releasing GrooveFX, a small library that extends JavaFX FXML with declarative control structures: iteration, conditional rendering, and multi‑case branching directly inside FXML. The idea is simple: FXML is powerful but static — GrooveFX adds flow without replacing it and without introducing a DSL. " Check the Codeberg repository .
Frank Delporte announced a new JavaFX library: Sheetmusic4J, an open-source Java library that parses MusicXML into Java objects and renders them as native JavaFX music sheet views. No WebView, no browser engine, no JavaScript bridge.
- Website: sheetmusic4j.com
- Source code: github.com/sheetmusic4j/sheetmusic4j
- Blog post and video with more info about the project on webtechie.be .
Frank Delporte blogged about Sheetmusic4J 0.0.3 : “I released 0.0.1 as an open question: does anyone want a native Java(FX) sheet music library? Multiple LinkedIn comments, and some are answered now with support for ABC notation and Guitar Pro. Plus a big round of engraving improvements.”
Eliezer Assunção De Paulo announced Megalodonte , a small reactive UI framework on top of JavaFX. “I’ve been building JavaFX desktop apps for a while and got tired of the usual boilerplate (manual listeners, imperative styling, no real component model), so I built Megalodonte: a thin reactive layer on top of JavaFX — React-ish component composition, State /ComputedState for reactivity, and a Props/Theme system so styling isn’t scattered setStyle() calls everywhere. " The project is available on GitHub .
Dirk Lemmermann shared : “GemsFX 4.3.2 is out now with fixes for the PopOver control, with i18n resource bundles, and accessibility support. I was always too lazy for the last two things but with AI that has become a no-brainer … literally …. “no brain required”. " Check the project on GitHub .

Podcasts, Videos, Books

Helal Anwar published a new video with the progress he made in his student management app .

Introducing Sheetmusic4J, a Java(FX) Library to Render and Interact with Sheet Music

Thu, 30 Jul 2026 07:28:00 +0000

I’m building MelodyMatrix with my son, an application to look at and play along with music. The app already shows a song in different views: falling blocks, chords, guitar views, and many more. Now we want a Learn section, a view that helps someone practice piano by following the actual sheet music while it plays.

A static PDF of the sheet doesn’t work for that. Great PDF viewer components exist for JavaFX, but a PDF has no connection to what’s playing. Nothing highlights the current note, nothing marks the current position in the song. I looked for a JavaFX library that renders sheet music and lets code interact with it: jump to a position, highlight a note, follow playback. I couldn’t find one, so I built it.

Closing the Visual Gap Between the Official Lottie Webplayer and Lottie4J

Tue, 07 Jul 2026 08:25:55 +0000

A Lottie library is only as good as its output looks. If an animation renders differently in Lottie4J than it does in the official web player, that’s a bug, even when no exception is thrown and the code looks correct.

Within the fxfileviewer, there is an app to visually compare the result of the JavaFX player and a webview using the official JavaScript player. Problem is that I was using the JavaFX Web component for this and this doesn’t fully support the latest/best version of this player. Based on this app for manual checks, I also created a unit test which is able to loop over a set of files and compare the differences to make sure changes in the code don’t break the existing renderer. But I kept struggling with the same test file interactive_mood_selector_ui.json which didn’t render correctly, both in the JavaFX view and my web-based view to compare it with.

Core

Message by Johan Vos : “I’ve spent most of today (and the past few days) on JavaFX 17/21/25 LTS. It’s a lot of work, but almost a pleasure because the tools/procedures are so clear. Skara is extremely helpful with backports. And it’s deterministic. JavaFX is very well maintained.”
From the dev mailinglist: Michael Strauß integrated JDK-8385459 in PR #2177 : Animations should respect reducedMotion preference: “Several JavaFX controls use animations to convey state changes, but none respected the reducedMotion accessibility preference. This change makes TableRowSkinBase, TitledPaneSkin, TabPaneSkin, PaginationSkin, and Charts honor Scene.Preferences.reducedMotion.”
Apparently, the JFX Adopters Meeting 2026 led to a pull request by Marius Hanl in the OpenJFX repository: 8386663: Stylesheet/StyleClass list should be lazily initialized . Thanks, Oliver Kopp for sharing this info .

Applications

Video by Ethan Lee : “I Built My Own Agentic AI Browser Turtlebrowse now with Java CEF, Swing, and embedded JavaFX components. Go watch it on YouTube .”
Ethan Lee released Turtlebrowse v1.1.1 , the open-source browser built to be agentic: “This brings features like a multi-process architecture and custom profiles. It also brings patches for internal API errors. It uses Gemma4 under the hood, perfect for everyday tasks. Get it at turtlebrowse.ingstudios.dev !”
Gufran Thakur created a simple, minimal Canvas Application in JavaFX : “After like a year finally getting back to JavaFX, decided to make an excalidraw inspired app for fun. It’s a very minimal canvas app with basic features. Source code is on ExplainFX . Features: Drawing, Create Squares and Circles, Text, Vary stroke size/font size,… Please let me know if you have any questions!”
Max Xiong continuous his “Building In Public” journey for his DataCollie application. Follow him on Bluesky for regular updates and screenshots : “Tonight I implemented the custom UI styling for Project context menu items.”
Found on Reddit, by xdsswar : “Dropping a small PDF viewer for you guys (JavaFX + native PDFium). It’s done on native PDFium via Java’s FFM API (no PDFBox, no AWT). Has zoom, text selection, search, thumbnails, the usual, would love some feedback. Repo link .”
By RGiskard7 : “I built Jylos, a local-first open-source knowledge management app using Java and JavaFX. It started as a personal project to explore desktop application architecture, JavaFX, Markdown processing and software design. Over time it evolved into a complete application with: Markdown notes with live preview, Wiki-links and backlinks, Interactive knowledge graph,… Everything is stored locally. No accounts, no cloud backend and no telemetry. The project is open source under the MIT license and binaries are available for Windows, Linux and macOS. I’d really appreciate any feedback, especially from JavaFX developers.”
Mechanical-pasta shared his “First JavaFx Application” on Reddit : “I tried JavaFx, and, as a support project to learn the language, I’ve decided to build my own MineSweeper but with some differences. You can find it here if you’re interested .”
In the Links Of The Week of 2026-05-29 , we shared “DiskSpace”, a cross-platform disk space visualizer by Marcus Hirt . In the blog post Using GraalVM, JavaFX and a Clanker to Build a Cross Platform Desktop App , he shares a lot of background information about the project, the architecture, and the build process.

Components, Libraries, Tools

Striking_Creme864 shared a video on Reddit : “Live property editing for JavaFX nodes in DevTools. When building JavaFX applications, we often need not only to inspect a node’s properties, but also tweak them to see how they behave. Restarting the app every time to test small changes quickly becomes a major time sink. So we added live property editing directly to the DevTools in our platform (TabShell). The property editor supports three simple forms: basic values, enums, and Insets, but this made UI debugging and iteration much faster.”
Dirk Lemmermann shared screenshots of the new StageStyle.EXTENDED: “I recently updated the FlexGanttFX showcase application to use the new HeaderBar component and StageStyle.EXTENDED type. This results in a very clean and professional looking UI. "
- You can also try it online at demos.jpro.one/flexganttfx-showcase.html or install locally via jdeploy .
Frank Delporte released Lottie4J 1.2.4 : “Fixed Lottie arc rendering: constrained the easing solver to prevent bezier curve divergence. Added bisection fallback for flat-point curves. Fixed full-circle trim path flickering caused by floating-point precision loss in offset wrapping. Fixed border rendering error. Added Pi4J test file. " Available on Maven Central .
FXML/2 for JavaFX : IntelliJ IDE plugin for the FXML/2 markup format , supporting syntax highlighting, folding, formatting, EditorConfig-aware indentation, tag and attribute resolution, code completion, and navigation to JavaFX classes. Presented as “FXML 2.0: Write Markup, Ship Bytecode” by Michael Strauß at the JFX Adopters Meeting .
Jonathan S. Fisher is working on DiFX, a CDI / Dependency Injection For JavaFX : “The goal is to have CDI backed beans and events inside JavaFx Desktop Applications. I could use a few eyes/ideas before I cut an initial release and stabilize the API.”
techsenger published ShellFX on GitHub : a platform for building JavaFX applications using an extended MVP pattern. Part of the growing Techsenger JavaFX library ecosystem (alongside CEFFX, TabPanePro, PatternFX, StagePro, etc.).
FX Flow 0.6.1 got released: declarative, fluent UI library for JavaFX. Adds validation support for atomic multi-value updates. More info by john16384 on Reddit/r/JavaFX .

Podcasts, Videos, Books

Frank Delporte published a blog and video : “Lottie4J started as a single question: can JavaFX render Lottie animations without a WebView? That question turned into a library. The library attracted pull requests. And now I had a 50-minute conversation with Naail Abdul Rahman, R&D engineer at LottieFiles, to talk about where the format is heading and what that means for a Java implementation.”
Pedro Duque Vieira shared a video on LinkedIn : “New capability added to the IKE Knowledge Layout Editor: display semantics can now be viewed in a table format. This provides a more structured way to inspect semantic information, which can be especially useful when working with large numbers of semantics.”
A live session of 2,5 hours with Johannes Rabauer and Anton Arhipov : Building a MIDI Visualizer with Junie, IntelliJ and JavaFX : “AI assisted development is becoming a core part of modern software engineering. But what does that actually look like in a real Java project? In this live coding session, we explore AI powered development inside IntelliJ IDEA while building a JavaFX application that visualizes MIDI music through animated waveform based visualizations. Rather than treating AI as a code generator, we will use Junie and other IntelliJ AI capabilities as development partners throughout the process. Together, we’ll explore how AI can help with architecture, implementation, refactoring, testing, and day to day development decisions.”
Frank Delporte interviewed David Gutierrez in a new video: JavaFX In Action #27 with David Gutierrez about JMathAnim to Create Mathematical Animations : “JMathAnim is a Java library and UI built on JavaFX that lets you create animated mathematical visualizations. The goal is simple: make it easy to build videos that explain mathematical concepts through animation. It’s inspired by the kind of content you see on YouTube channels like 3Blue1Brown.”

Lottie4J Meets LottieFiles: A Conversation with Naail Abdul Rahman

Tue, 09 Jun 2026 07:31:00 +0000

Lottie animations run on Android, iOS, and the web. Getting them working on the JVM is a different story. Lottie4J started as a question: can JavaFX render them without a WebView? That question turned into a library with a first release in March 2026! Since then, I received the first pull requests, recently added headless unit testing with JavaFX 26, and now this: a video conversation with Naail from the LottieFiles team.

A (removed) message by Street_Humor_7861 on Reddit : “Early contributors wanted for TailwindFX. An utility-first UI framework for JavaFX (MIT, 1.0-SNAPSHOT, actively developed). I’m building TailwindFX, an open-source framework that brings Tailwind CSS’s utility-first paradigm to JavaFX. Instead of writing verbose CSS/FXML or inline -fx-* styles, you compose UIs with familiar utility classes and type-safe Java APIs. " Check the repository here .
Striking_Creme864 on Reddit : “We recently introduced our CEFFX project (a library for integrating the Chromium Embedded Framework into JavaFX) and it was well received. Based on that feedback, we decided to simplify its usage by providing prebuilt native libraries. This allows you to use the library without having to compile anything yourself. All native binaries are packaged into the ceffx-natives module using classifier names similar to those in OpenJFX.”
Message by Dirk Lemmermann : “GemsFX 4.0.1 is out and has been ‘downgraded’ back to using Java 11 and JavaFX 17 due to popular demand. I also added a new sampler demo auto-update installer (jdeploy) that you can download here . The demo uses Java 24 and JavaFX 25.”
Screenshot shared by Dirk Lemmermann : “GemsFX 4.0.4 is out on Maven Central with fixes to the styling of the InfoCenterView. Try it out via the installer . Browse the available controls at gemsfx.dlsc.com .”
Message shared by Austin Lehman : “Aussom-Lang now has support for JavaFX, GTK4, a Java native interface with dynamic Jar loading, and native library interface via Panama. Quite a bit that can be done with it now. Aussom is a safe, sandboxed scripting language for the JVM. Embed it in your Java app, run it on the server with Aussom Server, or use it in the browser with Aussom-Script. " A JavaFX example is available in the documentation .
Frank Delporte announced “V1.2.3 of Lottie4J, the library for parsing Lottie animations as Java objects and playing them as JavaFX animations. In this release: improved unit tests, data model and player improvements, and more! All info in the release notes .”
Kareem shared a video on Reddit of DockTask : “JavaFX dynamic JAR based plugin system. The idea is pretty straightforward: users can upload their own JARs, and the app will load them at runtime thanks to Java’s serviceloader. It also connects to a remote repo to browse and display plugin information. It’s still a work in progress, but I’m really curious about what people think of this system. Any feedback would be appreciated! Check it on GitHub .”
Dirk Lemmermann shared a screenshot with a lot of AtlantaFX themes : “Release 1.3.0 of the new collection of AtlantaFX themes is out now and published on Maven Central. A total of 25 themes (14 dark, 11 light). Use the plain CSS files or the Java API.”

- Alt+Enter accessor intention
- fxp* completions
- Generate menu: JavaFX Property Accessors
- Generate menu: JavaFX Property
Striking_Creme864 on Reddit : “Recently, we introduced Weaverbird - a framework for working with dynamic plugins. In this post, we want to show a real example of how it can be used. The GUI is build on top of TabShell. The main idea is that a plugin configuration is represented as an XML file. When the application is distributed, it already contains predefined plugin configurations (at the same time, users can add their own plugins). A configuration contains module definitions, repositories used to download them, plugin metadata, and other related information.”
Last week, we included a link to the message by Dirk Lemmermann about AtlantaFX Themes. Now, there is also a website at with screenshots of all themes. “Each theme overrides the color scale, semantic tokens, and dark / light mode flag without touching the upstream stylesheet.”
Dirk Lemmermann announced version 4.1.0 of GemsFX : “now includes an AtlantaFX companion stylesheet for ControlsFX. You can use the method ControlsFXAtlantaFX.apply() to add this new stylesheet to your scene or any parent node. By doing so you will be able to get rid of all those pesky warning / error messages regarding CSS rules using unknown colors. For more on GemsFX see gemsfx.dlsc.com .”

In the JVM Weekly vol. 173, by Artur Skowroński : “MelodyMatrix by Frank Delporte isn’t important for what it does (it’s a music-related tool) - it’s important as a case study for how to ship a JavaFX desktop app in 2026. The release walkthrough on Foojay covers the full pipeline : jdeploy for cross-platform native installers, GitHub Actions for the build, auto-update integration, the works.”
Dirk Lemmermann is asking to get JetBrains to fix a JavaFX-related issue in IntelliJ IDEA."It is so disruptive to my ‘flow’.”

Debugging BentoFX in MelodyMatrix with Matt Coley, Scenic View, and an Honest Look at AI-Generated Code

Fri, 15 May 2026 10:02:40 +0000

There are bugs you can solve by yourself, and bugs where you just need to sit down with someone who knows the internals. This video is in the second category. MelodyMatrix uses BentoFX for its dockable panel layout. Branches, leaves, tabs on the side, content panels that open and close. It works well until something fights the layout. But I had some visual problems I could not explain, some code that felt more complicated than it should be, and no good explanation for why.

Testing Lottie4J JavaFX Animations in GitHub Actions Without a Display: JavaFX 26 Headless to the Rescue

Wed, 13 May 2026 07:35:26 +0000

When I released Lottie4J 1.1.0 , I mentioned something a bit embarrassing in the release notes and this blog post : there was a new unit test to compare the JavaFX player output against a JavaScript reference player, but it “can not run on CI, because it requires a display output.” A TODO. A known limitation. One of those notes you write hoping future-you will figure it out.

JavaFX 26 was released on March 17, 2026 and includes a new headless platform, allowing me to get the test running on GitHub Actions without a display.

Related to the three-monthly security update, a merge request has been created in the OpenJFX repo with the release notes for 26.0.1 with seven fixes and one known issue: “Media Playback Does Not Work on Ubuntu 26.04. This is because JavaFX Media does not support libavcodec version 62. Support will be added with JDK-8378510 .”.
Still on Java 8 with your JavaFX application and using Amazon Corretto? Apparently the April 2026 release is the last one Amazon is providing with JavaFX 8 support .

SceneBuilder

On Reddit, No-Security-7518 is asking for feedback: SceneBuilder is a GREAT piece of software. What features could make it even greater? : “I’m thinking maybe I could become a contributor. Anyway, I was thinking: What could make Scenebuilder even better?”

Applications

PDFsam announced : “The new PDFsam Basic 6.0.0 is out with a lot of work done on the PDF engine and accessibility, upgraded JDK and JavaFX and more. " Check this post for more details.
Frank Delporte did the first release of MelodyMatrix , live on camera, together with Steve Hannah , the creator of jDeploy . You can watch the full video on YouTube and find more information in this blog post . MelodyMatrix is a desktop app to experience music in a new way with real-time MIDI recording, multiple visualization views, and powerful playback features. Perfect for musicians, educators, and music enthusiasts.
Viktor Karpyuk shared on LinkedIn : “It started with a small frustration: Studio 3T Community Edition only allowed 3 database connections. That limitation kept getting in the way of real day-to-day work, so instead of working around it, I decided to build something simpler, lighter, and more practical for everyday MongoDB usage. That is how Mongo Explorer was born — a native MongoDB client focused on the things developers actually need: quick connections, easy browsing, solid querying, and a clean desktop experience without unnecessary overhead. " It’s available on GitHub .

Components, Libraries, Tools

Dirk Lemmermann shared amazing screenshots : “Last weekend I worked on FlexGanttFX (flexganttfx.com) improvements and support for AtlantaFX theming / styling. A new showcase app with new demos / samples is also in the works.”
Lee Wyatt announced JavaFX Tools v2.0 : “Free IntelliJ plugin for JavaFX devs. CSS completion, variable resolution and gutter previews, 63,000+ Ikonli icons browser, weekly JFXCentral LOTW digest. Thanks to Dirk Lemmermann for testing and guidance! " Check the video on YouTube . The plugin is available on the JetBrains Marketplace .
Hidekazu Kubota announced the first stable release of the JavaFX Builder API : “This API allows UI code to represent nested structures that mirror the container hierarchy of the user interface. This project aims to reintroduce builder classes to JavaFX. Although these classes were included in JavaFX 2, they were removed from the official library due to concerns about maintenance overhead. Nonetheless, for those who prefer a fluent style, having an API like this is a valuable addition.”
Shared by Striking_Creme864 on Reddit : “Running JavaFX apps with updates and dynamic plugins. Today I want to share our project Weaverbird and show how it can be used with JavaFX. Usually, a JavaFX application is started with all modules loaded int the boot layer. However, JPMS allows you to create an unlimited number of child layers and build a graph from them, which in turn lets us separate application management from the application itself. For exactly this purpose, Weaverbird was created - it runs in the boot layer and is responsible for creating and managing the layers (at the same time its capabilities go much further).”
Christopher Schnick shared info about KickstartFX v1.1 : “A few months ago I released a ready-to-use application template called KickstartFX . You can clone it and get started instantly or try out the pre-built releases on GitHub. The code and buildscripts are the same you find in a real-world production application as most of them are taken straight from one, in this case XPipe . Since then, quite a few additions and bug fixes have been integrated.”
Frank Delporte blogged about headless testing of Lottie4J , a library for parsing Lottie animations as Java objects and playing them as JavaFX animations: “Lottie4J had a unit test I marked ‘can not run on CI, because it requires a display.’ JavaFX 26 fixed that. There’s a built-in headless platform now, one JVM flag, and GitHub Actions just work without any display setup. There’s a small catch with Java version juggling (JavaFX 26 requires Java 24+, Lottie4J targets Java 21), but a Maven profile handles it cleanly.”
Dirk Lemmermann published a FlexGanttFX Showcase Application : “created a jdeploy installer for the FlexGanttFX showcase application. You can find it here . The installer will allow you to run the demo locally and the installation will auto-update whenever I push a new release. FlexGanttFX is a framework for building UIs for planning and scheduling applications. The showcase application contains a couple of demos and feature samples. If there is anything you would like to see being added to the demos then please let me know and I will try to come up with an example. I will soon add a JPro-based website that will allow you to run the same application in your browser.”

Catherine Edelveis published a new video : “New on CyberJAR: Comparing Top OpenJDK Distributions. If you’re looking for more than vanilla Java - JavaFX, Java 6 an 7, hardened container images, extended LTS support - check out this comparative summary.”
Live coding session with Johannes Rabauer and Ryan Jarvinen : “AI Coding with IBM Bob: Building a JavaFX Chess Game Live. In this live coding session we’ll we explore IBM Bob, IBM’s new AI-first development environment designed to act as a true software engineering partner rather than just an autocomplete tool. Bob integrates directly into the IDE and supports chat-driven development, real-time code review, and security-aware refactoring, while understanding your codebase and intent. It is purpose-built for tasks like Java modernization, large-scale refactoring, and enterprise-grade development workflows. The goal of this session is simple: Use a limited trial budget (40 Bobcoins) to build a functional JavaFX chess game and evaluate how far an AI IDE can realistically take us.”
And also a finished chess game in 3D by Olivier Pillods : “We were asked to replicate the classic chess game with JavaFX, and to add new pieces and rule variants. I was the only student that decided to make it 3D. Developed my own obj file importer. I created piece animations and colored interactions for movement availability. To finish, I made a graveyard system, and a rollback functionality that remembers all until start.”
Frank Delporte was “struggling with the BentoFX layout in MelodyMatrix, and called Matt Coley, the person who wrote it. We used ScenicView to inspect the running JavaFX scene graph, cleaned up some AI-generated code, and possibly found a bug. Honest and practical session. " Watch the video on YouTube and check the blog post with more info and links .
Video by Lee Wyatt : JavaFX Hot Reload in IntelliJ — One Click, Zero Code Changes (FxmlKit + JavaFX Tools) : “JavaFX hot reload without touching your production code. FxmlKit 1.5.1 introduces a system property to enable dev mode externally. JavaFX Tools 2.1.1 takes it one step further — just click the purple Runner button in IntelliJ IDEA, and your app starts with FXML/CSS hot reload enabled automatically. No need to call FxmlKit.enableDevelopmentMode() in your code. No risk of shipping dev mode to production. No extra configuration.”

MelodyMatrix V1.0.0 Released: Shipping a JavaFX App with jDeploy, GitHub Actions, and Auto-Update

Mon, 20 Apr 2026 14:51:00 +0000

Some side projects take a while to get to a proper release. MelodyMatrix is one of those. The app has been downloadable for quite some time thanks to jDeploy , but there was no official V1.0.0 yet. No tagged release. No moment of “okay, this is it.” Just a rolling build on every commit to the main branch.

That changed now: live, on camera, together with Steve Hannah, the creator of jDeploy.

Oracle's Java Verified Portfolio and JavaFX: What It Actually Means

Thu, 02 Apr 2026 07:01:48 +0000

Oracle’s JavaOne 2026 brought an announcement that caught some attention in the Java community: the Java Verified Portfolio (JVP), a new program that bundles JDK-related tools, frameworks, libraries, and services under a single commercially supported umbrella with clear roadmaps and support timelines. One of the headline items? Commercial support for JavaFX in JDK 17, 21, 25, 26, and future LTS releases.

Oracle’s own framing: “Driven by customer demand, interest from academia, and the growing need for advanced visualizations in AI-powered applications and analytics, Oracle is reintroducing commercial support for JavaFX.”

JavaFX Links of March 2026

Here are the JavaFX LinksOfTheMonth of March 2026. You can find the weekly lists on jfx-central.com . Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via [email protected] .

Core

Java and JavaFX 26 got released!
- JavaFX 26 requires JDK 24 or later.
- You can find all important changes, removed and new features, and fixed issues in the Release Notes for JavaFX 26 .
- You can download JavaFX 26 from the Gluon website .
- A remarkable move by Oracle : “Oracle is introducing the Java Verified Portfolio (JVP). This is a curated collection of enterprise-grade tools, frameworks, and libraries that Oracle commercially supports. … It is worth noting that JavaFX, the Java GUI framework, is once again supported via JVP. According to Oracle, this is due to growing demand. Support will be available for all new Java versions and all LTS versions during the five-year Premium Support tier. Support for JDK 8 will be extended until March 2028.”
- Blog post by Oracle : “Announcing the Oracle Java Verified Portfolio including Helidon and reintroduction of JavaFX Commercial Support.”
- Johan Vos announced : “Gluon continues to lead the OpenJFX project. Here is JavaFX 26. " With a link to a Gluon blog post about JavaFX 26 .
- Video with the recording of the talk by Kevin Rusforth at JavaOne: JavaFX 26 Today : “Building a compelling desktop app today requires features such as UI controls, charts, interactive media, web content, animation, CSS styling, 2D and 3D rendering, rich text, and property binding, with an easy-to-use programming paradigm that runs cross-platform. JavaFX is all this and more, delivering a rich graphical UI toolkit for building your applications and can also seamlessly interoperate with Swing. In this session you’ll learn about the new and exciting features we’ve developed over the past couple of years, culminating with the release of JavaFX 26. You’ll also get an update on RichTextArea. We’ll show plenty of demos and sample code, and finish with a sneak peek at what’s coming next.”
- APIdia announced : “Adjacent to Java releases are JavaFX releases. Of course, API documentation of JavaFX 26 is similarly available on APIdia .”
Quality Outreach Heads-up - JavaFX 27: Metal Is Now the Default Rendering Pipeline on macOS : “This heads-up is part of the quality outreach sent to the projects involved. … On macOS, the default JavaFX rendering pipeline has been switched to Metal since JavaFX 27 Early Access (EA) build 3. Metal provides improved performance and better compatibility on modern hardware.”
A blog by Gluon: The Art of the Backport: Why JavaFX Security Doesn’t “Just Happen” : “In a perfect world, keeping a tech stack current is as simple as bumping a version number in a pom.xml or build.gradle file. You run a clean build, and suddenly, the latest fixes are integrated. But for those of us building mission-critical desktop and embedded applications, “just upgrading” to the latest major release isn’t always feasible. When your application is built on a stable Long Term Support (LTS) foundation, you need that environment to remain predictable. You want the stability of your current version, but you absolutely need the security fixes that are discovered in the newer branches. This is where the “Art of the Backport” comes in, and it’s a significant part of the heavy lifting we do at Gluon.”
Related to the announcement of the Oracle Java Verified Portfolio (JVP) and the reintroduction of commercial support for JavaFX, Frank Delporte wrote a blog: The JavaFX Revival: Good News for the Community, Business as Usual for Azul .

Message by Jakob Jenkov : “I have started the process of building up the Polymorph Player in Java 25 and JavaFX 25. The code will now be located in the Polymorph mono-repo . The first bits are already there, but the player app does not do anything yet, except starting up 😊 But from now on, you can always clone or pull this repo to see just exactly how much is working, officially. This is a project where we can allow ourselves to question the entire current status quo of tech. Some should be kept - but other parts could probably be replaced with better formats / models / architectures. Let’s experiment to see what works, and what doesn’t.”
Frederick Salazar released OllamaFX v0.5.0 . “OllamaFX is a modern, native desktop client for Ollama, built with JavaFX. It provides a beautiful, user-friendly interface to manage your local LLMs and chat with them, featuring a sleek GNOME/Adwaita-inspired design.”

- And another release: “Version 1.2.0 of Lottie4J is out, and it’s again a big release! The headline feature is support for the dotLottie zip-container format, but that’s just the start. This release also brings marker-based playback, cropping, adaptive rendering, significant performance improvements, and a lot of core model fixes driven by testing more complex real-world animations. Detailed info and a video showing all new features are explained in this blog post .”
A good read by Liu Tiger : “JavaFX UI Automation: Challenges, Existing Tools, and Real-World Event Handling Problems. Automation testing has become a fundamental component of modern software engineering. In web development, automation ecosystems such as Selenium, Playwright, and Cypress are mature and widely adopted. However, the situation is very different for Java desktop applications, particularly those built using JavaFX.”
Pavel Castornîi is preparing a new release of TabShell , “a platform for building tab-based applications in JavaFX, where an application is structured as a tree of MVP components, each of which has its own lifecycle, history, etc. The platform provides abstract classes for creating the main types of components: tab, area, page, dialog, and popup, as well as containers for them.” Try it out and let him know if there are any remarks…
Gerrit Grunwald created svgconverter : “An SVG to JavaFX converter that can handle nearly everything except animations and masking. You can load a svg file and render it either to the JavaFX SceneGraph using nodes or to the JavaFX Canvas. It took some time to get the Canvas thing working because it is missing some things but now it works kind of ok.”
Dirk Lemmermann announced: “I created a new website for GemsFX that will give you an idea which controls are available in this library.”
Lee Wyatt shared the new library CarouselFX : “A JavaFX carousel / slideshow component with 70+ built-in transition effects. " Demo on YouTube and sources on GitHub .

Dirk Lemmermann “did some more evaluation of GitHub Copilot CLI today and built a nice launcher app for my GemsFX open source project. The productivity I get out of this surpassed all my expectations.”
Post by Gluon : “We’ve all been there. You’re working on a JavaFX application, and you hit that wall. Maybe it’s a strange rendering glitch on a specific OS, a memory leak you can’t pin down, or a performance bottleneck that only appears in production. You search the forums. You check Stack Overflow. You spend days tweaking code, hoping for a breakthrough. There is a faster way! To make it easier for teams to experience the value of expert support, we are introducing a one-time JavaFX Quick-Fix Package.”

Lottie4J 1.2.0: dotLottie Support, Marker Playback, Cropping, and a Big Speed Boost

Tue, 24 Mar 2026 07:51:00 +0000

Version 1.2.0 of Lottie4J is out, and it’s again a big release! The headline feature is support for the .lottie container format, but that’s just the start. This release also brings marker-based playback, cropping, adaptive rendering, significant performance improvements, and a lot of core model fixes driven by testing more complex real-world animations.

dotLottie File Support

Until now, Lottie4J only supported the plain JSON format (.json). That’s the original Lottie format, but LottieFiles also introduced a newer container format: .lottie. It’s essentially a ZIP archive that can hold one or more animations, embedded images, sounds, and a manifest file that describes the contents.

Lottie4J 1.1.0: Better Rendering, Smarter Debugging, and an animated Lottie4J Logo!

Fri, 13 Mar 2026 07:30:00 +0000

Just one week after the first public release of Lottie4J , the open-source Java library for rendering Lottie animations in JavaFX, version 1.1.0 is already out. And it’s a big one!

A lot happened in that one week. A logo was designed for the project, a Lottie animation was created for that logo (naturally!), and, most importantly, a significant number of rendering improvements landed after testing a much wider range of animation files. That’s the reason for the version bump from 1.0.0 to 1.1.0: there are some API changes that come with it.

Introducing Lottie4J, a Java(FX) Library to Parse and Play Lottie Animation Files

Tue, 10 Mar 2026 08:24:00 +0000

I’m proud to present a new JavaFX library: Lottie4J, that brings Lottie animations to JavaFX applications. I first learned about Lottie many years ago when we were developing a mobile app. We used Lottie animations to explain to users how to operate a physical device. The animations made the instructions so much clearer than static images or text alone.

At the time, I wanted to create a similar experience in JavaFX, but I couldn’t find a JavaFX player for the Lottie format. So I decided to build one myself. What I didn’t realize then was just how complex this journey would be…

New JavaFX In Action interview published by Frank Delporte : “While reviewing scientific papers, Lidiany Cerqueira had a recurring problem: each reference needed to be checked, as more and more of them were #hallucinations introduced by LLMs and Chatbots. As a solution, she created CERCA during her Christmas holiday. Thanks to #Java, #JavaFX, open-source libraries, and free APIs, the number of references to be checked gets reduced a lot, making her work and that of many other reviewers a lot easier! " You can find the video interview on YouTube and more info in this blog post .

" The source (in one single file!) is available on GitHub .

Tutorials

Nicolas Frankel published do Foojay.io: From a JAR to a full-fledged MacOS app . “The solution is straightforward: create a regular MacOS app from the UberJAR. At its simplest, a MacOS app is only a folder with a specific structure. You could replicate it by hand, but I’m lazy, and there are tools for this. jpackage is such a tool. jpackage is one of the tools I learned about, am ecstatic about, used once, and forgot until the next time. Add one to the counter.”

Java UI in 2026: The Complete Guide by Robin Tegg : “When developers think about building user interfaces today, the conversation often revolves around the same familiar choices. But Java offers a fully modern, end-to-end alternative — desktop, web, terminal, and even mobile apps — all powered by a single language. With one cohesive Java stack, teams and AI tools can reason, build, and iterate more efficiently than ever. "
- This guide (and JavaFX) are also mentioned in the JVM Weekly newsletter by Artur Skowroński .
Jakob Jenkov shared a quick update about the Polymorph project : “The Polymorph Player is beginning to take shape. It can only display some very simple graphics at this point, so I will not include a screenshot in this post. At this point the main structural design is reasonably in place. From here on it is hundreds, if not thousands, of small improvements that need to be added before the Player has a somewhat useful and coherent base set of functionality. These improvements are both in the Player itself, and in the Polymorph Tools toolkit - especially in the virtual machine that executes the scripts which can be run from within the Player app. Lots of work to do ! … but it’s in progress ! 😊 The Player app is made with JavaFX, by the way! ☺️”

Here are the JavaFX LinksOfTheMonth of January 2026. You can find the weekly lists on jfx-central.com . Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via [email protected] .

Core

Gluon published quarterly releases of:
- JavaFX 25.0.2
- JavaFX 21.0.10
- JavaFX 17.0.18
- Read more in this blog post: “Securing the Future of OpenJFX: January 2026 Critical Patch Update Released ”.
Message by Johan Vos : “Maintaining LTS versions for a project like JavaFX is complex and resource-intensive. It requires a fair amount of the Gluon resources, but it is extremely important to keep JavaFX secure, modern and relevant. You can support us at gluonhq.com/lts .”
The Azul release notes show the list of Fixed Common Vulnerabilities and Exposures in this release. There are 11 in total, of which 7 are related to JavaFX.
Lee Wyatt has a proposal for a missing component in JavaFX : “It is missing a native Switch control — every major UI framework has one except JavaFX. I’ve implemented a SwitchButton with full theme support. Hope to contribute to OpenJFX. Check the README for details on why JavaFX needs this.”

Applications

Message by JabRef : “_Thanks to the cool feature of #javafx called the shortcut modifier, we can now display and handle the keyboard shortcuts in a more OS independent way. On Linux and Windows cmd key will be replaced with ctrl automatically and option key with MARKDOWN_HASH34823136d0dd91d0f5d22db740f7679cMARKDOWNHASH. Grab the latest version here .”
- And a blog post announcing an alpha release : “Happy Holidays from the JabRef Team! We have a present for you: We are happy to announce the release of JabRef 6.0 Alpha 4, the next step towards the stable version of JabRef 6.0. This alpha release brings a number of bug fixes, improvements, and new features, as well as some changes under the hood in the machine room of JabRef, to make future improvements easier and JabRef more versatile.”
Release v25.2.0 of LogoRRR with several improvements and bump to Java(FX) 25.
Message on Bluesky by mapton.org : “Hello, World! So, after more than three years this account is now back online posting about its development progress among other things. Mapton is powered by Java, JavaFX, and the Netbeans platform among other great open source projects. "
- Mapton v26.01 is now available : “Let’s start this brand new year with a brand new version of Mapton.”
Patrik Karlström is having fun : “As a weekend project I made an earthquake module for Mapton with data feed from usgs. The image shows recent quakes, but you can pretty much filter on any attribute. Colors indicates age in days, circle and lines the magnitude.”
A video on Reddit of Mable , a cross-platform deadline management application, created by @n-xiao . Sources are available on GitHub . “Mable is an application which allows you to create Countdowns — it counts down the days till a date you set. When a Countdown approaches or passes its due date, the built-in Heads Up Display will update, showing you how many Countdowns are either overdue, due today or due tomorrow. Mable is not intended to replace your Calendar or To-Do list. Instead, it provides you with a quick overview about how much time you have left for multiple deadlines.”
Lidiany Cerqueira built a tool to detect AI-generated fake references in academic papers. A long and detailed post is available on dev.to . “Seeing the flawed metadata published in a journal was a wake-up call that led me to build CERCA, an open-source tool designed to assist researchers, reviewers, and editors in quickly verifying the accuracy of references. It was developed to improve trust, transparency, and reliability academic writing. "
- She also announced CERCA v1.2.0-alpha : “New feature: Manual Reference Entry. If it can’t read your PDF, paste your reference list. It’s now on SourceForge !”
- And in another message from Lidiany on Bluesky : “Started the day chatting with Frank Delporte . We had a great time talking about Java, JavaFX, and CERCA. I highly recommend his YouTube channel , if you’re interested in Java.” The recording of that interview will soon be available on YouTube in the #JFXInAction series.

Games

Defold Engine published their Showreel 2025 : “We’ve gathered some of the best #MadeWithDefold games released over the past year in our traditional annual video. "

- Here is an interview with Vlad Protsenko , one of the developers of Defold and the creator of Cljfx, a declarative, functional and extensible wrapper of JavaFX for Clojure .
Mark J. Koch shares a screenshot on Bluesky : “I’ve made a lot of progress on my neuromancerpc restoration and it’s largely playable (let’s call it alpha), but I’m not done reverse engineering the original game’s data files…”

Components, Libraries, Tools

A lot of library updates by Dirk Lemmermann this month!
- About FlexGanttFX: “I finally managed to create a jdeploy installer for FlexGanttFX. You can find it on the updated FlexGanttFX.com website under ‘Downloads/Demo’. The demo shows how this custom JavaFX component manages to draw thousands and thousands of activities below a timeline.”
- “A new FlexGanttFX demo app installer is available online now … These are basically interactive unit tests for various features available by this control. If you are doing planning and scheduling apps, this control is for you.”
- This screenshot of a FlexGanttFX demo shows how it can be used to visualise a project plan imported from MSProject.
- About FxmlKit: it’s a modern JavaFX FXML framework with hot reload, zero-configuration loading, and optional dependency injection. Lee Wyatt shared a video on Bluesky and on YouTube : “Implementing FXML and CSS hot reloading in FxmlKit. Edit, save, and see the results immediately. No more rebuild-restart loops! " And Dirk Lemmermann announced v1.5 .
- Release 3.4.2 of PDFViewFX is out now . “The visual properties of the view can now be styled via CSS and not just via API. " More info on GitHub .

Podcasts, Videos, Books

Published on Foojay: Video series “JavaFX In Action”, Part 6 with Vlad Protsenko (Clojure), Matt Coley (Recaf), Craig Raw (Sparrow), and Florian Enner (3D Robot Visualization).
Helal Anwar shared a new video: Devlog 4| Student management app (Part 4) .
Frank Delporte continues his #JavaOnSingleBoardComputers and published a video and blog with more info showing Java and JavaFX on an OrangePi 5 Ultra with ARM processor. As expected, JavaFX doesn’t work on an OrangePi RV2 with RISC-V processor. Challenge for 2026: Who can build JavaFX on RISC-V?
A video by Binary Academy : JavaFX 3D Solar System Full Animation Tutorial | Planets Orbiting Around the Sun .

Tutorials

Carl Dea updated his blog series from 2022 on Foojay.io “Project Panama for Newbies” . In Part 4 you can read more about “Imagine C code capable of performing a computation and after its completion the C code will notify Java code to perform updates to JavaFX UI components…”
Post by iifx.dev : From Modules to Databases: Solving Hibernate Visibility Issues in JavaFX and Maven : “Integrating Jakarta Persistence (JPA)—specifically Hibernate—into a modular (JPMS) JavaFX application can be a bit like solving a puzzle. Because the Java Module System is very strict about visibility, getting Hibernate to talk to your private entities requires a few specific ‘handshakes.’ Here is a guide to getting this working smoothly.”
Video tutorial by Hacktrickz : “31.1: JavaFX Introduction, Setup & Application Structure| [Abdul Bari] Java course ”
Video tutorial by Kawsar Technologies : “Part 13 | User Management System in JavaFX & MySQL | Fetch Assigned Roles & Display Them in Table ”

Miscellaneous

Dirk Lemmermann on Bluesky : “The online JavaFX ‘Ensemble’ demos are pretty cool. Wished more library developers would leverage it. Check jfx-ensemble.com .”
Matt Coley is asking for feedback : “Any JavaFX people experience removed nodes being stuck around in memory after they’ve been removed from the scene graph? If I have a node that has a ~500 MB byte array, and then I remove it, I should be able to expect that to be freeable right?”
Found on Hacker News by ezst : “Call me an idiot, but I still gladly take Swing and javafx over JS and monstrosities like react. The state of Qt is also very good. Web won because the distribution model is easier on the user, and because managers thought UX designers would be making whole apps now, saving on rates. Not because it’s technically superior.”
In March 2024, ArcGIS announced that they were deprecating ArcGIS Maps SDK for Java. In a new blog post by Lucas Danzinger they explore a technique of using ArcGIS Maps SDK for Qt as a map control in a JavaFX based application: “Through the above techniques, we’ve shown that it is possible to display a Qt MapView in Java, as well as to have two-way communication between Java and Qt via JNI. While this example is by no means a silver bullet, we hope that it might be an inspiration on how you can continue to move forward with your JavaFX apps using the latest ArcGIS technology.”
Interesting discussion on GitHub : Can CheerpJ be integrated in WebFX ?
- “CheerpJ is a JVM and a distribution of OpenJDK for the browser in WebAssembly and JavaScript. Now supporting Java 8, Java 11 and Java 17 (preview), with Java 21+ coming in 2026.”
- “WebFX is a JavaFX application transpiler powered by GWT. It can transpile a JavaFX application into a traditional self-contained pure JavaScript web app (with no plugin or server required for its execution in the browser).”

Core

A one second, but still impressive, video on YouTube by Carl Dea : “I was able to get 100,000-2M particles ~ 120fps using Apple’s Metal API on M4/GPU, using Java 25 FFM (project Panama), JavaFX WritableImage API. Of course there are more optimizations but really excited to be able to mix Java/JavaFX code with native bindings in a memory safe way. Still more to learn and do. There are different strategies to avoid data copies between CPU and GPU.”

Applications

Juan Antonio Breña Moral created an “animated spinning ripple surface rendered with JavaFX” using MemorySegment from the FFM API (Java 22+), JEP 454 , to increase performance. Sources and screenshot on GitHub .
Patrik Karlström released CRIC 25.12 : “CRIC is a Java custom runtime image creator, a GUI for jlink. It’s built with JDK 25, JavaFX and the Netbeans platform. Downloads available for Windows and Linux , including appimage and Snap.”

Components, Libraries, Tools

Message by Dirk Lemmermann on Bluesky : “Check out FXMLKit. Another convention-over-configuration framework that removes boilerplate code for loading screens done in FXML. It is inspired by afterburner.fx but also supports JPro multi-user sessions and dependency injection for nested components. " Sources and more description on GitHub and available from Maven Central.
- Version 1.2.0: “It now also supports hot reloading of FXML and CSS. Yes, that’s right … see the changes you made to FXML without restarting your application.”
- Dirk Lemmermann announced v1.3.0 of FxmlKit : “Fixing an issue related to hot reloading of user agent stylesheets of custom controls. It had too many side-effects. It can still be enabled, but by default it is off.”

Podcasts, Videos, Books

A new JFXInAction interview by Frank Delporte : “Florian Enner impressed me at the Devoxx conference with his 3D visualizations and scientific charts with millions of points, showing real-time data received from robots and sensors. And using the same code, he does this in both desktop and mobile apps! Awe-inspiring work, making maximum use of the powers of hashtag#Java to combine network communication with a JavaFX user interface. And he also shows some amazing things with a JavaFX UI in a C++ application!”
Lazy Brownie recorded the coding process of a Two Player Pong . No shared code, no comments, just some relaxed music and a screen recording 🙂

Tutorials

New tutorial videos this week by Troels Mortensen :
- The Controller Factory
- Changing views through events

Miscellaneous

A Bluesky thread by Sean Tilley : “For my capstone project in Computer Science, I’m writing a desktop music player in Java. I’ve never tried to build one before, but it seems like a decent challenge, and it covers the different data structures we’ve learned about. … Playback will also be interesting to figure out. Java’s audio API doesn’t support MP3 out of the box, but JavaFX does.”
Similarly, Kz needs to create a game : “I am required to make a game in JavaFX for a University project and I have zero experience in video game dev.”
Repost of the article by Frank Delporte on Foojay : First Experiments with Java on the LattePanda IOTA: An Alternative to Raspberry Pi? “Since I installed the Java version from Azul with JavaFX included, I could also run a JavaFX demo application. … The application ran smoothly! It showed we’re running on a Linux 64-bit system with Java 25.”
The JavaFX plugin in IntelliJ IDEA is marked as ‘Ultimate Only’ in the unified distribution IDEA 2025.3. But no panic, it’s a bug : “Until the fix is out, you can install the previous version 2025.2.6 of IntelliJ IDEA to bypass the issue.”
On Reddit, Rvaranda shared a video and is asking for support : “I’m having a weird problem with FXGL. Don’t know if it’s FPS related, but what happens is, when I start the game, the app’s timer spikes up very briefly at the start, then it stabilizes. As a result, all moving entities moves very quickly initialy, then they slow down to their actual speed.”
Clément de Tastes shared a screenshot : “Exploring Mandelbrot’s fascinating fractals has been a wonderful way for me to play with Java features. It started as a JavaFX project only, then became the perfect playground to experiment with upcoming features such as Valhalla Value Types and the Vector API. Special mention to FFM as well.”

Fri, 26 Dec 2025 08:07:18 +0000

This is the next part in the series of “JavaFX in Action” interviews. Are you working on a fantastic JavaFX application? Let me know, and let’s discuss it in the new year!

Vlad Protsenko: Combining Clojure with JavaFX for Game Development with Defold

Vlad Protsenko is a Senior Developer with proficiency in many JVM-based languages. He worked both in very small and large teams, gaining experience in developing projects of various sizes, from scratch and from legacy codebases. He enjoys full-stack development, writing backend, frontend, and Android applications. He started as a game developer and switched to developing enterprise software, currently mixing both at Defold.

First Experiments with Java on the LattePanda IOTA: An Alternative to Raspberry Pi?

Thu, 11 Dec 2025 09:13:14 +0000

After years of experimenting with Raspberry Pi boards, Java, JavaFX, and Pi4J to control electronics, I wanted to explore whether my knowledge and experience could be applied to similar boards from other providers. There are many alternatives available these days, based on ARM, Intel processors, and RISC-V architectures.

I reached out to several suppliers to see if I could get evaluation copies, and I’m happy to share that I received my first box from DFRobot containing the LattePanda IOTA .

JavaFX Links of November 2025

Sun, 30 Nov 2025 06:42:41 +0000

Here is the overview of the JavaFX LinksOfTheMonth of November 2025. You can find the weekly lists on jfx-central.com . Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via [email protected] .

Core

Article by Paul Krill on InfoWorld : “Will JavaFX return to Java?” “Just as a proposal to return JavaFX to the Java Development Kit has drawn interest in the OpenJDK community, Oracle too says it wants to make the Java-based rich client application more approachable within the JDK. … An October 29 post by Bruce Haddon on an OpenJDK discussion list argues that the reasons for the separation … are much less applicable today. "
- Frank Delporte sees a perfect match with the Java on Mobile project and published a post about it: Will OpenJFX Be Merged Into OpenJDK? It Would Be a Perfect Match with Java on Mobile! “Again, some exciting developments seem to be happening in the Java world! There’s a growing discussion about bringing JavaFX back into the OpenJDK, and it couldn’t come at a better time, especially with Johan Vos and the team at Gluon working hard on making Java a first-class citizen on mobile platforms. … I’m excited to see where this goes. Java has always been about ‘write once, run anywhere,’ and these initiatives could finally deliver on that promise more completely than ever before.”
- This post got also republished on Foojay.io .
Request by Johan Vos : “JavaFX developers using Windows: please help the development by doing some performance test for Direct3D 12. " More info in this mailinglist message by Lukasz Kostyra .
Article by Ben Evans on InfoQ : “Running Java on iOS: Gluon Introduces OpenJDK Mobile Resources and Automated Build Pipelines”. “The long-awaited Hotspot-on-iOS project is reporting major progress - OpenJDK is now able to build and run on iOS. This is the next milestone on a journey that started a long time ago - InfoQ first reported on it back in 2015. More recently, the mobile repository of OpenJDK (which is downstream of the main repo) has been able to build a static version of libjvm, allowing iOS binaries to execute Java code.”
Message by Johan Vos highlighting the fact JavaFX is a full open-source project: “Keep in mind that the Gluon LTS releases of JavaFX 17u and JavaFX 21u are free to download and use. With Gluon, we do offer an LTS service but the releases themselves are really free. We don’t want to charge people for creating JavaFX applications. No reason to pay unless you need support. "
- And he is looking for feedback about a core JavaFX feature : “The JavaFX Properties/listeners approach is really powerful to bind UI components to changing values. But it is often over-used and the main source of performance issues. It’s very easy to kill performance by adding a listener to a property that is modified during layout.” What do you think? Did you experience such performance issues?

Applications

Rafael Gutierrez shared on Bluesky : “A Pomodoro Timer built with JavaFX and Spring Shell using Hexagonal Architecture (any feedback is welcome.)_” You can find it on GitHub .
Gerrit Grunwald updated JDKMon to Java(FX) 25. Downloads are available on GitHub . JDKMon is a little tool written in JavaFX that tries to detect all JDKs installed on your machine.
codedead announced Opal v1.5.1. Here are the release notes . “Opal is a simple app that includes different sound groupings to suit anyone, from office to fantasy. All have volume controls so you can keep faint in the background or bring them forward. You can also set up a delay timer from the settings tab to remind you to take a break. You also have the option to combine multiple sounds at varying volumes to produce the perfect background noise.”
Cormac Redmond shared an impressive screenshot showing a lot of different UI windows of KafkIO: “Version 2.0.14 is released, packed with new features. Download the fast, easy Apache Kafka™ GUI .”

Games

Gerrit Grunwald updated SpaceFX to Java(FX) 25. Downloads are available on GitHub . SpaceFX is a space shooter written in JavaFX. It can run on Mac, Windows, Linux, on mobile devices, and even in the browser. A true “write once run anywhere” application that illustrates the true power and the promise made by Java and JavaFX.
Defold, the free game engine with a JavaFX UI engine, shared : “The Defold Editor Overview manual has been updated! Get familiar with the new Editor features and let us know if there is anything we could improve further.”

Components, Libraries, Tools

Message on Reddit JavaFX by Bruno Salmon : “WebFX now supports TeaVM: bringing WebAssembly and Kotlin to JavaFX on the Web!” with a link to a full blog post : “We’re excited to announce that WebFX now officially supports TeaVM, a Java to WebAssembly compiler that unlocks faster startup times and broader JVM language compatibility with now Kotlin and Scala! We already have multiple live demos running with TeaVM.”

Podcasts, Videos, Books

Frank Delporte interviewed Johan Vos and Stephen Chin at Devoxx Belgium 2025. The video is now available on YouTube .

Miscellaneous

Gerrit Grunwald has fans! 😉 : “Yesterday at the event of the Amsterdam JUG, someone from the audience came to me after my session and thanked me for creating the JavaFX libraries I did create… It always makes me really happy to see people use the things that I just created for the fun of it. Love the Java Community.”
Interesting read: Solving the Java 24/JavaFX 24 Compatibility Issue: Unsafe Access Flag . “The warnings you’re seeing, especially those related to sun.misc.Unsafe and WARNING: package sun.misc not in java.base, are a direct result of JEP 471 and JEP 498 in the newer Java versions (starting around JDK 23/24). … Future JavaFX Versions (JavaFX 25 and beyond) are expected to have this internal usage removed or replaced with modern alternatives (like the Foreign Function & Memory API introduced in Java). Until then, using the –sun-misc-unsafe-memory-access=allow flag is the correct way to handle this transition period. You should keep an eye on the JavaFX release notes for updates on when this internal dependency is completely phased out!”
Mark J. Koch needs a JavaFX-break : “My end of the year goal is to make this pile of circuits into a working analog synth. Then, and only then, am I allowed to go back to gamedev on my JavaFX Neuromancer PC remake while sipping egg nog. Too many hobbies.”
Screenshot by jaavaaguru on Reddit : “I’m working on a theme designer app, and came up with this color picker idea this morning and implemented it from scratch. Any thoughts for improvements?”
Frank Delporte introduced the new hashtag #JavaOnSingleBoardComputers . “Thanks to DFRobot, I took my first step toward testing other single-board computers with Java, JavaFX, and Pi4J. The LattePanda IOTA looks like a great board and calls for more experiments after a quick first test… " Video and blog are available here and show a JavaFX JBang application running smoothly on the IOTA.

Will OpenJFX Be Merged Into OpenJDK? It Would Be a Perfect Match with Java on Mobile!

Wed, 26 Nov 2025 09:18:36 +0000

While looking for articles for the JFX Central Links Of The Week , I found this very interesting article by Paul Krill on InfoWorld . It’s based on an October 29 post by Bruce Haddon on an OpenJDK discussion list in which he argues that the reasons for the separation of OpenJFX from OpenJDK in Java 11, more than seven years ago, are much less applicable today.

Again, some exciting developments seem to be happening in the Java world! There’s a growing discussion about bringing JavaFX back into the OpenJDK, and it couldn’t come at a better time, especially with Johan Vos and the team at Gluon working hard on making Java a first-class citizen on mobile platforms.

Foojay Podcast 83: OpenJDK Evolutions plus Tips and Tricks

Mon, 24 Nov 2025 06:07:00 +0000

Welcome to another episode of the Foojay Podcast! Just like in the previous episode, I bring you conversations from two of Europe’s premier Java conferences - Devoxx in Belgium and JFall in the Netherlands.

At these conferences, I had the opportunity to speak with members of the Java community about topics ranging from the evolution of Java itself to mobile development, performance optimization, and even automotive security.

My first guest is Johan Vos, a Java Champion who takes us on a journey through Java’s history - from porting Java to Linux in 1995 to his current work on bringing Java and JavaFX to mobile and embedded devices through the Java On Mobile project.

JavaFX Links of October 2025

Fri, 31 Oct 2025 07:31:45 +0000

Here is the overview of the JavaFX LinksOfTheMonth of October 2025. You can find the weekly lists on jfx-central.com . Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via [email protected] .

Core

Article by Paul Krill : JavaFX 25 previews JavaFX controls in title bars. “Preview feature in latest update of the Java client application platform defines a Stage style that allows applications to place scene graph nodes in the header bar area.”
Johan Vos is working on Java on Mobile : “I can now run HelloFX on an iPhone. This required only really minor changes to OpenJFX and OpenJDK, and I’ll update github.com/openjdk-mobile/openjfx-build as soon as I find some time. Most of the work (> 99%) went into understanding the tons of options in XCode. Next step is the integration of Leyden code into OpenJDK/mobile. Hope to get support from the Leyden experts.”
Message from Gluon : “The CPU releases for JavaFX are available. Download the latest JavaFX SDKs with security fixes or get them from Maven Central. You’ll find the latest released, JavaFX 25.0.1 and the Gluon JavaFX LTS releases 17.0.17 and 21.0.9.”
Is the “OpenSource Model” broken for OpenJFX (and all other projects)? And are those who are making money from it not interested in fixing it? Interesting discussion on Bluesky …

SceneBuilder

Plant Fall is working on a SceneBuilder-alternative without XML, see the video on YouTube . Looks like it’s in early stage, curious to see how it will evolve…
- Plant Fall published a new video about a SceneBuilder-alternative without XML: “In this video , I show the progress of Morphos Desktop FX – Version 2, a powerful GUI builder that lets you create your JavaFX interfaces visually — and now it can generate complete source code and save your layouts as JSON files.”

Applications

Patrik Karlström released version 25.09 of nbRsync , a rsync GUI: “It’s mostly about dependency updates such as Netbeans 27, JDK and JavaFX 25. " You can find it on GitHub .
Video shared by LogoRRR on Bluesky : “Working on a nice addition to LogoRRR - Group and reuse your search queries! Reapply them to your multiple log files - this will surely save you time. This will be part of the next release. "
- LogoRRR shared a screenshot of an upcoming release : “The goal is absolute simplicity for you, which requires a lot of development and careful planning behind the scenes.”
Patrik Karlström announced Mapton 25.10 : “…the open source Java(FX) based generic map platform built on WorldWind Netbeans 27 platform & JDK 25. 👋 Downloads with runtime from Azul are available for Windows & Linux (including appimage & snapcraft).”
Message by Mirko Sertic : “I found some time to update JavaFX DesktopSearch to the latest Java 25, Lucene and#Tika releases. Maybe I will also add some LLM or MCP features. We’ll find out. Checkout on GitHub for more to come 🙂”
v3.25.0 of binjr, a standalone time series browser, is now available : “Aside from being based on the latest Java25 runtime — making this a somewhat themed release — the main features this time around are: much improved support for the ZGC garbage collector logs files for the OpenJDK JVM, improvements to handling of CSV files with things like support for comments and better number parsing for uncommon notations, bug fixes, and quality of life enhancements. Full changelog and download links are available on binjr.eu .”

Games

No JavaFX, but still very impressive Java-based game development: Nostr Game Engine on GitHub and here is the website . “Based on jMonkeyEngine. A game engine and framework for building games and applications integrated with the Nostr ecosystem and p2p networking.”

Components, Libraries, Tools

KickstartFX is an impressive project by Christopher Schnick : “An advanced, ready-to-use template for JavaFX applications. It can serve as a solid foundation for your own JavaFX application as everything is fully customizable and extendable. KickstartFX is much more than just a basic template that opens a simple window. It contains a lot of code to handle the challenges of applications in the real world to achieve the best possible desktop application experience across all operating systems. The code is based on XPipe , a well-established JavaFX application, and is the result of years of experience developing a desktop application that is used by many thousands of users right now. " Very detailed documentation is available here and the sources are available on GitHub .
JPM promises to provide a better experience compared to Maven and Gradle : “_Imagine if it was simple to create a desktop app in kotlin…. Wait it is: jpmhub.org : MARKDOWN_HASH141e92adc7387a4d2beb57a986c7513bMARKDOWNHASH.”
- JPM shared a video : “To show the true power of JPM I created Neutron, a native app builder that leverages the power of JavaFX’s webview for easy development. " Sources on GitHub .
Message from Clément de Tastes : “A major milestone has been reached on the quarkus-fx extension as it now supports native build in its 0.10.0 release. Please report any found issue .”
Message by Dirk Lemmermann : “Chasing memory leaks in my JavaFX based application is a breeze when using JMemoryBuddy from Florian Kirmaier I add it to my prod code, not just test classes. At any time I can see whether UI views got garbage collected or not. When I see that a view did to get garbage collected I launch VisualVM , search for the JMemoryBuddyLive instance (in the heapdump) with the uncollected view, click on the ‘referent’ and open the ‘GC Root’ view. That tells me what is still holding a reference to the view. "
- And Dirk shared screenshots : “I have added an updated and improved version of the SegmentedBar control to GemsFX. Will be released today in version 3.6.0. This is a real-world example of the SegmentedBar control being used. Our app is using it as part of the ‘debt collection’ user interface. It shows how many bills haven’t been paid, how many have started the collection process, etc…”
- Followed by screenshots of version 3.6.1 : “I have added a new ‘StretchingTilePane’ container so that I can finally create a nice responsive tile-based layout for the module selection view of our CRM solution. The default JavaFX TilePane does not fill the available width. It also came in handy for the launch pad section of our “market data portal”. Each card is a “tile” and depending on available width we want to either have two or three of them in a row.”

Many thanks to Kevin, Ambarish, Ajit, Jayathirth and others for their great work.”
Message by Johan Vos (inspired by the Graal-related announcement of Oracle ): “To be very clear on the broader OpenJDK-mobile initiative we announced last month with Gluon : this is all based on open-source tech (github.com/openjdk/mobile) . We deliberately avoided dependencies on company-owned products. We very much depend on, and leverage the great technical work, including the open discussions in OpenJDK mailing lists, GitHub PR’s and JBS issues. Important to make the distinction between the top-quality work from engineers and the strategic decisions made by companies.”

Announcement with screenshots by Dirk Lemmermann : “CalendarFX 12.0.1 has built-in support for AtlantaFX. Several themes and dark mode support for free.”
Hidekazu Kubota announced on Bluesky : “I’m releasing the results of my one month of effort. The JavaFX Builder API Project provides a builder pattern API for JavaFX UI components, enabling the creation of JavaFX applications through a fluent, strongly typed, and declarative approach. This adds flavors that fluent API enthusiasts will appreciate on top of the original JavaFX API. Currently, it is a SNAPSHOT version that can be tested by adding it as a Maven dependency. I plan to release an early access version next, but before that, I would like feedback from JavaFX developers.”
Hidekazu Kubota on Bluesky : “I have been developing a VSCode extension to generate JavaFX builders, but I decided to rewrite it as a library for a better approach. Recognizing the library’s clear potential, I chose to halt the development of the extension. "
- And a follow-up message : “The JavaFX Builder API has been updated to support JavaFX 25. Since the JavaFX API is quite stable, I believe that supporting it through a code generator approach is straightforward.”

Johan Vos on Bluesky : “There are so many cool performance tricks for JavaFX that I sometimes think I should write a book about it. But that takes a huge amount of time. I’ll think a bit more about how to deal with this.”
Dirk Lemmermann uses JavaFX styling in the best possible way : “‘Empathy driven development’”’ means to consider that there are users out there with disabilities. One of them is ‘color vision deficiency’ (CVD), and today I added a preferences pane that allows our users to pick their status colours based on their CVD.”
And another message with screenshot by Dirk : “Once again amazed how well JavaFX runs inside browsers via JPRO .”
Frank Delporte bumped his Raspberry Pi’s to version 25 : “Welcome to Java 25 on the Raspberry Pi! The install script in the Pi4J OS repository to configure a new Raspberry Pi has been updated to install Azul Zulu 25 with JavaFX. Or you can follow the updated instructions on the Pi4J website .”

Catherine Edelveis struggled with a delay when starting sounds on macOS versus Linux and shared the solution : “I found the culprit of sound latency with JavaFX on mac - the mp3 format! Converted to wav, and everything works as a charm now. Heads up to everyone: mp3 is evil even in such non-trivial cases.”
An interesting pull request by Ambarish Rapte in the OpenJFX project: “_This is the implementation of new graphics rendering pipeline for JavaFX using Metal APIs on MacOS. We released two Early Access (EA) builds and have reached a stage where it is ready to be integrated. Default rendering pipeline on macOS has not been changed by this PR. OpenGL still stays as the default rendering pipeline and Metal rendering pipeline is optional to choose by providing MARKDOWN_HASH6fb3dbf166122f8049d99bbd64d48707MARKDOWNHASH.”
Pull request by Kevin Rushforth “Bump minimum JDK version for JavaFX to JDK” mentioned on the openjfx-dev mailinglist : “In order for JavaFX to be able to use more recent JDK features, we should increase the minimum version of the JDK that can run the latest JavaFX. Additionally, there is an ongoing cost to keeping JavaFX buildable and runnable on older versions of Java, and little reason to continue to do so. This continues our recent practice of setting the minimum JDK for JavaFX N to JDK N-2. JavaFX N is primarily intended for use with JDK N and we also build and test it against JDK N-1 (which is typically what we use as the boot JDK). Anything older than that, including the proposed minimum JDK N-2 (23 in this specific case), is untested. This PR targeted to JavaFX 25, and must not be backported to any earlier version.”

Long message by Sean Phillips on LinkedIn with a link to a video demonstrating near real-time 3D clustering of Deep Fake images in JavaFX : “… The video link above is an example of the Trinity XAI software demonstrating establishing a 3D clustering of Deep Fake imagery of human faces and automatically injecting new samples into the projection space (Auto-Projection). In this example the 3D clusters are established using a UMAP projection. The projection is frozen when auto projection is enabled so that new samples reuse the existing transform function achieved from the fit UMAP model. … Trinity XAI has cross platform binary builds here , as always, free and open source.”

Core

From the [email protected] mailing list: “The first Early Access (EA) build of JavaFX with the Windows Direct3D 12 rendering pipeline is now available . … At this stage D3D12 backend is feature-complete, however optimization and performance have not been the focus yet. There?s still a number of improvements and adjustments that must be made in order to match/surpass D3D backend. Notable areas known to us which need improvements are the 3D pipeline and cases where color blending is used - they will work but they will be (much) slower than D3D. Please keep that in mind when testing. … We look forward to your feedback.”

Autopo: An open source tool to automate .po file translation with AI.

Mon, 12 May 2025 07:12:39 +0000

As a developer today, you’ve almost certainly encountered the need of localizing your application or website. While setting up your project for internationalization is usually straightforward, managing translations over time can become a complex, time consuming and costly task, especially for open source projects.

Fortunately, machine translation have come a long way. It’s not perfect, but with the right context, modern AI can deliver surprisingly accurate results.

In this article , I’ll walk you through the journey that led me to create Autopo , a free and open source JavaFX desktop tool for managing .po files and with AI-powered features to translate and validate .po entries.

JavaFX Links of April 2025

Wed, 30 Apr 2025 10:06:10 +0000

Core

Slides from the presentation “JavaFX 24 and Beyond” by Kevin Rushforth at JavaOne, March 18th, 2025.
ApiDoc of JavaFX 24 is available on APIdia , a growing collection of high-quality APIdocs, interlinked, without tracking.
- Stefan Richthofer shares a screenshot : “APIdia JavaFX 24 docs do now include the incubating modules, but you have to adjust visibility settings to see them.”
Johan Vos on Mastodon : “_I’m still working on consolidation of JDK build with OpenJFX sources. Here is a post describing my progress and a suggestion . TLDR: I added a MARKDOWN_HASH04d3b60467c08e78fba0bc4a87592b9fMARKDOWNHASH configure option for the JDK. Key goal is not to make JDK build system harder to maintain. I’ll be honest about this. It’s hard work, requires diving into very different low-level things, and in the end, JavaFX developers won’t see anything from this work. But I believe I have to do this, as it is vital to JavaFX.”
- And continues : “I’ve spent way too much time trying to find an elegant approach in generating the JavaFX shader files with the existing gradle build, and copy the results into the OpenJDK fork that can build OpenJFX. Unless someone else wants/can do this, I will move that part to the OpenJDK logic as well. Should be easier. … I have to say that I’m slightly surprised that no other companies are helping me with this effort . I know at least 2 companies that distribute a JDK including OpenJFX mods. You would think they’d love this, but it’s very silent.”
The release notes for JavaFX 24.0.1 are being prepared in this pull request .
Chad Preisler shared some tips to distribute JavaFX apps :
- “_One excellent way to distribute JavaFX applications is to use jlink to build custom images. You can build for Linux, Windows, and Mac all on one machine without having all the host operating systems. The package is small, and you don’t need to install the JDK on each client._3
- “My JavaFX application bundle, built for MacOS X with jlink is just 41MB. I built the and bundled the app on Linux and ran it on OS X. No need to install Java on every client with a jlink image. I used JDK 24 to build the application.”
A tip by Wolfgang Weigend related to JEP 493 : “_Add JavaFX 24 to your jdk-24.jdk image with cmd jlink --add-modules javafx.base,javafx.controls,... --output image and verify file release and the directory MARKDOWN_HASH456c8dcb2e4cb13faea8318519ab5263MARKDOWNHASH.” (See the original message for the full command ).
Message from Gluon : “Another CPU release for JavaFX! Today, we released JavaFX 24.0.1, JavaFX 17.0.15 and JavaFX 21.0.7. Get it from gluonhq.com . Thanks to the fantastic JavaFX community for the combined work.”

SceneBuilder

SceneBuilder 24.0.0 is available. Highlights:
- Scene Builder Kit is now published to Maven Central, making it easier for developers to integrate it into their software.
- The Gluon controls, that are part of Scene Builder, were tightly coupled with Scene Builder Kit. Now those has been abstracted away into a pluggable component called Gluon Plugin.
- Scene Builder has been updated for full compatibility with the Java Platform Module System (JPMS).
- Logging to console is now enabled by default to make it easier to debug issues in Scene Builder.
- Multiple fixes went into Accordion, DialogPane, TextField etc. to make Scene Builder more robust.

Applications

Patrik Karlström released a new version of nbRsync : “A GUI for rsync, written in Java and JavaFX atop the netbeans platform. Available as appimage, snap, platform zips with and without a bundled JDK 24 .”
Serendipity released version 2 of SmartFinder : “Now with advanced filter building to create powerful, custom queries on file attributes and metadata. Stay tuned & level up your file search! " A video demo is available on YouTube .
JabRef received many GSOC proposals : “The team is now busy reviewing them. Meanwhile, our maintainer Dr. Oliver Kopp did a talk at the DANTE2025 (a TeXLaTeX conference) presenting the development process of JabRef and how users can test, provide feedback and participate in the community.
The slides (German only) from the talk are available online .”
An impressive combination of JavaFX and AI by William Antônio Siqueira : LLM FX, an LLM Desktop Client free for everyone !
- And he got some help: “A single contribution by Max Rydahl Andersen made LLM FX look much better and professional. Thank you so much, Max! In the video you can see it generating another report . Notice that the report is not well formatted because of my layout (it is a grid based layout, there’s a lot of room for improvements…”
Sean Phillips shared : “I made a major revamp update to Trinity XAI’s Readme . Added tons of content featuring the past year’s development of new tools with descriptions and images. "
- And a new video : “Demonstrating Trinity XAI’s ‘Hyperdrive’ importer to vectorize AI generated human faces using a locally hosted version of the CLIP multimodal embeddings model. Hyperdrive supports both images and text using a built in OpenAI API compatible REST client.”
Announced they are running on the latest JavaFX:
- LogoRRR . “Did you know, LogoRRR runs with the latest JavaFX version on windows, mac and linux! 🤗”
- JPro : “With JPro release 2025.2.0, we’ve added support for JavaFX 24 as well as improvements to Canvas shape clipping, instance startup timeout logging, and more.”
- SmartFinder : “SmartFinder runs on Java 24! Better performance and improved stability. Always one step ahead! SmartFiner is an alternative to MacOS Finder and Windows Search.”

Components, Libraries, Tools

Here you can find a list of all the Visual Studio Code extensions created by Hidekazu Kubota : “I have registered all the VSCode extensions I created for JavaFX in the Open VSX repository. Now, it’s possible to develop with JavaFX in VSCode-compatible editors like TheiaIDE.”

A new library by Alan Decunto : “Language Manager is a JavaFX library that enables dynamic language switching at runtime, allowing you to update the application language without needing to refresh the scene. “:
- 🌍 Support for multiple languages using standard .properties files.
- 🔄 Change language on the fly without reloading scenes.
- 🔗 Automatic binding for Label, Button, TextField, and other controls using @FXML ids.
- ⚙️ Custom annotations to ignore specific fields from auto-binding.
- 📦 Lightweight and easy to integrate.
TabShell is a lightweight platform for building tab-based applications in JavaFX using the MVVM pattern.
- Striking_Creme864 shared a video on Reddit : “For our project we needed users to be able to use a file chooser for file storages that may exist in the application, but not in the OS, such as Google Drive, FTP, etc. As a solution, such a custom file chooser was created, which recognizes 4 types of storage (floppy, CD, network and base). The file path is represented as a URI. Both modes (list/details) use VirtualFlow. File sorting is done by the table from details, even for the list mode (the table is not on the Scene). Storage implementations will be wrappers for OpenDAL, Commons FVS, etc.”

Podcasts, Videos, Books

Live stream step-by-step in Korean - with CC 😉 - by 알클 ALOHA CLASS in which he creates an application with SceneBuilder and FXML: JavaFX - Controller .
Frank Delporte interviewed Gerrit Grunwald (aka hansolo) for the JavaFX In Action series : “Gerrit created many JavaFX libraries and blog posts. I wanted to talk with him about his work with JavaFX, but I also learned more about SVGs and how the garbage collectors in the JVM are working, thanks to the amazing visualizations he creates with … JavaFX of course.”
Some feedback on this interview:
- By Matt Coley : “JavaFX has a perception problem. People will say ‘Why not Compose?’ before ‘Why not FX?’ even though Compose doesn’t have a functional context-menu component for desktop yet. Compose just has a much better PR department even though for desktop its a much lesser offering. FX needs a PR boost. To elaborate on the Compose remark, you can have a WindowScope MenuBar, but it’s only a wrapper that creates an un-styled Swing MenuBar. Additionally, generic compose context menus only allow text+onAction properties. For anything more the official docs tell you to use Swing’s JPopupMenu. The point being, an unfinished product for desktop application is given much more public praise over JavaFX due to the perceived ‘FX is dead’ problem. That’s the sorry state of things at the moment. I love FX and this makes my soul hurt.”
- By Catherine Edelveis : “Gerrit proves that Java is by no means a stranger in the world of UIs. I mean, all the cool libraries he’s built make me even more enthusiastic about my aspirations with #JavaFX. And I can see that I’ve only touched a tip of the iceberg by now 😁.”
- YouTube comment by Michel Antony Barros Barrios : “Amazing, I remember have used several components of Gerrit’s libraries to show data analytics about billing behavior in a project I work some years ago. His libraries are wonderful.”
Live stream with Dashaun Carter and Catherine Edelveis : “Who said that desktop apps are dead? We prove them wrong! 🥊 We explore the world of rich and smart GUI apps that combine the powers of JavaFX and SpringBoot.”

Interview with Abdoulaye Wade Cissé: Using a JavaFX application as a virtual chemistry and biology lab

Thu, 20 Mar 2025 13:46:59 +0000

I continuously collect JavaFX-related content for the JFX Central Links Of The Week . Recently, I saw a video on LinkedIn, shared by Abdoulaye Wade Cissé, of a JavaFX “virtual lab” and wanted to learn more about this project… Turns out he is a 22-year-old student in Senegal, creating a fantastic project to provide a virtual laboratory as software where the resources are not available for a physical lab. With his project, he proved that Java and JavaFX are the ideal way to generate entirely free software with a lot of functionality.

Here is the overview of the JavaFX LinksOfTheMonth of February 2025. You can find the weekly lists on jfx-central.com . Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via [email protected] .

Core

Early access builds of JavaFX that implement the new macOS Metal graphics rendering pipeline are now available. More info and link on Inside Java : “These EA builds are provided as a convenience, so users don’t have to build from the ‘metal’ branch of the openjdk/jfx-sandbox repository. The goal of these early access builds is to gather feedback as the team works on incorporating this feature into JavaFX. Feedback can be reported to the openjfx-dev mailing list.”
Two blog posts by Johan Vos :
- “Java Everywhere ” about how he sees the future of Java(FX) Mobile and building a competitor for Android and iOS with YouStore: “In this post, I’ll discuss my thoughts about a developer-driven approach to a store model, and since I am aware this is not a trivial thing to achieve, I lay out my second-best option, which is how to better support and maintain Java on mobile devices.”
- “Building OpenJFX using JDK ” about building different versions of OpenJDK for different platforms: “OpenJFX and OpenJDK/Mobile use a different build system. In an effort to simplify build complexity, and focus more on code, I am experimenting with using a single build system for OpenJFX and OpenJDK/Mobile. It turns out that the build system used by the JDK project does a great job for this.”

Applications

22-year-old student Abdoulaye Wade Cissé created a JavaFX application to provide a virtual chemistry and biology lab for students in Senegal, in schools where there is no budget for a real lab. Read more about it in this interview by Frank Delporte.
Özkan Pakdil 🦖 did some “shop-coding” : “I was in an Apple shop, took 30 minutes to install SDKMAN, GraalVM, Maven, and GNUtools to build Swaggerific and see it working. M3 16GB 16GB MacBook Air took 1 minute to compile the code 😄 latest graal 23.0.1 and it takes 4-5 minutes in my HP laptop, this apple tech is fast, I am intrigued.”
Gerrit Gruwald used his time on a plane very well: “Here is a screenshot of my little JavaFX version of ConfiCheck that I created on the flight to the US. As mentioned before it’s still missing some things but already not too bad 😁”

CheerpJ is a WebAssembly-based Java Virtual Machine for the browser. It can run games like Minecraft right in your browser . CheerpJ 3.1 got released and 4.0 is coming : “It’s a game-changer: Java 11+ support, WebAssembly-powered JNI (run native code, think Minecraft!), Full JavaFX & SWT, Improved mobile support. No plugins, just Java!” Definitely an interesting project to keep an eye on!
Johan Vos shares his frustrations… : “The biggest obstacles for running JavaFX on iOS is that I have to deal with Apple stuff that really makes me angry. I would accept this from an underfunded open-source project, or from Windows 95. But from a company that gets applauded for how user friendly it is, this is unacceptable. Stuck for 30 minutes in ‘100% completed’. Seriously, that is what makes it hard. Not the Java or C code.”
@mklestil is experimenting with JavaFX for 100DaysofCode : “Continued working on my Pomodoro app, SQLite is now running and storing Pomodoro sessions. Additionally, I have now learned how to use CSS in JavaFX, which makes the whole thing much more pleasant. Happy Coding.”
Navigating Common Challenges with JavaFX and JAR Files for Developers : “Discover essential tips to avoid common pitfalls when working with JavaFX and JAR files, ensuring a smoother development experience.”
Finally some good results with LLM, by ppolis : “Thanks to grok i just learned that i can you css in javafx , live is good.” 😉

Some JavaFX love…
- *Ada, neptunyl⁷-hydroxide : “I hate how nobody is bothered by the fact that peak cross platform UI framework design is JavaFX.”
- Kristin Rutenkolk : “As strange as it sounds, JavaFX is still surprisingly solid. It’s its own open source library OpenJFX now and there is a GUI SceneBuilder tool. It has it’s own declarative format thing going on if you want that. It feels quite oldschool but it’s robust and i still quite like it.”
- Benjamin Marwell ☕ : “I feel that JavaFX is so underrated and Java should be coming back to desktops…”

JavaFX Links of January 2025

Sat, 01 Feb 2025 16:20:33 +0000

Here is the first overview of the JavaFX LinksOfTheMonth for 2025. You can find the weekly lists on jfx-central.com .

Did we miss anything? Is there anything you want to have included in one of the next overviews?

Let us know via [email protected] .

Core

CPU (security) releases for OpenJFX are available. Read more on the Gluon website . You can get the SDKS here or use the Maven artifacts from Maven Central.
An early access build of the JavaFX from the “metal” branch of the openjdk/jfx-sandbox repository is available , implementing the new Metal graphics renderning pipeline for macOS: “The goal of this release is to solicit feedback as we work toward integrating this functionality into JavaFX. Binaries are provided as a convenience so that users do not need to build from the source code. Warning: This build is based on an incomplete version of JavaFX 25.”
Still running JavaFX 8 apps? As Oracle will end support for JavaFX on Java 8 in March 2025, Azul has put up a page to inform you about your options .
Johan Vos : “What if… we could build a JDK including JavaFX, using the JDK build system? As a POC, I added 3 javafx modules to my fork of openjdk/jdk and built them on Linux. The openjdk/jdk build system is excellent, and it required only minimal changes to do this. See GitHub .”

Applications

JabRef released the first 6.0 alpha version : “Packed with the cool features from GSOC and many other fixes: AI features, CSL Styles in LibreOffice, New search.”
Maksymilian announced the biggest update yet of his project Picture Comparer FX : “This application is designed to help you automatically find and manage redundant images in your collection. Whether you’re dealing with duplicate photos or just want a more organized image library, this tool simplifies the process.”
Brian Schlining shared a link to vars-annotation : “Video Annotation Application for MBARI’s Media Management (M3) software stack.”
Daryl shared a screenshot : “I haven’t posted an update in a while, so a sneaky peek at the latest version of Daric in development. It might look a little familiar… Why invent, when you can re-invent…” Daric is a modern BASIC dialect. It has a clean syntax, strong data structures, good library support and compiles to fast JVM bytecode.

Games

Almas Baim is continuing his experiments with shaders in FXGL and shared a lot of the results. Here are just a few, check his Twitter/X timeline for more…
- First public demo : “If you are on Windows and feel bored, give this demo a try and play with different shaders. If anything fails / crashes / doesn’t work, please report an issue on the main FXGL repo.”
- “There are some really cool shaders available online. Here’s one from shadertoy . The demo shows a property bound to a shader variable, hence the ability to control the rotation speed. The glass effect and reflections are just 🤩”
- “One of the use cases I envisaged for a combined JavaFX scene graph and OpenGL context . The majority of the game is rendered by JavaFX / FXGL, but some complex visual effects are done with OpenGL shaders. From performance point of view, this is also sensible.”
A video on LinkedIn by Almas Baim shows how he can move objects in an application with motion tracking: “Hand tracking via MediaPipe in FXGL is getting an upgrade in the next version. The demo consumes raw tracking data with no fine-tuning. So improved user experience results are certainly possible.”
Almas Baim shared a video : “Just a quick proof-of-concept demo running WebGL inside FXGL. Given native GLSL support is on its way, WebGL support is unlikely to reach production.”
A new Steam game: “SuperCowBoy is a 2D side-scrolling game developed using JavaFX. There are three professions in the game. The game is divided into 8 levels with gradually increasing difficulty, and the total game time is 20 hours. The game map is full scene, with a bright pixel art style high frame rate display.”
Mark J. Koch shared a video : “Scene working! Going to call this a wrap for now. Check out that cameo! Lots of future work to do here but it’s roughed out. Will pick another scene to work on over the weekend.”

Components, Libraries, Tools

Version 4.1.17 of Openglfx got released : “This library adds a new element to the JavaFX for rendering OpenGL graphics using LWJGL, JOGL, LWJGL2 or LibGDX. It is optimized for each platform and includes some auxiliary functions for working with OpenGL from JavaFX.”
Hugo Quinn released v1.0.0 of FxPopup : “JavaFX library that simplifies the creation of automatic forms and popup messages with minimal effort. With just a single line of code, developers can generate dynamic forms or display messages, while maintaining the flexibility to use custom views for both functionalities.”
Steve Hannah released jDeploy 4.0.34 : “It fixes ‘offline’ support for apps. If you have an app deployed with jDeploy , all you need to do is re-install your app for it to work fully offline.”

Podcasts, Videos, Books

Part 3 of the overview of the “JavaFX In Action” interviews by Frank Delporte got published on Foojay with:

- Jago de Vreede: SDKman UI, a user interface on top of SDKMAN for all platforms
Roberto Marquez published a video (with a link to the sources) “demonstrating a JavaFX application that communicates with a temperature and humidity sensor and displays the values on screen. It uses software from Frank Delporte (LED display) and jSerialComm, and hardware from Adafruit.”
Not from last week, but just discovered these now: Josh Long and Max Rydahl Andersen talk about JBang in a live stream and show how you can use it to run JavaFX code very easily.
An interview on LinkedIn with Stephen Chin , coauthor (along with James Weaver and Johan Vos ) of the Third Edition of “The Definitive Guide to Modern Java Clients with JavaFX: Cross-Platform Mobile and Cloud Development Updated for JavaFX 21 and 23”.
The first “JavaFX In Action” interview of 2025 is live! With Hydraulic Software, Mike Hearn solves a problem many developers struggle with: efficiently distributing your application and ensuring the users get the latest version. With Conveyor, he created a tool to easily create an installer for JavaFX, Electron, and Flutter apps! Check the blog for more info .

Conferences

The schedule has been published of JavaOne 2025 “Where Java developers come to skill up “, March 18–20, 2025, USA. It contains three JavaFX sessions:

- “Looking at Music, an experiment with Kotlin, JavaFX, MIDI, and Virtual Threads ”, presented by Vik and Frank Delporte.

Tutorials

Crystal Furman Sheldon published a challenge for students : “‘Twas the week before winter break when all through the school, the CS teachers wondered what interesting things they could do. The projects and exams were all set for the year, in the hopes of something fun to finish the year. JavaFX to the rescue a fun creative tool. Allow students to explore and learn something new…”
polypragmatist : “I came up with an interesting approach to create ‘Layout-centric’ styleable properties in JavaFX. Instead of creating a single-use named class, a small amount of setup makes it easy to create StyleableProperties on the fly for your layouts.”
Almas Baim published a video : “FXGL 25 Tutorial: Shaders. We go through a basic workflow related to using shaders in FXGL. As of December 2024, this only works on WIndows. Once the full release is ready, it will work on Mac/Linux.”
Kotlin for Desktop Applications: Using JFX and Swing : “In this comprehensive tutorial, we will explore the core concepts, implementation guide, and best practices for building desktop applications using Kotlin, JFX, and Swing.”
Webdox published a YouTube tutorial : “JavaFX GUI Tutorial for Beginners. In this video, you’ll learn how to set up a basic JavaFX project, create a simple user interface, and understand how to use JavaFX components like Buttons, Labels, and Scenes. Whether you’re new to Java or just getting started with JavaFX, this guide will help you build a solid foundation.”

Miscellaneous

Check the Twitter/X timeline of Divyanshu Yadav for more like this: “I’ve been using charts and graphs in JavaFX as a fun way to visualize how data manipulation algorithms work esp. sorting algorithms. Check out this GIF to see how the BubbleSort algo works.”
Some JavaFX love to start 2025:
- Rachid Laborantin : “And I thought Java was old-fashioned, but it continues to work wonders with JavaFx. I’ve been using Swing for a long time and I think it’s time to go to JavaFx.”
- Gerrit Grunwald : “Can’t say it often enough but JavaFX is sooooo good for creating desktop tools… simply love it 🫶🏻”
Johan Vos needs your feedback = “I’m working on StrangeFX, and looking for input from JavaFX developers. What would be your preferred root layout container for this concept? StrangeFX currently use a Group for this, but I am thinking about changing this, to improve embedding capabilities in e.g. JTaccuino.”
Article by Frank Delporte on TheServerSide: Swing vs. JavaFX: Compare Java GUI frameworks : “Yes, developers can use Java to develop graphical user interfaces (GUIs). In fact, Java’s ability to create cross-platform desktop apps was one of the language’s biggest selling features when it was released in 1995. However, as Java evolved and changed throughout the years, so did the desktop-rendering toolkits it supported, with the original Abstract Window Toolkit (AWT) giving way to Swing components which has now given way to JavaFX, the preferred choice for modern development.”
Peter Pilgrim on Bluesky : “Jasper Potts when he worked at Oracle had a lot of JavaOne demos including this JavaFX 3D container ports . Look at the H/W available today MacMini M4 then think of the possibilities, especially in Augmented Reality.”
Top Java Chart Libraries for Data Visualization in 2025 : “In this article, we explore some of the best free and open-source Java chart libraries available. Each of these libraries offers unique features that cater to different requirements, making them ideal for a wide range of applications.”
Max Rydahl Andersen published a blog post “about my side-project of implementing some sample MCP servers in Java using Quarkus and JBang. Connect to Any JDBC datasource, access the filesystem and draw art on a JavaFX canvas. Lets grow the list!”
Caroline Scharf wrote a long post : “Exploring Graph Node Visualization Techniques in JavaFX and Python.”

Core

A lot of updates by Johan Vos
- Weekend update : “Getting ready to create a developer preview for the headless platform.”
- An update on OpenJDK Mobile , a project to bring Java (and JavaFX) better and easier to mobile: “_Progress on using hotspot on iOS without AOT: building native JDK libs = ok, VM start = ok, Reading bytecodes = ok, Starting interpreter = work started. The reason I’m doing this with hotspot is that I only want to use code from OpenJDK. I need to 100% understand how the VM (e.g. hotspot) is doing its work. The docs in OpenJDK + JBS are extremely helpful and aligned with the JVM spec doc. Maintainability is a key asset in OpenJDK.”
- Headless JavaFX update : “First JavaFX headless builds are available for testing, see the mailinglist . Especially useful for JavaFX testing (and printing).”
- Building several versions : “JavaFX keeps moving forward! We’re now working on JavaFX 24, and JavaFX 17 and 21 are LTS releases, and so will JavaFX 25. No plans to drop support 🙂”
- Coding tip : “JavaFX Performance tip: do not use Platform.runLater() unless you’re sure it is required. The Runnables are executed on the same platform thread that is also doing the layout at 60 fps. I often see Platform.runLater() is used “just to make sure…” but that can slow down performance.”
Carl Dea shared : “JavaFX will have custom image loaders! See JDK-8343315 . Man I love JavaFX! Thank you, @jddarcy !”

SceneBuilder

Again Johan Vos 😉 : “Scene Builder is getting much better. Major changes in 24 are coming : A major technical debt has been addressed: the whole structure, including Scene Builder Kit, is now modular. I highly recommend creating your JavaFX interfaces with this RC release!”

Applications

Robert Ladstätter announced LogoRRR 24.5.1 for Windows, Mac, and Linux: “More information about the included features and bugfixes is available here .”
Bluerain announced Mago : “A JavaFX-based shell generator tool that creates payloads for Linux, Windows, and web systems. Generate payloads for various operating systems, Supports Base64 and URL encoding for generated commands, 110+ Payload. " You can find it on GitHub .
v3.20.1 of binjr, a standalone time series browser, is now available: “This is an interim release which fixes a regression introduced in v3.20.0 that severely impacts the performances of the CSV and Log files adapters. Read the full changelog and download it here . "
- Related to this release, Frederic Thevenet shared : “I’ve been pretty pleased with my custom ‘flickering neon sign’ effect in JavaFX for the binjr logo, until the moment I realized my 12 y/o had no idea what that flickering was supposed to be! A very ‘what’s the color of a TV tuned to a dead channel?’ moment…”
- If you want to stay informed about new binjr releases: subscribe to their RSS .
Gerrit Grunwald shared a video : “And here you go… my JavaFX-based QlockTwo with support for swipinp, on a Raspberry Pi.” He isn’t allowed to share the code because the design is copyrighted, but it is a piece of art to look at and a nice challenge to recreate it by yourself 😉
Jago de Vreede is looking for help : “I’ve created an early-access build for aarch64 binary for Mac of SKDman-UI. Unfortunately, I can’t test that one because I don’t have an M-MacBook. Does anyone with an M MacBook want to see if it works? "
- The (early-access) releases are on GitHub , including a version for x86 macOS.

Games

BJ Dela Cruz shared a screenshot of his “Wordle” application : “Finally, it will be able to generate an image that the player can keep to remember what moves he or she performed to win the game.”
Mark J. Koch : “One of my bucket list game projects has reached Alpha. I’m looking for enthusiasts to try it. I ported/re-engineered Neuromancer PC to JavaFX. Original content, all new engine. For now requires NetBeans IDE to run. " You can find it on GitHub .

Components, Libraries, Tools

Carl Dea published Cognitive 1.5.0 , a JavaFX MVVM forms library.
Check the wiki for new features .
Pedro Duke continues with his work in progress on the next release of Transit Theme and shared more screenshots:

- Part 11 : “New LIGHT and DARK styles for Editable ComboBox, Pill Buttons and Pill Toggle Buttons.”
- Part 12 : “New LIGHT and DARK styles for Editable ComboBox, Pill Buttons and Pill Toggle Buttons.”

Podcasts, Videos, Books

Not new, but just discovered: Chad Preisler uses a JavaFX UI to demo Kafka Outer Joins : “Make sure to stick around for the demo right around four and half minutes into the video . Happy coding!”
New “JFX In Action” interviews by Frank Delporte :
- Insights into a new open-source JavaFX project: Swaggerific. It’s created by Özkan Pakdil , who tells us more about this Postman alternative to interact with REST endpoints documented with a Swagger JSON. The video is on YouTube , and more info is provided in this blog post .
- Interview with Clément de Tastes : “In this episode, we take a look at the combination of JavaFX and Quarkus. Thanks to QuarkusFX , we can make use of the many advantages of the Quarkus system to create a desktop application.”
- Video #5 till #8 of these interviews got published in a summary on Foojay: Video series “JavaFX In Action”, Part 2 with Maciej Gorywoda about FxCalculator, Ramiro Domínguez Ayub about the Televic Generic Update Tool, Christoph Schwentker about JabRef, and Ulas Ergin about migrating from Swing to React UIs, all combined in one Java(FX) app.
Anton Arhipov has a box with books to review : “I was helping with technical reviews of this edition. The author Faisal Islam teaches Kotlin by explaining and visualizing various algorithms. They used JavaFX for visualization though and I’d love to see another edition of this book using Compose instead.” Let’s conclude the Faisal made the right choice and Anton is wrong 😉

Tutorials

Alexander S. Ricciardi shared a tutorial about JavaFX Layout Managers : “This article explores how Layout Managers provide an abstraction that streamlines the development of Graphical User Interfaces (GUIs) in JavaFX by automating component sizing and positioning. Using predefined layouts like HBox, VBox, and GridPane, developers can create organized and responsive interfaces.”
polypragmatist shared on Bluesky : “Looking to learn JavaFX? Take a look at my Beginners’ Guide to JavaFX . It’s a 13-part tutorial that takes you from ‘Hello World’ to building an Reactive GUI with a framework. No FXML, all the layouts are done in code.”
Tutorial by Codez Up:
- “Building a Social Media Dashboard with JavaFX .”
- “Unlock Efficient Cloud and Edge Computing with JavaFX Websocket Services ”, to create a JavaFX application that uses Websocket Services to communicate with a server.

Miscellaneous

On Bluesky, Gerrit Gruwald explains that the visuals of his Devoxx presentation are created with JavaFX.
You can read more about JavaFX Nodes versus Canvas experiments by Frank Delporte in the German JavaMagazin edition 12.2024 .
Sean Phillips shared on LinkedIn : “Applying 3D Projected Volumetric Detection method to the Biden Robocall Deep Fake. … Caveats to this demonstration are that this was clearly a controlled experiment and importantly is a qualitative manual process. However it is clear the potential of the method and with sufficient further development could be largely automated.”
JVM Weekly vol. 106 by Artur Skowroński has a section “What Does Java UI Development Look Like in 2024?” which includes, of course, JavaFX:
- “How could we skip JavaFX, especially with a new and interesting application in this technology?”
- “JTaccuino is a notebook developed for Java programmers, allowing users to interactively experiment with code.”
- “The DeepNets project, which is a reference implementation of JSR 381, recently boasted new tooling enhancements .”
saige! shared on Bluesky : “I made a little animation in JavaFX. Gonna try and convince my group that we should use it for our project as a loading screen.”
Anthony Goubard shared a screenshot : “New in the IDE plugin ‘Applet Runner’: JavaFXApplet and SceneApplet classes to run a JavaFX application (or scene) embedded in your IDE. See the demo of TilesFX from Gerrit Grunwald running in IntelliJ IDEA.”
You want to find even more “JavaFX Goodies” than you can find on JFX Central? Head over to the AwesomeJavaFX repository on GitHub , started by Hossein Rimaz and extended by many others .
JPro, bringing Java to the browser , is following the Java “release train”: “As of JPro 2024.4, JavaFX 23 is now supported and set as the default version. Browser tabs now reflect the JavaFX stage’s title and favicon, and more! Catch up on the latest updates here .”
A video by OrangoMango : “The start of a new project: Mandelbrot set visualization. Still not perfect, it has some small issues. 🙂”
Jonathan Mark Mwigo shared a screenshot : “JavaFX Modern Sales ERP Dashboard. Excited to see it go live! 🚀💻”
polypragmatist is very active promoting JavaFX on Bluesky , for instance: “JavaFX is 100% a reactive declarative UI development library. No FXML required. The Observables facility is tightly integrated into the UI components and makes React look clunky in comparison. Last I looked, Java supported loops and conditionals. JavaFX works great with Kotlin too.”
Johan Vos is testing bld to replace Maven : “Did a first project using bld. Works great, and I love the ’no auto-magical behavior’. I need a deeper look to see how to deal with platform-specific jars at runtime, e.g. JavaFX, where we currently use a maven plugin to deal with this.”

JFX Central

JFX Central is now also on Bluesky: @jfxcentral.com
Message from Dirk Lemmermann : “JFX Central is now available as a web app, a desktop app, and an iOS application (via Gluon). We still need to get it into the Google Play Store. Anyone up for the job? If any code changes are required I could work on that. I just need somebody to take over the deployment part to the Play Store. I do not feel at home at all in the Android space 🙂”

Core

Message from Kevin Rushforth in the [email protected] mailing list that shows how OpenJDK and OpenJFX keep being aligned thanks to the 6-months release cycle: “I propose to remove support for running JavaFX applications with a security manager in JavaFX 24. Any JavaFX application that uses a security manager will necessarily need to use JDK 21.x LTS going forward, and thus can similarly use JavaFX 21.x LTS. "
- See JDK-8341090 : “The Java Security Manager was deprecated for removal in JDK 17 by JEP 411 .”
Artur Skowronski highlights in his JVM Weekly newsletter some JavaFX facts:
- JavaFX 23 announced by Kevin Rushforth has hit the scene and brought with it a warning: “It’s time to update.” JavaFX has dropped support for older versions and will now require JDK 21.
- Oracle has announced that support for JavaFX in JDK 8 , the last version they released, will end in March next year.
SamFx happily announced the merge of his first pull request into the OpenJFX code to fix “Push Notification fails on Android when app closed.”
Just a tip: keep an eye on github.com/openjdk/mobile . It’s a project to bring more mobile support to the OpenJDK. This will, once integrated, make it easier to support JavaFX on even more (mobile) platforms.
In an article on The New Stack, “End of the Road for JavaFX in JDK 8: Keeping Your Apps Alive” , Frank Delporte alerts users of Oracle Java 8 builds with OpenJFX: “From April 2025 and onward, if you are using JavaFX, you need to find an alternative distribution if you’d like to continue to receive security updates. "

Azul Brings Java from Edge to Cloud

Fri, 27 Sep 2024 11:30:22 +0000

In Part 1 of this series, “A Fresh Look at Embedded Java ,” we explored the use of Java for embedded use cases.

Azul and its Zulu Build of OpenJDK (Zulu) are the ideal partners in this part of the software world.

Let’s expand and look at the cloud part of a typical end-to-end solution with sensors, edge devices, client applications, and cloud services.

Azul Platform Core for edge devices and client applications

Because Java delivers fast development speed thanks to its amazing methods and tools and its impressive performance in handling massive amounts of data, it’s the ideal programming language for building applications for edge devices that collect data from various sensors.

Running JavaFX applications on ARM with Azul Zulu

Thu, 22 Aug 2024 08:51:57 +0000

Since the April release of Azul Zulu Builds of OpenJDK, packages with JavaFX support for ARM 64-bit systems have been available.

As ARM processors are the “core” of most embedded systems, these runtimes provide the additional benefit of bringing user interface development into the Java space. Having your full code base, from server to end device, based on the same Java code and dependencies, brings many improvements in total cost, development approach, and test and deployment strategies.

JavaFX Nodes versus Canvas

Wed, 07 Aug 2024 08:22:31 +0000

Recently I was working on an article about Azul Zulu with JavaFX support for ARM systems, like the Raspberry Pi. As you can see in this video , I found out my little test application with a lot of “bouncing balls” started losing performance on the Raspberry Pi with more than 1000 of those balls.

Of course, having that high number of visual components in a typical JavaFX user interface would be a badly designed application. Imagine a long registration form with that number of input fields and labels… it would drive your users crazy.

JavaFX Links of July 2024

Patrik Karlström shared screenshots : “Bringing back the cron like scheduler to my JavaFX based rsync gui. Converting the old swing cron dialog was much less work than expected. JavaFX really do have nice things to offer!”
Datacollie, the SQL UI by Xiong Chun looks more-and-more impressive : “The paging model of the SQL query result is determined, and a toolbar is added to the result table.”

Games

5kovic made Tetris : “Music and background found on Google, links in comment section.”
Mark J Koch is reverse engineering the “Game of the Year” from 1989 : “Screen grab of browsing the sprites extracted from the Neuromancer PC .DAT files. They are stored as indexed color, RLE and Huffman encoded blobs of data. I wrote some Java code to extract/decompress/decode them from the file and write them to a ‘cache’ directory as PNG files. The game came on two floppies and is still one of my favorites and I play it in a DOS emulator from time to time.”
OrangoMango made a game in 24h for the indiedevgamejam : “Escape and drive on the highway as long as you can. By driving on the 2 leftmost lanes you get double score as well as driving fast.” You can play it on orangomango.itch.io/milkywayescape .

Components, Libraries, Tools

Pedro Duke shared a video : “A bunch of changes coming to Transit Theme… One of them is that if you change it to Dark style it will also change the Window frame of where the theme is applied. (JavaFX always shows the Window frame in light color)”
- And Pedro published a new post: “Transit Version 2.0 Released” : “Styles work as User Agent Stylesheets like Modena (much easier to override) + True Dark Mode (Window frame also changes when set to Dark style).”
Dirk Lemmermann shared a screenshot of an implementation of the FlexGanttFX library : “We use it in our energy CRM system to visualise the consumption data provided by the home-installed electricity smart meters of our customers.

YouTube Shorts by OrangoMango :
- Falling sand with JavaFX
- Conway’s Game Of Life implementation in Java and JavaFX

Tutorials

On dev.to, Paul Ngugi is publishing a blog series of JavaFX tutorials .

Miscellaneous

Mark Fortner replies to a message by Justin Fagnani about Flutter : “It’s always interesting watching people re-invent the future. JavaFX has all of the features that you describe. Scenegraphs, multilanguage support, compiles to WASM, CSS. I think it really boils down to one’s willingness to get out of one’s comfort stack.”
A new video by Christopher Schnick : “The JavaFX 22 platform preferences API in action with native window themes on Windows 11.”
- Christopher also reports : “Seems like JavaFX applications run fine on Windows ARM systems through the x86_64 compatibility layer.”
Gerrit Grunwald shared a screenshot of a private project (“sorry not allowed to share…”) which recreates the QLOCKTWO in JavaFX.

Book review: Frontend Development with JavaFX and Kotlin

Fri, 14 Jun 2024 09:06:53 +0000

For a personal pet project, I started experimenting with JavaFX and Kotlin to create a user interface with a lot of Java / Kotlin background processing. As I knew there is a book available on this specific topic, Apress was so kind to send me a review copy of Frontend Development with JavaFX and Kotlin: Build State-of-the-Art Kotlin GUI Applications by Peter Späth (152 pages, 48€ on paper, 35.5€ for ebook on Amazon.nl).

JavaFX Links of May 2024

Sat, 01 Jun 2024 08:12:12 +0000

Here is the overview of the JavaFX LinksOfTheMonth of May 2024, published on jfx-central.com during this month.

Core

When Johan Vos shares his notes , you may want to keep on eye on them…: “While working on Java on Mobile, I keep my notes here (best viewed with lynx). This is not user/developer documentation, but people interested/familiar with OpenJDK building might keep an eye to see how far we are.”
Nice visualization by afoo to illustrate the flow of event phases (capturing with EventFilter versus bubbling with EventHandler) in JavaFX.

Applications

Robert Ladstätter announced a new release of LogoRRR : “This update is a maintenance release with visual improvements and bugfixes. Internally, substiantial work was done to improve test coverage (End2End tests and performance tests).”
- And a video shows a new viewport visualisation of the current visible text in the box view on the left.
- And did you know you can play Snake with your logs ?!
Sean Phillips is on a roll again with a Twitter Thread with a lot of amazing 3D data visualizations.
- “Hi res Lunar elevation scans combined with hi res color spectrum imagery (100m accuracy). Working on an easy to use Line Of Sight viz for Lunar surface assets. Mixing JavaFX and the NASA WorldWind Java SDK is a very powerful combination!”
- “Borrowing from Worldwind’s Line of Sight example I integrated a JavaFX point & click tool with hi res lunar elevation data/terrain . Upgraded the computations to run using #Java parallel streams. 100 LOS checks computed/rendered < 1 second. Developed in a weekend.”
- “Extended the lunar LOS tool by several orders of magnitude to check for performance . 10k LOS checks, 30k 3D artifacts added to the scene: 244 ms (including the rendering)… on a decent laptop. But Java is slow and JavaFX sucks and all those other foolish things you hear…”

Run JavaFX on the Windows Subsystem for Linux and More!

Tue, 12 Mar 2024 16:11:56 +0000

What does it take to run standalone JavaFX applications on exotic Linux systems like the Windows Subsystem for Linux or some embedded systems? As you will see, not a lot! Familiarizing yourself with the native libraries required by JavaFX and the font loading process is all that is needed. Then, JavaFX applications can run on them out of the box if you set everything up correctly.

Most graphical Linux systems will automatically come with all the native libraries that are required by Java(FX) as these are pretty standard. Running a standalone Java(FX) application, which has been created with jlink or jpackage for example, on these systems works without having to put in any thought about possible dependencies. However, there are systems where this is not the case.

JavaFX Links of February 2024

Highlights from the openjfx-dev mailing list

Version 23 will bump the minimum version of the JDK needed to run JavaFX to JDK 21 .
A new feature is proposed: RichTextArea . “Intended to bridge the functional gap with Swing and its StyledEditorKit/JEditorPane. The main design goal is to provide a control that is complete enough to be useful out-of-the box, as well as open to extension by the application developers. We are looking for feedback, and will update the proposal based on the suggestions we receive from the community.”
Johan Vos shared the following message: “I created a branch in the jfx-sandbox repository for experimenting with a headless glass platform. This addresses JDK-8324941 where I suggest a POC for a Headless platform. There are a number of use cases for this, including:
- Applications that require JavaFX rendering without presenting this to a window (and instead send it to a printer for example).
- Running tests without requiring a window manager.”

Applications

Amit Kumar Mondal announced OSGi.fx v2.4.4 : “Packed with enhancements, integrating Java 21 and JavaFX 21 seamlessly.” OSGi.fx is an easy-to-use desktop application to manage OSGi frameworks remotely. You can find the release notes on GitHub .

JFX Central

Webswing got listed in the tools section . It’s a web server that allows you to run your (old) Swing, JavaFX, NetBeans or Applet application inside your web browser in a blink of an eye. They posted a nice shoutout to JFX Central on Twitter/X .
Available soon: new detailed icon page where you can find out everything there is to know about the icon, e.g. the Ikonli “literal” (code), the CSS rule, the Java code required, the maven / gradle dependency, the SVG path, and so on. The main reason for having this detail page is so that you can send a URL to somebody else pointing directly at a specific icon and all of its info.
All the JFX Central Links Of The Week of January got posted on Foojay.io , the website for Friends Of OpenJDK.

Achieving High Throughput Without Sacrificing Latency

Fri, 02 Feb 2024 09:39:47 +0000

Latency and Throughput

In discussions on performance, it is common to encounter the terms Latency and Throughput to describe the characteristics of a software component.

We can define these terms as follows:

Latency is a measure of the time taken for one thing to occur. For example, it could be the time taken to respond to a change in the price of a financial instrument that could influence the decision on whether to buy, or sell. It could be the time taken for a component monitoring some external device to respond to an indication of a change in the status of that device (like a change in temperature reported from a thermometer).

- And he found out that: “team JavaFX is now right in the middle of JVM game projects on the 1st page of GitHub search with 3960 stars! Since FXGL is now 49.4% #Kotlin and 49.1% #Java, I had to cheat and include both language: Java, language: Kotlin in the search .”
Max Rydahl Andersen wants to collaborate with Almas to make FXGL and game development easier with JBang: “I’m happy to help to make FXGL example games “jbang friendly” … there are lots of ways we can do that.”
New video update by London Softworks : “Trying my best to work every day, so many exciting things to come in the near future! For now, enjoy a small demo of a few components (Texture, Mesh, Transformation) being fully implemented!”
Beta preview by Hlan Htet Kyaw of Brain Buster : “Please test and provide feedback. Any help would be appreciated.”

Components, Libraries, Tools

Steve Hannah published a new IntelliJ Plugin for jDeploy to create a new desktop app with automated releases on GitHub in under 2 minutes: “In addition to creating the project locally, the wizard will create a new GitHub repository, that is set up to generate new releases on every commit. Within 30 seconds of creating your project, you should be able to download and install the app from GitHub releases.”
- He also shared a GitHub project as a showcase for jDeploy: Sample FXGL project deployed with jDeploy via GitHub releases .
Michael Gasche shared a showcase of a rapid development framework on the Foojay Slack with some out-of-the-box functionalities (installer, licensing/registering, app-config, update-checks, some further dialogs) for Java FX UI apps: “It has default views which can be used with a one-liner to show an HTML page, license dialog, or other content that can be switched off per platform, e.g. because the Windows installer already has one. The Registration module in the demo is a “dummy” as it is quite big and advanced and possibly involves a server.”
Laurent Bourgès reached the milestone of +125,000 downloads of his Marlin Renderer : “An open source (GPL2 + CP) Java2D RenderingEngine optimized for performance (improved memory usage (~ no GC) and footprint, better multi-threading) and better visual quality based on OpenJDK’s Pisces implementation.” And he adds: “Enjoy FOSS & see you at FOSDEM24 ”.
Carl Dea shared a video : “JavaFX with the native background blurring effect on the MacOS is now working! Thanks to Steve Hannah for the tremendous help in understanding the native side (MacOS). Demo here . Eventually will end up in Pedro Duque Vieira ’s FXThemes project. I also want to give a shout-out to the amazing software engineer Martin Fox (a JavaFX contributor).”
Pedro Duque Vieira is asking for help testing out FXThemes : “If you have a machine running Windows 10 can you run the fxthemes-samples subproject and tell me if the window that shows up has a background blur? The project is using Java17 for now…”

Controlling LED Strips with Java and JBang

Mon, 22 Jan 2024 18:08:51 +0000

One of the most “fancy” electronic components is definitely… a LED strip. It’s really cool to control a long strip of lights with only a few lines of code.

But, there is a problem. The timing of the signals is crucial to reliably control these strips. Both Python and Java on a Raspberry Pi can struggle with these timings as they are running on Linux, a non-real-time operating system.

So, for instance, pauses in the garbage collection of the Java virtual machine, or any glitch in the operating system can cause unexpected effects on the LED strips. That’s why in most projects, a microcontroller (Arduino, Raspberry Pi Pico, ESP32,…) is used to drive the LED strip.

JavaFX Links of December 2023

Sat, 30 Dec 2023 13:11:51 +0000

This is the final JavaFX LinksOfTheMonth review for 2023.

It was an amazing year with many evolutions in Java and JavaFX and a complete “fresh” version of JFX Central.

Thanks for following these updates and looking forward to more of your JavaFX work in the new year…

This is the overview of the LinksOfTheWeek that got published on jfx-central.com during December.

Core

JavaFX 22 Early-Access Builds, Build 19 (2023/11/24), is available on jdk.java.net/javafx22 .
- Issues addressed in Build 18 and Build 19 .
- JavaFX 22-ea is designed to work with JDK 22-ea, but it is known to work with JDK 17 and later versions.
Dirk Lemmermann is happy with a pull request in OpenJFX “that finally adds styling support to the fitWidth / fitHeight / preserveRatio / smooth properties of the ImageView class. I always wondered why they were missing. Turns out they were simply forgotten (but a TODO was in the source code :-)).”
A little insight into the OpenJFX project by Johan Vos : “We often get requests about ‘Why don’t you provide a JavaFX build for this or that platform?’ The short answer: it’s easy to create a one-time build with some parameters, but it’s hard to maintain. And expensive. Our AWS bill is impressive. And since all our OpenJFX builds are available for free, this is really a major cost for us.”

Applications

RNArtist is doing amazing user interface work… This is only one of his recent messages : “If the RNA 2D layout selected at first doesn’t fit your needs, RNArtist will provide you a new panel to compute and preview alternate layouts.”
An impressive and super-smooth first timeline management demo of the personal After Effects app by Alessio Vinerbi .
- A video by Alessio Vinerbi introducing the first time interpolation demo of MoonsonFX, his personal After Effects written entirely in JavaFX.
- A new teaser video by Alessio Vinerbi of MoonsonFX , a JavaFX animation tool.
Donald Raab uses the Jackson library to persist his JavaFX ToDo List to JSON .
Divyanshu Yadav is working on a weather app: “Dear Web Devs! JavaFX is also in the race!!” .
Heshan Kariyawasam shared some nice projects again!
- A JavaFX-based statistical calculator : “Quickly compute mean, median, mode, and variance with an intuitive user interface.”
- A Dynamic Background Demo that dynamically adjusts the background image to fit the screen dimensions. It utilizes JavaFX’s Stage and ImageView components to create a responsive background. The app also includes functionality to open a new window, demonstrating basic window management in JavaFX. The video shows a cool use of multiple windows in one application.
- And on Foojay.io, his first blog was published: Creating Executables For JavaFX Applications : “Let’s take a look in this article at the current state of what can be done with jpackage and GitHub Actions to create executables for JavaFX applications.”
Patrik Karlström is updating rsync GUI, an application he wrote in 2015 : “Today I ran my first #backup with the next version based on NetBeans Platform and JavaFX. Still very rough around the edges though.”

Games

Almas Baim is working on new features for FXGL:
- “The current version of the FXGL engine can only show up to 5 dialogue options. The next version will use a scroll bar, where needed, to show any number of options, as can be seen in the demo .”
- “Adding NPCs that can act as companions somehow instantly makes it more interesting to explore the world .”
- Almas Baim shared a new proof-of-concept of the node inspector panel in FXGL, which allows editing various node properties: “This way each dialogue node in the main UI just captures the text associated with it and reduces visual clutter”.
OrangoMango published a trailer of RailTheWay on YouTube : “A game made in Java/JavaFX without the use of any game engine. Guide the trains to their station. Each train has a color that represents its destination. Sometimes there are some cargo trains that disturb you, try to let them go away and be sure to avoid the cars on your way!”
Sulaimon Muhammad shared a brief video of the “Who Wants to Be a Millionaire” game developed using JavaFX and Hibernate: “Exciting things happening with Java!”
London Softworks is building a custom 2D game engine in Java and shares the progress in various tweets.
Frank Delporte published “A JavaFX Game Application in a Single Java File with JBang and FXGL” . A video walk-through together with Almas Baim will follow soon…

Java for desktop applications: Tips and Tricks (Part 1)

Fri, 24 Nov 2023 09:18:15 +0000

As desktop applications have kind of become a niche topic, it’s getting harder to find information about up-to-date best practices for desktop development.

Since I have been doing this for many years now, I hope that I can share some of the lessons learned with other fellow desktop developers. Most items that are discussed here are taken straight from XPipe , the application I am working on right now. So if you’re skeptical or are interested in more details, you can take a look at the actual source code or try them in action yourself in the actual application.

JavaFX Links of October 2023

Tue, 31 Oct 2023 13:04:32 +0000

Thanks to the Devoxx conference, there are many hours you can spend on JavaFX-related videos!

But as every month, there is a lot more to read and learn about JavaFX…

Have fun with this overview of the “JavaFX LinksOfTheWeek” that got published on jfx-central.com during October.

Core

Last month Java and JavaFX 21 were released. And Johan Vos already had an update : “JavaFX 22-ea+11 has just been released to maven central (and on gluonhq.com/products/javafx ). This contains the much anticipated memory improvements :)”
- “This contains a major change in some CSS processing, see this commit by John Hendrikx , that leads to improved performance (less GC). Please test and evaluate.”
Kevin Rushforth and Johan Vos had a BOF at Devoxx in Antwerp.
- During this BOF, some of the new features that could be included in JavaFX 22 were presented:
- Platform APIs
- (unlikely) CSS theming
- InputMap/Behavior
- Feedback was asked from the users regarding blocking issues in JavaFX itself to be able to build more amazing stuff:
- Removal of remaining AWT dependencies.
- Full integration with the desktop (alerts, dark/light,…).
- Missing 3D point and line drawing methods.
JavaFX 21.0.1 and JavaFX 17.0.9 are now available for download from the Gluon website and from Maven Central. “Enjoy Java on the client! ”.

Applications

At Devoxx we got blown away by the demos given by Florian Enner to visualize robot arms and interact with them. He wasn’t a speaker at the conference, but we sure hope he will be next year or on any other conference. Make sure to check out of few of his videos…
- JavaFX w/ GraalVM native image (Windows) : a desktop application with charts and controls, but a robot simulated in 3D.
- JavaFX: migrating to AtlantaFX themes : migrating from a custom JavaFX design to AtlantaFX themes. And even more 3D robots and charts!!!
- JavaFX 3D: Dynamic CubeWorld : 3D cubes, a loooooot of cubes…
- And these are all his YouTube videos .
The Hero app by Pedro Duque Vieira has an alert/error system where the button will show as filled whenever there’s an error/alert : “This immediately warns u in a subtle way that u may have things to fix. After you’ve fixed everything the alert button shows up empty.”
- He also shared more info and a video about Visual Styles in HERO : “It allows the user to see properties of his CAD project quickly, at a glance.”
RNArtist has been updated , mainly to run on Windows. Releases 1.0.8 and 1.0.9 are available (just restart RNArtist). 1.0.9 will just increase the maximum memory to be used (needed for Windows).
- Nice new screenshot by RNArtist showing: “Insight into a random RNA 2D with a size of 1kb and a pairing density of 60%. Bracket notation with colored helices in the lower part. Simple rendering of the 2D plot in the upper part.”.
- Here you can find a picture to summarize the new workflow that will be in RNArtist 1.1.0.
- And he shared a blog post: Visualize experimental data on your RNA 2D .
Clemens Lanthaler release V1.3.3 of Photoslide , a simple photo management application with a modern and reactive user interface. This version brings updates to JavaFX 21/JDK21 and fixes to the filter module: “Thanks to FXGL examples the filters are now realtime and therefore I can now start implementing more filters and the edit module”.
Tobias Briones is working on Building Slides from Screenshots App in JavaFX: “A great title where I granularly blogged the development of a powerful JavaFX desktop app” .
- And he has a “JavaFX app that uses Tesseract OCR to detect words in the slide images, allowing users to underline them accurately” .
OrangoMango shared a video showing his logic simulator app . More info, link to the sources and browser version can be found on orangomango.itch.io/logicsimulator .

Components, Libraries, Tools

A new library announcement by Pedro Duque Vieira, FXThemes : “It is a Java library that contains classes to help in advanced JavaFX theme development. Right now, it contains helper classes to change the appearance of a native window frame as well as the backdrop of JavaFX native Windows.” The announcement page also contains more info about the reason of providing this functionality in a new library.
- True Dark Mode on Windows10 will be available soon in a new release of FXThemes : “Win10 is the most used Windows version (Windows being the most used OS). This was a pain to implement. Native code is different from win11. On win10 this API is undocumented.”
GemsFX 1.82.0 by Dirk Lemmermann with:
- Early access version of a TreeNodeView with many configuration options (added by LeeWyatt )
- Gives you controls / pickers for: choosing a date, choosing a date range, choosing a month, choosing a year, choosing a time, choosing a duration.

Tutorials

Please keep an eye on Edward Nyirenda Jr ’s website as he keeps on giving! For instance, “JavaFX with Gradle” was published this month.

Miscellaneous

Pedro Duque Vieira shares a video to illustrate that a JavaFX scene graph can handle a lot of nodes: “The view on the left is using retained mode rendering. There are more than 1k nodes visible at a time and yet without major optimizations it runs fine. Tip: No need to rush to a Canvas implementation (immediate mode).”
Impressive 3D results by OrangoMango , considering he is running it on a Raspberry Pi: “If I render the triangles, the application runs at 5 fps.” .
Homebookner shared a link to an interesting project by Sheikah45 : FX2J - FXML to Java Builder : a post-processor that converts fxml files into Java builder source files.
Christopher Schnick reported some issues on new gnome-based desktops , e.g. on Ubuntu 23: “For the JavaFX devs who use the system tray, note that there are various GTK issues. If you are using FXTrayIcon, your app will freeze.”

Navigating Behaviour with Events

Wed, 25 Oct 2023 15:04:35 +0000

Two Approaches

There’s little doubt that modern software architectures lean towards asynchronous models for communication between distributed components (where “distributed” means components that are not part of the same process, be they on the same or on different physical machines). Synchronous models such as Remote Procedure Call (RPC) are now largely discredited [Waldo , Vinoski ]; even asynchronous variants of these are not seen as desirable.

When we strip away the layers that present the illusion that RPC is really just the same as Local Procedure Call (i.e. a normal method invocation), we find sitting above the transport some form of messaging protocol. And these days, the APIs seem more willing to expose developers to these lower-level details, making it clear to programmers that communication with a remote component is inherently more complex than making a simple procedure call.

Mon, 16 Oct 2023 07:16:57 +0000

The first week of October, the 20th edition of Devoxx took place in Antwerp, Belgium.

Over 3000 Java developers, speakers, and enthusiasts gathered to share their knowledge and learn from each other.

I got the opportunity to walk around with a microphone and talk to visitors and speakers.

Not all of them, as there were just too many people and too many exciting sessions happening simultaneously.

- JavaFX 22-ea is designed to work with JDK 22-ea, but it is known to work with JDK 17 and later versions.
- Dirk Lemmermann is experimenting with 22-ea+9 : “Showing correct bold text on macOS and much lower initial memory consumption in our CRM software”.
A message by Johan Vos : “One of the great (non-technical) things about JavaFX is that it is not owned by a single company that tries to use it for its business strategy (e.g. like Google does with most of their “free” stuff). It is really the wide JavaFX ecosystem that drives JavaFX forward, and that allows for pure and honest innovation.”

Applications

Onkel Stipe shared a screenshot of SoundLab : “I developed it to investigate in generating realtime virtual analog sounds. The Oscilloscope feels quite analog. It also has a realtime spectrum and a view called “klangteppich”, which nicely imitates the spectral view of audacity.”
WhiteWoodCity is upgrading dillon-boot-fx, a Permission Management System UI , to JDK 17+ and also providing jigsaw support.
Fx Calculator by Maciek Gorywoda is now available at Google Play Store ! “Written in Scala 3, JavaFX, and built with GraalVM Native Image”
The next version of JDKMon, the tool to keep your Java installations up-to-date, will now also show you the dates of the next OpenJDK update and the next OpenJDK release, says Gerrit Grunwald .
JabRef is using Java 21 for their new release 5.10 .
The Logic simulator by OrangoMango got updated to v1.1 update : “A new web version made with WebFX, bug fix, RGB lights and some UI changes.”
surajit completed M-AID (Retail Pharmacy Management) : “With a mobile app that is always connected to the desktop app via Wi-Fi, no internet is needed for operations.”
RNArtist by Fabrice Jossinet offers now an undo/redo feature : “It can even iterate automatically over its history. Take a look at my attempt to produce a better layout for an archaea LSU rRNA (green blinking = redo, orange = undo).”
Biometrics Engineer shared a video showing a “JavaFX Linux Biometric Time and Attendance - Staff Registration DEMO that is implemented on Ubuntu Linux using ARATEK A600 Biometric Fingerprint Scanner.”
RNArtist is announcing : “Installers will be available next week. Thanks to the very good tool JDeploy, you will automatically get the latest version after each launch of RNArtist. Now it’s time to write some documentation…”
- And shared screenshots of the tool 3 years ago versus now , with some very nice comments and links to the project in the thread.
- BTW, as someone pointed out, you can maybe use this tool to design airport terminals… 😉
Sean Phillips is using Trinity for : “Detecting ChatGTP generated medium size text blocks using manifold approximation, polyhedral volume techniques and JavaFX 3D. Sorry not sorry bad guys.”
- And Apple M2 silicon (Arm64) builds now supported through Trinity’s GitHub Actions thanks to the magnificent CI work of samypr100!
Malik Hamida is working on a micro banking system project
Eltayeb Ibrahim created a user-friendly Product Management System using JavaFX for the frontend and Node.js with Express.js framework for the backend.
Heshan Thenura Kariyawasam made a File Shredder app and shared the sources.

OrangoMango announces “Chess 2.0 is finally complete” : “The WebFX version is now available at orangomango.itch.io/chess . Play single player against stockfish. Play multiplayer against a friend in LAN or on the server.”
Always fun when Almas Baim shares one of his experiments with FXGL : “… and in this episode of how to inefficiently clear the screen …”
Ahmed Bakr completed a Tic Tac Toe Game with Tiva C and JavaFX : “Our primary goal in undertaking this project was to explore the integration of microcontrollers with high-powered processing computers to tackle tasks beyond the capabilities of a standalone microcontroller.”
WhiteWoodCity made his game demo and self-made game utilities fully open source on github.com/chengenzhao/fxcity .

Components, Libraries, Tools

Pedro Duque Vieira released a new library, a JavaFX theme called Transit Theme : “Modern look and feel, Zero tight coupling, Looks integrated on Windows, Also works well on other OSes, Light and Dark versions,…”
- The announcement of this new Transit Theme got published on Foojay.io .
- Pedro is also working on a dark mode : “JavaFX Windows are always shown in Light mode (window frames with light color). This new API I’ve created will allow the developer to set dark mode on a native window. New API will also allow other changes to a window.”
- And he added a new API to FXComponents : “To allow you to change the native Window frame color, native Window text color, and border. (Standard JavaFX API will always show a native Window frame with the same light color with no possibility to change it.)”
- The release of the new FXComponents library was also published on Foojay .
Dirk Lemmermann released version 3.0.0 of PDFViewFX : “This release is based on Apache PDFBox 3, which contains an impressive list of fixes and enhancements.”
- Dirk has a friendly reminder : “When creating custom controls for your JavaFX project, please make sure you have a way to properly test them standalone (e.g. via FXSampler ).”
- He is also pimping the CalendarView control in GemsFX and adding all kinds of options: “E.g. different layout for the header and also quick picking months and years). Come and check it out, let me know what you think or I missed.”
JavaSuns came upon this great small pure Java library, SimplePNG , for storing JavaFX images to PNG files. Great compression ratios and file sizes achieved with the use of PNGJavaFXUtils class.
A new week, a new library by Pedro Duque Vieira: FXComponents . It contains a collection of new controls to be used in JavaFX applications.
WhiteWoodCity extended JavaFX, FXGL, and AtlantaFX to reduce function of binding, multiple game scenes support and navigation of them, enhanced animations, self-made theme,… Check the X thread , as he shared the code!
Johan Vos shared a link to the GitHub project of Rich Text Area : “One of the cool GluonHQ tools we are developing/maintaining”.
Carl Dea is prototyping a new JavaFX-based Dockable windowing library .
Sven Ruppert announced the release of version 4 of TestFX , simple and clean testing for JavaFX. Check GitHub for all changes .
Sean Phillips announced a new release of the special effects library LitFX : lightning, radio waves/bands, line of sight lighting and shadowing, animated window and floating panes, flame convolution.
Michael Paus has done a basic POC for Skia integration into JavaFX .

Tutorials

Mark Baird released the second in a series of blog posts showing how to use the beta release of the Java Maps SDK (with support for Arm Linux devices) with a Raspberry Pi to integrate IoT data collection into your geospatial applications.
Edward Nyirenda Jr explains how to add TextField autocompletion in JavaFX using ControlsFX : “TextField autocompletion is a convenient feature that enhances user experience by providing suggestions or predictions as users type into a text field.”
- Check his Twitter/X timeline for more tutorials .
- Highlighting one of the many other tutorials “JavaFX Clipboard” : “In the JavaFX framework, clipboard functionality is seamlessly integrated, making it easy for developers to provide a smooth and user-friendly experience.”
- All Edward’s tutorials are available on his website coderscratchpad.com .
Gluon shared four new tutorial/screencasts on YouTube:
Part 4 of the video tutorials in French by Jason Champagne : “On aborde les premiers contrôles utilisateur sur JavaFX” (First user controls in JavaFX).
Ken Kousen (“Tales from the jar side”) shared a video : “Generate images using Java. See how to write Java to drive the Dall-E image tool. Combined text blocks, JSON parsing, records, and even a JavaFX image carousel.”
Edward Nyirenda Jr is continuing his series of tutorials: Internationalization in JavaFX: Building Multilingual Apps : “Internationalization is the process of designing your application so that it can be easily adapted to different languages and regions without code changes.”
In Portuguese by Edivaldo Brito : “Como instalar o Gluon Scene Builder no Linux via Flatpak” (How to install Gluon Scene Builder on Linux via Flatpak).

Miscellaneous

Dirk Lemmermann noticed something remarkable : “A JavaScript account retweeting a JavaFX tweet? 🙂 What’s next? Flying pigs? :-)”
Frederic Thevenet wrote a long thread on Mastodon to explain why “JavaFX is a very solid piece of tech which unfortunately came to maturity at the worst possible time for a “desktop application” GUI framework.”
Looking for a specific icon? Use JFX Central as Dirk Lemmermann explains here .
Happy to see more and more references to JavaFX when people discuss app development, like here by @t3chn01200 , here by @schramMedia and here by @Aman_Raj2241 .
Oliver Kopp shared more info about the reason to use Java 21 in JabRef : “We needed to have the fix for a workaround of the 64kb limit of Java. We did not backport our fix to JDK20, but relied on a sufficient quality of JDK21 at the time of our release.” Check JDK-8240567 for more background info and a link to the merge request and code changes in OpenJDK.
WhiteWoodCity is combining JavaFX and JavaScript : “Using #Graal polyglot in a JavaFX program.”
Webswing , a specialized web server for running Java Swing and JavaFX based applications in a web browser, announced a Spanish version of their website .
From time to time, JavaFX (just like Java itself) is declared dead. Luckily, there are many fans to correct this mistake:
- JavaFX3D : “As someone who worked on JavaFX at both Sun and Oracle, I can definitively say that JavaFX is not deprecated. Period.”
- Jonathan Ellis : “Users hate Electron’s performance and memory footprint, but devs love it for write-once-run-anywhere. I know we stopped using Swing years ago for good reasons, but still: wouldn’t JavaFX be better than Electron?”
- JavaFX3D : “I keep seeing uninformed posts, so I’d like to set the record straight. Kevin Rushforth and his team at Oracle are working on JavaFX . Equally importantly, Johan Vos and his team at Gluon are the JavaFX WORA magicians.”
- Sean Phillips : “As the lead developer for several of the tools referenced in that article I can say as ground truth that JavaFX was selected as the superior tech stack due to a combination of quality, performance and cross-platform support.”
- SystemsInCode : “I would love to leverage the benefits of JavaFX, but it’s a hard sell in enterprise when we need to push a critical fix… It’s a shame we have to use sub optimal tech for boring practical reasons 🙂 Being able to FORCE latest version on people even with low rights is critical.”
Pedro Duque Vieira shared some hidden messages : “Hint: squint, move your phone/monitor further away or zoom out, to see it more clearly.”
Christopher Schnick believes JavaFX applications can always use some more Duke .

JFX Central

The JFX Central website is now reachable via both jfxcentral.com and jfx-central.com .
Many improvements are going on…
The post by Frank Delporte about the new version of JFX Central got republished on Foojay:

Dirk Lemmermann is inviting all JavaFX developers to make their work visible on JFX Central : “In the end, you will have a nice personal profile page like this. A page showing your libs, your tools, your books, your videos, your blog, your showcase apps, etc…”
More content was added and bugs fixed and improvements integrated , go check it out on jfx-central.com …

New FXComponents Library Released

Fri, 22 Sep 2023 10:15:43 +0000

A new library for Java / JavaFX has just been released. The library’s name is FXComponents and it is a Java library that contains a collection of new controls to be used in JavaFX applications.

As of the time of writing, FXComponents is being built using Java 17 and JavaFX 20.

Below is a brief description of the controls currently present in this library (more coming soon). If you want to know more, head on over to the documentation page for more detailed information about this library and how to start using it.

New User Interface for JFX Central, the Home for JavaFX – Part 2

Mon, 18 Sep 2023 05:42:34 +0000

In part 1 of this series , we looked into the new design of JFX Central , the place to be for all JavaFX info.

JFX Central is a not-for-profit team effort. Many people are involved, and any issue or pull request provided by anyone from the JavaFX community helps to improve and extend the website, application, and data. I reached out to some people involved to learn about their history in Java and JavaFX development and how they are engaged in JFX Central.

New User Interface for JFX Central, Home for JavaFX - Part 1

Mon, 18 Sep 2023 05:37:45 +0000

Just like Foojay is the starting place for all info related to Java, JFX Central is the place to be for all JavaFX info. The website is a project started by Dirk Lemmermann and has been online since 2021. The team has expanded since then, and the content has been extended, partially by the team, but also thanks to many contributors from the JavaFX community. End of August, a new user interface was published to replace the initial version.

The DiscoAPI Helps You To Find Any OpenJDK Distribution

Tue, 12 Sep 2023 03:42:44 +0000

Did you know Foojay is not only a human-readable OpenJDK knowledge base but also provides the Disco API that lets you search all OpenJDK distributions? And even if you didn’t know, you probably already are using it, as it’s integrated into SDKMAN! , JReleaser , JBang! , Gradle toolchain , Paketo buildpacks ,and more.

The Disco API (i.e., the short name for the Universal OpenJDK Discovery API) is a database and API with all the available OpenJDK versions from all distributors, like Corretto, Liberica, Oracle, Temurin, Zulu, and many others. In total, there are now 89352 different packages at the end of August 2023.

New JavaFX theme library "Transit" released

Tue, 12 Sep 2023 02:56:13 +0000

A new Java (JavaFX) theme has been released. This is a new theme called “Transit” and it builds upon the lessons learned while developing JMetro. The code is hosted on Github .

It is not meant to be JMetro 2, it will be an entirely new theme.

Strengths and Key Principles

This theme follows some of the design principles and has some of the key strengths of JMetro:

Modern look and feel;
Zero tight coupling with this library:
- No new controls. “Pluggable” theme. Functionality is added “behind the curtains” to existing JavaFX controls through the Skin API (FXSkins library);
- Setting and unsetting is seamless and easy (only 1 line of code) even on already existing apps that don’t use this theme;
Looks integrated on Windows (80%/90% of desktop users use Windows) also works well on other OSes;
Light and Dark versions;
Easily override and customize colors by overriding JavaFX CSS variables;
Only relies on JavaFX CSS, JavaFX API and Java code (no other “foreign technologies”);
Samples and theme tester app on samples sub-project ;
Lots of real world, recognized Java apps already using it (NASA’s applications, applications used in the White House, etc, etc) (JMetro and Transit) – check the documentation page for more real world examples;
Leverages lessons learned developing JMetro theme;

I like to use the term Michael Paus (@MichaelPaus ) coined when he was referring to JMetro: this is a “pluggable” JavaFX theme (like JMetro).

JavaFX Links of August 2023

Thu, 31 Aug 2023 15:42:48 +0000

I’ve taken a holiday this month, so probably missed a lot of the amazing JavaFX news, but still some things caught my attention and you can find them in this LinksOfTheMonth overview.

But the most essential and thrilling news is the release of the new version of jfx-central.com ! A complete new home for “all things JavaFX” thanks to the amazing work of a whole team of JavaFX enthousiast . Indeed, yes, it’s a website but actually a JavaFX application, so you can also run it as a desktop app. And what’s even more important… the full sources are available on GitHub .

Building High-Performance Java Microservices with EDA

Wed, 16 Aug 2023 21:34:18 +0000

Event-Driven Architecture (EDA) is a design principle focused on the creation, detection, and reaction to events.

Renowned for its resilience and low latency, EDA is a reliable choice for developing robust, high-performing microservices.

Moreover, this method can be helpful in improving productivity and making the process of cloud migration smoother.

In this article we will outline 6 key considerations and tactics for developing such services.

1) Crafting Event-Based Microservices

Within EDA, microservices interact with each other through events. An event is simply an immutable indication that something has happened. Microservices register their interest in a subset of events and perform their processing by reacting to these events when they occur. On completion of handling of an event, microservices will usually post one or more events reflecting the result of this processing, which will trigger further downstream microservices.

Pi4J Operating System for Java development on Raspberry Pi

Fri, 11 Aug 2023 10:19:50 +0000

Yes, the Raspberry Pi Operating System is awesome! But the Pi4J project made it even more awesome by adding “goodies” for Java developers! Pi4J OS is not yet another OS, but the official Raspberry Pi OS, with additional tools and preconfigurations to make it the ideal OS for any Java and JavaFX developer who wants to use a Raspberry Pi.

The project is shared on GitHub and documented on the Pi4J website . The zip-compressed archives of released versions can be downloaded from pi4j-download.com .

JavaFX Links of July 2023

Fri, 28 Jul 2023 07:50:36 +0000

Billions of Messages Per Minute Over TCP/IP

Wed, 05 Jul 2023 21:05:08 +0000

Key Takeaways

Data consistency is critical when communicating between software components on different machines to ensure information remains in tact.
Low-latency data exchange requires a different approach than common formats.
Chronicle’s open-source Wire library provides a highly efficient means of marshalling and unmarshalling data for transmission to and from Chronicle Queue.
Recent additions to the library extend its use with TCP/IP communications channels, offering extremely high throughput.
Using Wire across TCP/IP opens up the possibility of Cloud Native deployment of Chronicle-based applications.

Introduction

One of the most important issues when building distributed applications is that of data representation. We must ensure that data sent by a component to a “remote” component (i.e. one that is part of a different process) is received correctly, with the same values. This may seem straightforward but remember that the communicating components may have been written in completely different languages.

JavaFX Links of June 2023

Fri, 30 Jun 2023 09:18:30 +0000

Again a lot has been shared this month in the jfx-central.com #LinksOfTheWeek! And that website itself is “under heavy construction” as version 2 is getting a completely new design and several improvements. Your help is wanted! See the last section of this summary…

Core

Rampdown Phase 1 (RDP1) for JavaFX 21 starts on July 13, 2023 at 16:00 UTC (09:00 Pacific time) , about four weeks from now.
JavaFX 21 Early-Access Builds Build 21 is available from jdk.java.net/javafx21 , addressing these issues . JavaFX 21-ea is designed to work with JDK 21-ea, but it is known to work with JDK 17 and later versions.
Johan Vos is planning to spend more time on Java on Mobile (OpenJDK Mobile) in the near future: “There is 0 support from big tech because they fall in 2 categories: 1/ they have no revenue on mobile, 2/ they have competing OS tech that drives devs/users to their revenue-driven cloud services. But since I’m not big tech, I can just do it.”
Gluon asks all JavaFX developers to give JavaFX 21-ea+21 a try .
- And is working on making their JavaFX software (libraries, tools, components) more consistent and developer-friendly : “Over the past years, we learned a lot, and we’re putting that experience now in our code.”
Dirk Lemmermann is looking for help with a Webkit issue in JavaFX 18.0.1 .
Abdelrahman Bayoumi explores a solution to resolve the challenges when it comes to rendering Arabic, being a right-to-left script .

Applications

Sean Phillips is almost ready to make the sources of Trinity available …
- He is using Trinity to distinguish between human and chatGPT altered text .
- After teasing us for a few weeks, it finally happened! Sean Phillips announced that Trinity, an Explainable AI Analysis and Visualization tool written in Java and JavaFX, is now officially public and open source. His message: “Have fun you fine young cannibals.”
- Video demo of Trinity to project and distinguish between human and chatGPT altered text blurbs .
- With many thanks to JavaFX 3D , Jasper Potts , Alexander Kouznetsov , Chien Yang , Kevin Rushforth , Richard Bair, and many others for all their hard work on JavaFX and 3D and more!
- Sean Phillips shared a screenshot : projecting decision manifolds from Pilot Assist AI Models for dog fighting pilots.
- Rendering a rainbow highway .
- Johan Vos is still impressed by the Devnexs keynote given by Sean : “This is a very cool demonstration about Trinity, an open-source tool developed/used at John Hopkins University. It shows how Java developers can create cool, amazing and extremely useful stuff with great visualization using JavaFX.”
Christopher Schnick improved the speed of Pdx-Unlimiter with cached dynamically generated images.

Christopher Schnick gave the welcome page of v1.2 of XPipe some personality .
Dirk Lemmermann really likes the latest version of the sample app for AtlantaFX : “Very nicely polished theme and controls. Packaged with Conveyor from HydraulicDev.”
Maciek Gorywoda shared v1.0.0 FxCalculator : “It’s, well, a calculator for your Android phone.” Read the whole thread to learn more, e.g. that it’s written in Scala 3.3, JavaFX, Gluon, and built with GraalVM Native Image.
Jamie Macaulay is working on SUDUnpacker to handle SoundTraps sud files.

Games

Johan Vos stumbled into this addictive web game, written in JavaFX by Gerrit Grunwald using WebFX: tetris.webfx.dev : “It’s great to see how developers are using JavaFX to make cool stuff.”
OrangoMango made Snake v1.0 available on itch . Thanks to WebFX, there is now a web version that is playable in the browser (fullscreen is recommended).
- He extended his chess game with drag and drop, and improved the image resolution.
- He also shared a video showing collision detection with convex shapes . It resulted in a nice chat with Sean Phillips and Carl Dea .
- He added a teleport stone, a propeller, and rotating platforms to FoodDice . New levels with those new items are coming in the next update. Also implemented the new collision system that he wrote before for these new rotating items.
- And he has been experimenting with a physics engine made from scratch . Right now, there are just some basic physics laws and chains.
Another JavaFX game has been ported to the Web with WebFX Food Dice! . It’s a plain JavaFX game written for the GMTK Game jam 2022 and was coded in 48h from scratch with no 3rd party lib. Congrats to the 16-year-old author OrangoMango** . Play online on fooddice.webfx.dev .

Miscellaneous

Donald Raab is hoping to get back to experimenting with JavaFX again this summer and to submit conference talks…
Sten Nordström is looking for JavaFX tutorials : “Asker has experience with other platforms and some Java knowledge. Online, or possibly in person in Scandinavia/Northern Europe.” Who can help him? First starting point should of course be: jfx-central.com/tutorials 😉
A help request on Reddit to build a JavaFX project in VsCode .

JFX-Central

Service call to all the people who have “something” on JFX-Central (library, book, tutorial,…). We are reviewing all info on the website in preparation of the new JFX-Central version. But we need your help, please contact us or make a pull request in jfxcentral-data to make sure all the info is still correct and up-to-date. Thanks!
More previews of version 2 of jfx-central.com:
- Dirk Lemmermann is drooling with the layout .
- And more drooling …
- Social login capabilities were added .
- And he is having almost too much fun 🙂 Added banners to the tips and tricks pages .
- Finding out what’s coming to the next JavaFX release will be super easy by visiting the new OpenJFX page on JFX-Central .
- Finding that one library you recently heard about will be easy via JFX-Central… and who wrote it, and videos showing it, and the repo coordinates, and and and .
- Lee Wyatt, one of the main contributors to the new JFX-Central version added a “Credits” page, one of the many pages he created and/or improved.
Dirk Lemmermann wants your opinion about a new logo for jfx-central (and JavaFX itself?)
- First idea with a lot of remarks and adjusted proposals by others .
- The next proposal .
- After many iterations, Dirk found the perfect new logo : “Work on the logo for the JFX-Central website is finished. In the end large, small, color, black, white, etc…. versions were needed to make it look code in all places.”
Testing the layout of the new version with “responsive design” mode is in Safari .
And the new desktop version will come with its own custom stage when running on desktop . Other improvements for the app version of the new JFX-Central:
- A couple of screens were added for a nice bootstrap sequence . When running the app for the first time it will clone its data repo (takes a while). Any launch after that will perform an update on it (fast).
- It will also come with a tray icon for quick access to anything JavaFX
- It is now an even better citizen when running on Mac . Can you spot the difference aka the “dots”?
We have been very busy working on the new JFX-Central version… Maybe you want to help out? The repository is now public ! Feel free to make contributions. Testing, and reporting bugs. All are very welcome.

Building Custom Solutions vs. Buy-and-Build Software

The Challenges of Building a FIX Engine

The first day I was introduced to Financial Information eXchange (FIX) was when I worked at an investment bank in London as a developer.

I was told to write a feed handler to retrieve market data.

Bear in mind that at this time, I knew nothing about FIX, apart from Googling it for about 10 mins on the internet.

With a touch of overconfidence and slight arrogance, I set to work coding a direct socket connection to the remote FIX endpoint, “how hard could it be?”

Foojay Podcast #25: Game Development with Java, JavaFX, FXGL

Mon, 19 Jun 2023 08:56:11 +0000

Java and JavaFX are probably not the first options you consider if you want to create a game application.

But the FXGL library allows you to do precisely that! Create games that run on all platforms with the same codebase as we are used to with Java.

And even without an extra library, the JavaFX Components and Canvas provide many animation and gaming possibilities.

Let’s learn from experts why Java should be on your game-development-language-list!

Java is Very Fast, If You Don’t Create Many Objects

Thu, 01 Jun 2023 04:45:56 +0000

This article looks at a benchmark passing events over TCP/IP at 4 billion events per minute using the net.openhft.chronicle.wire.channel package in Chronicle Wire and why we aim to avoid object allocations.

One of the key optimisations is creating almost no garbage. Allocation is supposed to be a very cheap operation and garbage collection of very short lived objects is also very cheap.

Does not allocating really make such a difference? What difference does one small object per event (44 bytes) make to the performance in a throughput test where GC pauses are amortised?

JavaFX Links of May 2023

Wed, 31 May 2023 06:48:43 +0000

Again a busy month in JavaFX-world! Here is a nice list with links for your reading and clicking pleasure!

This is the summary of the #LinksOfTheWeek as published on jfx-central.com in May 2023.

JavaFX Core

JavaFX 21-ea+17 is available for download from GluonHQ or from Maven central .
Johan Vos believes it’s time to deprecate Java Swing : “It doesn’t make sense to maintain Swing and move JavaFX forward. Deprecation doesn’t mean it needs to be removed immediately. But let’s deprecate it. We need to move forward, and we need the resources for this.”

SceneBuilder

Raumzeitfalle is wondering if you want to conveniently install Scene Builder 20 for JavaFX ? You can now do this thanks to the use of JDeploy.
- This new version now offers a direct menu shortcut to jfx-central.com !
- This release uses JDK 20.0.1 and JavaFX 20.0.1 .
Shared by Johan Vos : “Now that Scene Builder 20 is released, it is a good moment to work on functionality/bug fixes that can make it in 21. For most projects I work on, I prefer doing major changes shortly after a release, rather than shortly before a release.”

JavaFX Applications

Shared by MarsX.dev: Lunatics , a JavaFX-based email testing tool with a dummy SMTP server that lets you test email sending applications, monitor transactions, and simulate various network conditions.
Clemens Lanthaler announced LibrawFX 1.8.4 with speed updates and raw settings added, using JDK 20 and JavaFX 20.
Homebookner shared SANEScanFX, a scanner application , not finished yet but already usable.
Pedro Duque Vieira proudly shared that Modellus received the recommended award again this year from Mac Informer (3rd consecutive year)! It’s a freely available app used worldwide that enables students & teachers (high school and university) to use mathematics to create or explore models interactively.
Christopher Schnick is working on context menu actions for XPipe . What else would you like to see added?
- And he shared a video with more AtlantaFX themes plus smooth theme transitions .
Alessio Vinerbi seems to be working on MoonsonFX , an alternative AfterEffects application. This makes me very curious as he already showed other impressive UI-work.
Juanan seems to be working on a Mastodon client , see also his other Toots on Mastodon.
binjr (FOSS timeseries browser) 3.12 is available , with a new indexing mode for log files that makes it easy to search for arbitrary strings of character without the need for wildcards while maintaining the same level of performance, even on very large files.
Sean Phillips shared several images and videos of Trinity, an AI / ML analysis tool.
- By colorizing Binary Classification feature space from a deep learning model using JavaFX 3D we see decision manifolds have subgroupings.
- And an extra one with Trinity’s UMAP projection cluster data maintaining references back to their hyper-dimensional vectors and imagery . This demonstrates anchoring 2D nodes to Shape3D nodes as the PerspectiveCamera is rotated.
- Too complex to understand? I agree, but his work is just amazing and really mind-blowing 😉
- If you want to know more about it, this is a link to an interview of December: “Visualizing Brain Computer Interface Data Using JavaFX”
- And in those tweets he announced Trinity will be available soon on Github!
- UMAP projector to visualize COVID infected tissue samples, clustered by genetic sequence classification . Clear distinction between brain and body tissue using the Yule metric.
- Process, cluster and render COVID tissue samples by genetic sequence code classification .
- Similar, using the Yule distance metric, with 2500 samples each with over 18k dimensions !
- Don’t tell anyone, but Sean is actually a time traveler, who worked (will work?!) on the StarTrek user interfaces…

JavaFX Games

Pac-Man and Ms. Pac-Man by Armin Reichert ported to the web with WebFX .
Rubik’s cube v3.0 by OrangoMango is available on itch.io for Windows, Android, Linux and Mac.
- He also shared his Chess game : sources and executables for Windows, Linux, macOS and Android. Features: play agains stockfish or LAN multiplayer, export game as FEN and PGN, arrows, premoves, time control, and much more…
- And a link to the sources of his 3D engine and the Minecraft-clone .
Almas Baim shared a video of a game where the player can now use the shockwave ability once the meter is full. It allows the player to quickly clear out a safe path in front of them.
- And he had a fruitful discussion with game dev students on how to improve the UI . In the video, you can check out the new health and weapon indicators around the player, without the need to look elsewhere to get this info.

JavaFX Components

Matt Coley made a minimal/flexible TreeMap chart .
Christopher Schnick is feeling magic with dynamic OS theme detection ! Done with jSystemThemeDetector.
Sean Phillips got a lot of interest on the animated circular progress indicator he made for Trinity and uploaded a version of it along with a tester app so folks could play with it.

JavaFX on Foojay.io, the website for Friends of OpenJDK

“If the user has installed programs to connect to remote systems, why not try to use them from Java instead of via libraries?” And then, on top of that, a tool for people who work with remote shell connections? Christopher Schnick presenting X-Pipe.
Interview by Frank Delporte with Paul Kocian aka @Orango_Mango , who shared his progress on Twitter in creating a 3D engine with JavaFX, from a Rubik’s cube in January ‘23, over a basic tumbling car in February, to a full Minecraft-like world in April! His age? 16!

Podcast

Adam Bien and Shai Almog discuss JavaFX, Codename One, Swing, Flutter, and a Bit Android .

- Sneak preview of the new website taking advantage of Safari’s unified toolbar , aka “theme color” meta tag.
Dirk Lemmermann shared a lot of previews of the upcoming new version of jfx-central.com.
- The “skeleton” for the detail pages . It will be used to list information on people, books, libraries, tools, blogs, etc… Every page will be responsive and auto-adjust to large (desktop), medium (tablet) and small devices (phone).
- The new showcases section .
- Videos will no longer be shown in a separate overlay, but “inline” .
- Ikonli will also have a nice new home .
- The shiny new home for the “links of the week” section . Also coming soon… the RSS button.
- Having a professional designer do your app’s design is always worth the money . Not only do you save time, but it will also look much better.

"Transitioning to Java": My First Book!

Wed, 24 May 2023 08:01:58 +0000

When I retired from the classroom in 2021, I had no intention of sitting on a rocking chair on my front porch.

I looked for speaking opportunities, became a member of the JCP EC, and continued thinking about ways to enhance Java teaching.

I also wanted to write a book. I approached a number of publishers with my idea for a beginner’s book. I even wrote a sample chapter and publsihed it on my blog, https://www.omnijava.com/2021/10/20/java-for-beginners-my-unsuccessful-book-proposal/ .

Monitoring Event Loops for Blockages

Mon, 15 May 2023 16:42:18 +0000

Chronicle’s open source Chronicle Threads library has a little known feature which is one of the first tools I get from my bag if a client reports that they are seeing latency outliers.

The usual way that a developer will measure their system for latency hotspots is to use a profiler, and modern profilers are amazing; there are numerous commercially available, but I generally find myself using Java Flight Recorder, async-profiler, or honest-profiler. These three are engineered to avoid the safepoint bias , and thus give very accurate results.

Unconventional Remote Process Control in Java

Mon, 08 May 2023 14:03:08 +0000

Have you ever wanted to control a remote process from a Java application? Essentially something like a ProcessBuilder for remote systems that allows you to run and configure a process on almost any system and also supports all regular features that you would expect from it.

Now obviously, this isn’t a revolutionary idea. You can easily take an SSH library like the newer jsch fork and use the exec or shell channel to control remote processes or remote shells by just copying and pasting some tutorial code. So what is this about then?

Interview with Paul Kocian aka Orango_Mango

Mon, 08 May 2023 07:49:40 +0000

Some time ago on Twitter, I discovered @Orango_Mango , who shared his progress in creating a 3D engine with JavaFX. The shared videos started with a Rubik’s cube in January ‘23 , over a basic tumbling car in February , to a full Minecraft-like world in April . Who is this @OrangoMango? And why did he take up the challenge to create a 3D engine with Java and JavaFX? Let’s find out…

Approaches to Durability in Low Latency Messaging Queues

Wed, 26 Apr 2023 13:17:59 +0000

A significant feature of Chronicle Queue Enterprise is support for TCP replication across multiple servers to ensure high availability of application infrastructure.

I have generally held the view that replicating data to a secondary system is faster than sync-ing to disk, assuming the round trip network delay wasn’t high due to quality networks and co-located redundant servers.

This is the first time I have benchmarked it with a realistic example.

How Not To Skip A Message Even If Your Data Centre Fails

Fri, 07 Apr 2023 15:21:31 +0000

A high level of availability of IT services is crucial to prevent disruptions of service that can lead to financial losses, business opportunity losses, data loss, and reputational damage.

A business’s downtime cost can vary depending on its size, nature and the length of the downtime.

Studies by Network Computing, the Meta Group, and Contingency Planning Research have identified financial services and telecommunications as industries with the highest revenue loss during downtime, demonstrating the importance of FIX engine high availability.

JavaFX Links of March 2023

Fri, 31 Mar 2023 12:56:00 +0000

Already the end of March, so time to look back at the JavaFX Links Of The Week that were published on https://www.jfx-central.com/ .

JavaFX Core

Johan Vos is working on backports for JavaFX 17.0.7 to guarantee quality and long-term support.
- And he announced JavaFX 20 could be released in the week of March 20th . As planned.
Together with the release of OpenJDK 20 , we also got the release of OpenJFX 20. Both right on schedule, as always!
- Announcement by Gluon .
- Downloads are also provided via OpenJDK on jdk.java.net .
- Important message in the release notes : “JavaFX 20 is compiled with –release 17 and thus requires JDK 17 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read.”
- Most important highlight for Johan Vos : “apps created many years ago still run on the latest JavaFX with latest OS. That is far from trivial, require lots of work, and not very common in client frameworks.”
- And another quote from Johan : “I remember people and companies telling me 5 years ago they love Java and JavaFX, but they were pretty sure JavaFX would not be around in 2 years from them. So they used other client technologies… which don’t exist anymore today… while JavaFX… keeps moving forward. With less hype, and less marketing power than other client frameworks, but with dedication and focus on quality, stability and community. And with tons of stuff todo, I 100% realize that.”
You can already start experimenting with JavaFX 21 Early-Access Builds!
- Get it from Gluon .
- Or OpenJDK .
A request by Raumzeitfalle : “If you like Java and JavaFX, give Scene Builder Leadinge Edge a try. Its latest version runs with Java 20 using JavaFX 20 and it combines many of the pending PRs so that one can test the functionality. Feel free to share your feedback on Github.”

JavaFX and Game Development

17.0.13 of JArkanoid by Gerrit Grunwald adds the ability to shoot enemies.
- He describes in a Foojay post how to turn an existing application to an iPhone app .
- And he started with a new game, as you can see in this first screenshot of loderunner .
- He shared the first version of a Tetris clone .
- This is a screenshot .
- You can play it online, thanks to WebFX .
Markus Eisele shared a link to the GitHub project of pacman-javafx : a JavaFX UI (2D+3D) for Pac-Man / Ms. Pac-Man, a project by Armin Reichert.
Another Minecraft-like world, in the self-made 3D engine of OrangoMango .
- It got extended with more Minecraft-like functions : block breaking/placing, terrain generation, chunk system, and overall performance improvements.
- He added some new block types and fixed some issues with block breaking/placing in his Minecraft-like world , and now has a small home made out of wood and coal blocks.
- It also has Minecraft-like trees .
- Sean Phillips - being a JavaFX 3D expert - finds his work awesome .
WhiteWoodCity shared a video with the combination of 2D and 3D game sub scenes.
- Another video of a rougelike game prototype .
- And shared how he created a pseudo 3D effect like Street of Rage, Dragon’s Crown with two GameSubScene and two entities of each GameWorld, and binding their properties with very clean and neat code.
- His game got bumped to Graal and Java 20 . Yes, indeed, already before the official release of Java 20!
- And shared how he created a dynamic shadow effect of a jump action with a Shape and Binding in less than 40 lines of code.
Almas Baim has been very active on this month…
- He discovered another FXGL game : “The Last Cowboy Game - UTFPR”.
- And he shared a screenshot showing FXGL is available in IntelliJIDEA when creating a new JavaFX project.
- Announcing version 17.3 of FXGL : improve A* performance, isometric support for .tmx, 3D updates (lookAt, direction, rotation, .obj models), propertyMap convenience API.
- Pathfinding solution added to FXGL that outperforms the existing one by up to 80% , by replacing ArrayList with HashSet in critical code.
- Another video with the FXGL engine pathfinding in action . This demo shows large red areas that are not passable, while dynamic entities are ignored and can be passed through.
- Video showing physics sandboxes are never not fun ! You can now pick up any entity as seen in this sample.
- Video of text animations with particles .
- Video with particles, one as “lead” , and other particles following with min and max distance, ensuring all particles are connected while the lead moves.
- Isometric tile support in FXGL has had significant interest over the years . The maths looks straightforward but the architecture, as per usual, will need some careful pondering.
- Screenshot of initial progress towards having first-class support for isometric levels in FXGL.
- Video showing the new sliders in FXGL .
- He is throwing grenades… .

JavaFX in Science

Fabrice Jossinet shared an impressive preview video of a new tool to visualize the folding pathways of an RNA during its transcription. Pathways are computed with a Rust algorithm. Visualization and GUI are made with Kotlin, JavaFX and his rnartistcore library.
RNArtist shared again an impressive video showing RNA visualization with JavaFX.
- “In RNAStudio, you can animate the transcription process along one of the computed folding pathways. When a new helix pops, it is first highlighted then added to the 2D. You can stop/restart the animation, go backwards/forwards.”

Miscellanous

jdeploy by Steve Hannah now produces signed apps for Windows installers . This should make Windows Defender more pleasant to be around.
Dirk Lemmermann has also been very active…
- TableView replacement based on GridPane. No virtualisation . Very useful for small datasets. Will be added to GemsFX very soon.

- The TimePicker in GemsFX has been improved by @cpreisler . It can now also display and edit seconds and milliseconds.
- He’s looking back at something he implemented almost 20 years ago with Java 5 and Swing , and it still works perfectly nowadays with Java 19 … just a whole lot faster!
- He showed a custom tooltip implementation for charts . The tooltips show the values of all y-values for the same x-value whenever the mouse cursor hovers over one of the data points.
- In a comment tweet, he shows code to illustrate that each data point in a JavaFX chart is also a node that allows us to integrate such a feature.
- Read the comments to learn pro/contra of this approach and alternatives for large datasets.
- He added a YearMonthPicker control to GemsFX . It’s included in version 1.67.0.
- It was the result of a deep-dive into how to customize a ComboBox .

Steve Hannah shared a GitHub action to generate native installers for Java desktop apps.
SmartFinder by Serendipity version 1.7.3 now runs with JavaFX 20 ! It’s a Desktop Search Tool APP fully developed with Java and JavaFX technology.
Dirk Lemmermann again shared a lot of JavaFX library and other info:
- “If any of you work on planning and scheduling applications I can highly recommend #FlexGanttFX for visualizing plans / schedules . Yes, it is a commercial library.”
- “If your JavaFX application requires an on-screen keyboard, you might wanna check out KeyboardFX .”
- A screenshot of the new market data portal he is creating, running in a browser .
- The new calendar view in GemsFX now also supports “date range” selection (and single date, multiple dates selection).
- Thanks to Florian Kirmaier, GemsFX has been extended with a great utility class for synchronous scrolling of two VirtualFlow instances .
- And he’s worried about his job as “ChatGPT “generates” a JavaFX app based on requirements” . That’s probably thanks to the stability of the API over the last years!

JavaFX Links of February 2023

Tue, 28 Feb 2023 11:24:43 +0000

February is a short month, but this list seems to be longer than ever…

A lot of game and 3D development, releases, interesting ongoing development, and so much more to read. Enjoy reading and clicking!

This is a summary of the Links Of The Week as published on jfx-central.com during February.

JavaFX/OpenJFX Core

Kevin Rushforth of Oracle announced on the mailinglist “As a reminder, JavaFX 20 is now in Rampdown Phase Two (RDP2). Now that we are in RDP2, the goal is to stabilize what is there”. So we will soon get a new version of JavaFX being released!
Chad Preisler wants to thank all JavaFX maintainers : “The people that maintain and enhance #JavaFX are great. They fixed an issue with Mac back in December, and today when a dev got a M1 all we needed to do was update the JavaFX dependencies. Everything runs great now.”
Gluon announced public access to its JavaFX 17 builds , including 17.0.6 and subsequent versions.
- With an important note regarding version compatibility: “As the development of JavaFX 20 picks up momentum, it’s important to note a key change – JavaFX 20 will require Java 17 or later.”
- Johan Vos of Gluon also shared : “Gluon leverages GraalVM in Gluon Substrate, allowing JavaFX apps to be converted into native client apps for desktop, mobile and embedded.”
- They announced improved sound support for iOS in Gluon Attach.
- And thank Bruno Salmon for a great contribution by adding the iOSAudioService.
- See the code changes in the pull request , optimised for games that may play sounds simultaneously frequently, without degrading performances.
Dave Barrett is a big fan of JavaFX + Kotlin : “it’s a match made in heaven. Kotlin gives you the tools to streamline your layout code in ways you never could in Java.”
Chad Preisler shared a 5 minute about property binding : “JavaFX makes getting data from your form controls into your model very easy.”.
Gerrit Grunwald warns about the JavaFX Canvas being really nice and fast, but “be beware of effects… Using one simple dropshadow in a GraphicsContext can really bring down performance… Just as a reminder.”

Scene Builder

Raumzeitfalle shared an update for Scene Builder Leading Edge : preview of unofficial and features-in-progress. February 2023 brings us support to create controllers in Scala and JRuby and a Chinese translation.

UI Development

WhiteWoodCity shared a lot of JavaFX news:
- He found this impressive video of VFX , a JavaFX UI framework .
- The sources of VFX are available on GitHub .
- A video of a self-made new JavaFX UI by WhiteWoodCity .
- How to use of VFX components to decorate a JavaFX application with a link to video and sources.
- A video of a nice JavaFX UI .
In the previous edition of this list, a link was included to Matt Coley sharing his wish-list to extend RichText. There is a GitHub issue by Andy Goryachev of Oracle asking for “Any missing APIs in JavaFX which are needed for RichTextFX” to gather feedback.
Sean Phillips spotted a JavaFX user interface on a transparent Science- Fiction-like screen.

JavaFX Libraries

Frank Delporte shared it is still a long way to go, but Lottie4J can now read both fixed and animated beziers . It includes a screenshot of the very first result of a loaded animation with colors, strokes, fills… being the next step.
- And shared a link to an article why it could become important to have a JavaFX implementation of LottieFiles: “4.7 Million Motion Graphics Designers and Developers Turn to Lottie for Efficient Animation Workflow.”
- Lottie4J is making small progress in bringing LottieFiles animations to JavaFX with a first correctly colored stroke width and color.
Dirk Lemmermann created a new project on GitHub called LayoutFX and would like to use it to collect interesting layout solutions for JavaFX. If you have any custom panes with fancy approaches to laying out scene graph nodes and would like to contribute, then please feel free to add it.
- And he’s adding a custom control to GemsFX that allows to horizontally position and scroll multiple cells based on an items list . The control fades out to the left and right.

Miscellaneous

Not directly JavaFX related, but nice to know… Heinz Kabutz shared graphs showing that a lot of the work in recent Java versions was to stabilize and improve the platform, rather than just adding hundreds of new classes. The number of lines of code might even decrease in the future.
The research team of Almas Baim completed basic initialization and setup steps for UI and robot interaction. The hype is real at the Robotics AI Lab.

Porting an Existing JavaFX App to iOS

Fri, 24 Feb 2023 11:42:11 +0000

Sometimes there are JavaFX apps that I would also like to use on my iPhone but I wrote them for the desktop and it’s always the question how to do that?

These days the simple answer is use Gluon Mobile . But the real question remains… how to do it?

To give you an idea, I will take my little game called JArkanoid (a clone of the game Arkanoid from Taito from 1986) as an example.

Miscellaneous

Thanhpv is impressed by the performance of JavaFX on a 10y old computer. The screen recorder couldn’t catch up…
According to ChatGPT there are several advantages to using JavaFX over Swing or SWT .
You want more information about the OpenJFX project than you can find here on jfx-central.com? Visit mkpaz/aboutfx on GitHub !
According to the “2022 Q4” chart on “Java InfoQ Trends Report - December 2022” , OpenJFX is now considered a software development topic for the Innovators! So a call-out to all innovative people reading this… JavaFX is the way to go! 🙂
MichaelPaus shared this valuable link: “A very informative, but little known, source of information is the JavaFX tag info on stackoverflow: stackoverflow.com/tags/javafx/info . The FAQs cover all the things that are frequently asked on SO and actually should be consulted first before posting a question.”
- He also shared that he crossed the 10K reputation limit on Stackoverflow (which gives you access to the moderator tools), by answering mostly JavaFX related questions!
Matthew Wheeler (via YouTube) uses JavaFX 3D to randomly generate galaxies.
Dirk Lemmermann shared a teaser of the new layout for jfx-central.com.
Shared by JavaFX3D : “Go from Figma to a fully Responsive JavaFX Application with support for navigation, responsive sizes, images and more.”
WhiteWoodCity shared a video of a self-made TableView.
- Dirk Lemmermann replied this is actually an important tweet . as many JavaFX developers think they “have to” use the TableView, and then complain about its limitations. Using GridPane you can create your own custom table view, as most HTML devs do for tables.
- And another video showing a HDFS management system created with JavaFX .
Matt Coley discovered that JavaFX CSS allows you to effectively create borders just with the background color/insets property. This fixes the effect of changes in the component when you add a border, and padding changes are needed.

Frank Delporte announced he started working on a new Java library to load and save #LottieFiles and #dotLottie, plus a #JavaFX player . The very early steps are taken with a website, Mastodon account, different Lottie JSON files can already be loaded and saved back to the same JSON, and a very first visual output shows there is some valid data being handled. Maybe you have ideas how to move on with visualizing and animating in JavaFX and want to contribute?
- He also made his Udemy course to learn how to use JavaFX on the Raspberry Pi available for FREE .
During the JChampions Conference, Gail Anderson and Paul Anderson presented “Say the Words: Modern Java with JavaFX for Rich Client UIs” .

Building JavaFX with Gradle

Thu, 05 Jan 2023 11:32:24 +0000

Usually Maven is my build tool of choice and for Java front-ends I sometimes still build a front-end application using ANT, Swing with Oracle’s JDK 8u202 and JDK 8’s Java Packager, but don’t tell anyone….

Over time, as I wanted to move forward with some more lightweight front-ends, I started building JavaFX applications.

Of course, I don’t want to lock customers into JDK maintenance contracts; for backend software and servers, where the customer usually has their own runtime architecture, that’s easy, but for GUIs, I generally don’t want to ship a full JDK anymore, I want to use modular Java, ship a JDK of my choice, and provide a proper build system for it all. So that’s it, I use the following components and software:

Foojay Podcast #9: State of JavaFX, Libraries, and Projects

Mon, 19 Dec 2022 08:09:31 +0000

JavaFX was introduced by Sun Microsystems in May 2007 and provides a platform for desktop, mobile, and embedded applications built on Java.

Libraries and software are available for the complete lifecycle of an application to run from a single codebase on Windows, macOS, Linux, Android, and iOS. JavaFX was originally part of the JDK, the Java Development Kit, and became a standalone technology in 2018.

The development is a joint effort between Oracle, Gluon (a small Belgian-based company), and the community.

Visualizing Brain Computer Interface Data using JavaFX

Fri, 09 Dec 2022 09:42:20 +0000

Recently Sean Phillips shared some fascinating screenshots on Twitter and videos on YouTube of Trinity, a JavaFX application he is working on.

He is a software engineer at the Johns Hopkins University Applied Physics Laboratory (JHUAPL ), specializing in data visualization for multiple projects. JHUAPL works on various projects, ranging from medical work, building drones, cyber defense, and brain-computer interfaces to cislunar defense systems.

The project that caught my eye is a visual exploration tool to test and evaluate machine learning decision-making and decoding systems.

JavaFX Links of November

Thu, 01 Dec 2022 15:04:22 +0000

Time flies when having fun…

So here we are again, another month has passed and this is a summary of the Links Of The Week that were published on jfx-central.com during November.

JavaFX Core

We already shared here that Oracle will also be distributing JavaFX builds, and you can see the announcement they did at JavaOne here .
- Takaaki Sugiyama shared a lot of screenshot pictures of the JavaOne presentation “JavaFX 19 and Beyond” , and the full presentation by Kevin Rushforth is available as a PDF here .
- Inside Java published a podcast with Kevin Rushforth, OpenJFX Project Co-Lead, working at Oracle.
Early-access builds of JavaFX 20 are available from
- Gluon
- Oracle

SceneBuilder

A feature in development for SceneBuilder: drop one or more FXML files into the welcome page to open them, as you can see in this video shared by Raumzeitfalle .

Games

JavaFX Chess by John Sirach is not a new project, but Jakob Jenkov shared a tweet about it , and it’s always nice to see a video of this amazing project .
JavaFX3D shared some nice links:
- Monopoly game implemented in JavaFX as a student project by Titof Abdellatif Anflous .

Learning

Dave Barret has a lot of very nice tutorials on his site! For instance “An Introduction to Model-View-Controller-Interactor” .
Neba Desmond on Twitter: “Day 24 of #100Daysofcode. Today was about making menus in #JavaFX” .
Donald Raab shared a blog about building his very first JavaFX application with IntelliJ IDEA .

New on jfx-central.com

Real-world app: “HERO” by Pedro Duque Vieira , a CAD application for calculating the energy efficiency of dwellings.

Other…

JPro announced a new version 2022.1.6 with a modernized FileUpload API, support for multi-file upload, and browser native scrolling.
- This means jfx-central.com now also uses this new scrolling implementation.
Dirk Lemmermann expressed his admiration for CSSFX that saves him a lot of time while developing by providing CSS reloading functionality in your running application.
Two months ago, Robert Ladstätter announced the 1000th download of LogoRRR, another JavaFX GUI application! This week he passed the 2000 downloads ! Congratz for a great app!!
- BTW, Robert is looking for help: “How can you extract time instant information from log files” .
WebFX announced that Modality chose WebFX as its UI toolkit, being the first real-world WebFX application in development, and is driving forward the WebFX enterprise features. See video in the tweet .
A lot of the Links Of The Week are found on Twitter. But for a few weeks that medium lost a lot of its fun (in my opinion) since the take-over by Musk. So I’m slowly moving to Mastodon as my new “source of truth and inspiration”. It is a-kind-of-Twitter-alternative, free of advertisements and based on an opensource project. And then it’s fun to discover an (old) Mastodon client application in Kotlin and TornadoFX by wakingrufus . You can find it on GitHub . It probably needs some updates, but it could be the start of something fun. Take a look!
- If you want to create a Mastodon account or want to move to a server dedicated to the OpenJDK, Java, JavaFX, JVM,… community, you can join foojay.social that was created this week. For more info, check the posts on Foojay.io, the website for the Friends Of OpenJDK .
jWin by Zinelabidine Teyar: a Java tool that compiles and packs your app as a Windows installer.
Teaser: end of November a Foojay Podcast was recorded about JavaFX with Johan Vos , Dirk Lemmermann , Gail Anderson , Pedro Duque Vieira , and Sean Phillips . Still some editing to be done and will be published around the 20th of December as a Christmas present 😉

Gossips: An Event-Bus in a Chatty Neighbourhood

Thu, 24 Nov 2022 08:35:32 +0000

In this article, we’ll tackle a common issue: simple communication between system components. With a slightly controversial, themed, domain-driven design.

Though this post has nothing to do with Android, we need a context where an Event-Bus is needed. And boy oh boy is it needed in Android! And we’ll use this as an excuse to write an Event-Bus.

I chose an analogy for the entire thing: Gossips;\

It fits with the nature of the library, and the way it’ll be used. A global pub-sub component to enable cross-component communication.

JavaFX Links Of October

Mon, 31 Oct 2022 16:15:24 +0000

When I (re)started the JavaFX Links Of The Week on jfx-central.com in September, I was wondering if there would be enough material to share every week.

But that was a stupid mistake as you can see below in the summary of what happened in October… 🙂

JavaFX 19 and 20

JavaFX 19 just got released a few weeks ago, but Johan Vos is already looking forward to the next one: a really-worth-mentioning improvement that will be in JavaFX 20 is the update to MarlinFX 0.9.4.6 by Laurent Bourgès . Thank you very much Laurent for your contributions. They are an important part to the success of JavaFX. See JDK-8287604 .
- Laurent is even sharing his TODO list on GitHub in case you are curious about what he is working on…
Want to test JavaFX 20 Early Access? It’s already available on the Gluon website !
Up till now, each of the newer JavaFX versions could run with a lower JDK, e.g. JavaFX 17 works with JDK 11. But this will change as was mentioned on the mailinglist : “JavaFX 20 requires JDK 17 or later.”
Dirk Lemmermann shared a screenshot in a tweet of the pull requests in the openjdk/jfx project : “Wow, 47 pull requests “ready for review” in #OpenJFX. Looks like we have a traffic jam. Some several years old. Some ending with last comment “can you review this?” 🙂 Hope Oracle really does increase their #javafx team member count.”
At JavaOne on October 20th, some JavaFX related announcements were made.
- A tweet by James Weaver : “Great #JavaFX announcements from @kevinrushforth after being introduced by @mono_quito89 at #JavaOne, while bandmate and @Java legend @BrianVerm mixes drinks. Friend and colleague @johanvos at @GluonHQ highlighted in the process.”
- And a LinkedIn message by Bernard Traversat : “We announced today we will be producing JavaFX build for JDK 20! Providing a modern UI toolkit for the Java platform will continue to make Java the most compelling platform for educators to teach programming and for UI innovators to explore new rich application UI designs.”
- So the latest JavaFX will not only be available on the Gluon website , but also on jdk.java.net/javafx20 .
- Curious what the impact of this announcement will be and what we can share here next week…

SceneBuilder

Chad Preisler shared a video showing how to create a form using SceneBuilder and JavaFX , getting the form to resize the correct way.
Gluon announced the release of Gluon Scene Builder 19 . You can get it from github.com/gluonhq/scenebuilder/releases .
- It incorporates JavaFX 19 wich brings lots of improvements, so you benefit from all these release highlights .
- This tweet shows a video of a bugfix on macOS where copy&paste often resulted in entries doubled after paste. A new preference setting “alternative paste behavior for text input” is available on macOS and is enabled by default.

Devoxx Belgium

Devoxx Belgium (10-14 October) thanks Gluon in a tweet for their continued support for the #OSS Devoxx mobile app. Sources of the DevoxxBadges JavaFX app are available on GitHub .
The tweet wall was a crucial part of the information exchange between the visitors of Devoxx, showing the upcoming talks, highest ranked talks, etc. This tweet wall is a community effort driven by @jugbodensee members, with the support of Gluon, and the sources are on GitHub .
- Johan Vos shared a picture in a tweet .
- By the way (1), TweetwallFX has its own Twitter account @TweetwallFX .
- By the way (2), the official “Devoxx” mobile app is also a JavaFX project, created by Gluon, that you can find on GitHub . Check the GitHub workflows to learn more about how it is building and publishing to the Google and Apple stores .

Various news from “The Web”

Dirk Lemmermann announced in a tweet version 11.12.1 of CalendarFX with new views for displaying resource allocations, improved editing behaviour, plenty of fixes and enhancements. You can find it on GitHub , and new link for the documentation is here .
- Dirk also added a new custom control to GemsFX for displaying screens and windows of a JavaFX application, inspired by MacOS. For a screenshot, check this tweet and a demo is available on YouTube .
- He also announced release 11.12.2 of CalendarFX with various bug fixes related to time zones and recurring entries.
- And he shared this video showing a custom JavaFX control that can be used to display groups of notifications either expanded or as a stack, inspired by the MacOS notification center. However, plenty of customisation options via API or CSS are available to make this control fit into any application.
Robert Ladstätter wanted to use JavaFX on a Windows aarch64 (virtual) machine, and described the process to build it from the sources .
Almas Baim shared a video in a tweet showing a bridge generated with FXGL (game engine) to illustrate a distance joint (which constrains two entities to preserve their distance to each other) that produces some interesting results. Entities with different densities are thrown at it and fly through the screen using physics.
- Related to FXGL: the book “Learn JavaFX Game and App Development with FXGL 17” by Almas Baim got reviewed by Frank Delporte , read it on foojay.io .
OrangoMango shared a project to visualize and solve a Rubik’s Cube with JavaFX , that is also available as an Android APK. It’s inspired by a similar example created by Gluon .
Abhinay Agarwal shared a few very interesting JavaFX links:

Book review: Learn JavaFX Game Development with FXGL 17

Wed, 19 Oct 2022 07:20:32 +0000

This summer, I read the book “Entreprenerd” by Bruno Lowagie . It tells the story of how he started with the iText PDF Java library and turned that into a company together with his wife, and eventually sold it with all problems related to most sales and acquisitions trajects…

In “Entreprenerd,” he also describes the process of writing two books about the iText library itself, as there were no good manuals available, and he wanted to liberate himself from the ever-returning same questions.

JavaFX Links of September

Fri, 30 Sep 2022 08:58:10 +0000

The JavaFX links of the week are back on jfx-central.com , and here we collect the complete month for you in an excellent overview.

JavaFX 19 is released

On the JavaFX mailinglist this thrilling message appeared: “Create release notes for JavaFX 19.” And yes, they are available now on GitHub !
If you want to keep following what’s happening inside the JavaFX community, you can suscribe to the mailinglist via mail.openjdk.org/mailman/listinfo/openjfx-dev .
As with previous releases, the JavaFX community once again succeeded in keeping the 6-months release cycle going on, with a long list of improvements and fixes! The highlights of this release can be found on openjfx.io/highlights/19 .
JavaDoc for JavaFX 19 is available at openjfx.io/javadoc/19 .
An interesting read on InfoWorld lists some of the highlights of JavaFX 19: “JavaFX 19 rich client Java platform arrives” by Paul Krill .
Gluon tweeted an update of the JavaFX roadmap on gluonhq.com/products/javafx .
Johan Vos added the message : “We did our first JavaFX release in September 2018 (JavaFX 11). We planned a 6-months cadence, similar to the JDK releases. Four years later, we still keep the train moving forward. It takes blood, sweat and tears, but seeing what developers are doing with JavaFX makes it worth.”
With a very nice reply of James Gosling (the father of Java! ): “Wonderful! I’m a happy JavaFX user. Thanks for all the wonderful work you do.”

News from “The Web”

Pavlo Iatsiuk announced the first release of DynamoIt — a JavaFX GUI client application for AWS DynamoDB - on Reddit .
- You can find the release on GitHub .
Robert Ladstätter announced the 1000th download of LogoRRR, another JavaFX GUI application!
- This is the Twitter announcement
- The LogoRRR releases can be found on GitHub .
Dirk Lemmermann (of all people…!) got frustrated in this Tweet that he once again had to prove “No, JavaFX is not dead”.
- Let’s all help him in proving a lot of amazing stuff is happening with JavaFX by sharing your project! All contributions are welcome via @jfxcentral on Twitter or a contribution to the jfx-central website on GitHub .
- Dirk also announced in a tweet that CalendarFX will get a whole new suite of controls for displaying “resource” / “resource allocations”.
Pedro Duque Vieira released a new version of JMetro, a JavaFX theme composed by a set of controls, stylesheets and skins, inspired by the Fluent Design System and adapted to fit the JavaFX SDK. There are also changes that have been made according to Pedro’s opinions on some of Fluent Design’s particularities.
- See the Release Notes or sources .
- More info on pixelduke.com/java-javafx-theme-jmetro .
- Pedro also tweeted that he is working on a new controls library, soon to be released. It shows a video of the ListBuilder control with support for drag and dropping of cells .
An interesting discussion in the GitHub maven-jpackage-template project - a project by Will Iverson to provide a template project for native desktop applications. Seems there is often a request for a Spring Boot UI template. Let’s keep an eye on this “BootFX idea” that could be a using the JavaFX embedded web browser.
Friday 30th of September, Gail Anderson is speaking on IntelliJ IDEA Conference about “JavaFX for Mobile Development”. A preview is available on YouTube , hopefully we can share the recording here next time.
Serendipity announced on Twitter SmartFinder 1.5.3 , the first app published on Apple Store with Java 19 and JavaFX 19!
WebFX - a JavaFX to JavaScript transpiler - announced a new demo on their website , based on the excellent DemoFX library by Chris Newman . The demo starts with an introductory animation, asking to click in order to play the actual demo, because in the browser sandbox, playing sound is not permitted before interacting with the user. The resulted demo is just one single java source file. Warning, looking at the demo for too long time can cause brain damage or hypnosis 😉
The demos of the visual modeler, written in JavaFX and integrating OpenCV, by Alessio Vinerbi are really amazing. Look at the video in this tweet where he modifies two videos on the fly with different visual effects.

Wordish with JavaFX - Part 1

Tue, 17 May 2022 10:13:21 +0000

Building Games and Having Fun with Java and JavaFX

Wordish is a JavaFX implementation of the game Wordle. It’s like Wordle. It is Wordle-ish. It’s Wordish. Figure 1. Wordish main layout view

Wordle is a daily online word game. You can play the official Wordle game here:https://www.nytimes.com/games/wordle/index.html . If you haven’t played yet, go check it out.

As I played Wordle, I realized how much fun it would be to create a JavaFX implementation. When you submit a word, each tile rotates to reveal how the individual letter matches – or doesn’t match – the target word. (Ooh, animation!)

Template to Get Started with Pi4J and JavaFX on Raspberry Pi

Thu, 13 Jan 2022 12:07:26 +0000

The Pi4J project wants to be the starting point for everyone who wants to use Java on the Raspberry Pi, being it a headless, JavaFX-user interface and/or GPIO-controller project.

Pi4J is intended to provide a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform . This project abstracts the low-level native integration and interrupt monitoring to enable Java programmers to focus on implementing their application business logic.

Improvements to avoid various crashes on the Raspberry Pi.

Auto-generated Changelog

The full changelog is given below.

JDKMon 17.0.17 Released

Wed, 08 Dec 2021 09:11:22 +0000

JDKMon is a little tool written in JavaFX that tries to detect all OpenJDK distributions installed on your machine and keep track of updates for those distributions.

It will scan for new updates every three hours and will inform you about available updates. JDKMon won’t install the distributions on your machine but will only enable you to download them to a place of your choice.

At the moment the following distributions are supported:

JavaFX Templates for Desktop Applications

Fri, 15 Oct 2021 08:48:16 +0000

Here on Foojay we already talked about JavaFX write-once-run-everywhere applications and how they can be created on GitHub with Gluon and GraalVM:

Creating Mobile Apps with JavaFX by Gail Anderson
Cross-Platform Development in Java with Gluon and GraalVM by Bruno Lowagie
Native Applications for Multiple Devices from a Single JavaFX Project with Gluon Mobile and GitHub Actions by myself

In this post, we are going to take a look at other different approaches.

Getting Started with Java 17 on the Raspberry Pi

Sat, 25 Sep 2021 13:56:53 +0000

As part of the Foojay Virtual OpenJDK 17+ JUG Tour , I was asked to present the state of Java and JavaFX 17 on the Raspberry Pi.

So, a perfect opportunity to freshen up my #JavaOnRaspberryPi presentation with some hot-off-the-press versions.

UPDATE 2021-08-30: the recording of the presentation has been published on YouTube.

In the past, I have been experimenting with Java 16 on the Raspberry Pi (see “Building OpenJDK from GitHub Sources on 64-bit Raspberry Pi ”) but now that version 17 is waiting around the corner, it’s time to prepare our Raspberry Pi for the upcoming new “long-term-supported” (LTS) version.

Announcement: FXGL Game Engine 11.17 Release

Tue, 20 Jul 2021 11:23:27 +0000

The FXGL game engine is now at 11.17. Most of the changes in this release focus on internal code quality and fixes.

Major additions to note:

Added download file API to NetService. Using this API developers can download files from any URL. For example, if certain assets are stored remotely.
Rotation and scale in 3D now support origin points (pivot points). This is a beneficial addition since some animations will need specific origin points for transformations to achieve the desired effect.

Other minor changes include:

How To Get Your JDK As Easily As Possible!

Tue, 20 Jul 2021 07:00:31 +0000

Have you ever been in the situation where you’ve been looking for a specific JDK version of a specific distribution? I think most of us have been there and, I don’t know how you handle this, but in the past I used to save links to distributions in my browser and then I usually I started searching through the vendor website for the package I was looking for.

Sometimes that was easy… sometimes it was hard… but it never was fun. And if you’re used to working with JavaFX, the whole thing got even harder when JDK 11 came out and JavaFX was not bundled with the distribution any longer.

Learn JShell with JavaFX in Only 60 Seconds

Mon, 12 Jul 2021 10:54:56 +0000

Spoon boy : Do not try and bend the spoon. That’s impossible. Instead… only try to realize the truth.
Neo : What truth?
Spoon boy : There is no spoon.
Neo : There is no spoon?
Spoon boy : Then you’ll see, that it is not the spoon that bends, it is only yourself.

– The Matrix, a conversation between Neo and Spoon boy.

In the classic science fiction movie, The Matrix, there’s a cool special effect better known as the falling or raining green code effect. In one scene the character named ‘Cypher’ played by Joe Pantoliano explains how they can monitor activity inside the matrix by looking at the patterns as the code rains down. He claims it’s done this way to simplify seeing people in the matrix than other means due to the fact that there is just way too much data (movie scifi magic talk).

JDKMon: Your Friendly JDK Distribution Updater

Tue, 06 Jul 2021 06:59:15 +0000

I don’t know if you have the same problem but I have around 8 OpenJDK distributions installed on my machine and I always have the problem of keeping them up to date. I know there is sdkman which is awesome but I somehow never got used to it.

Meaning to say I download the OpenJDK distributions manually and install them on my machine. So the main problem is that there so many different distributions out there and all of them have a different way on how to get the latest version. To solve exactly this problem we at foojay.io created the DiscoAPI which keeps track on (hopefully) all available OpenJDK distributions available. Well and because we like to eat our own dogfood I’ve created a little tool that helps me keeping my installed OpenJDK distributions up to date… JDKMon .

Java in Education: Combining Java with Raspberry Pi and the Pi4J Library

Tue, 29 Jun 2021 07:40:55 +0000

The interviews in this post are part of an article published (in German) in Java Magazine . You can get a 25% discount for a new kiosk subscription with the following code: delporte_kiosk25

Although a lot of universities and high schools focus on Python and C# in their program, there are luckily a lot of others who go “full Java”. Don’t get me wrong, I definitely don’t want to start a “programming-languages-war”, but Java is the language I used myself more than any other for the last 10 years. Setting up a new project or building a proof-of-concept for a new idea, is a matter of hours. And there is always a solution for the problem I need to solve. This is probably true for each developer who has enough experience in the language used the most. But having used and experimented with many other languages, I still keep returning to my “one true love”, being Java, as it always delivers the result I’m aiming for, with the right amount of code to be readable, understandable, and testable!

Creating a JavaFX World Clock from Scratch (Part 6)

Fri, 25 Jun 2021 16:48:48 +0000

Wherever you go, no matter what the weather, always bring your own sunshine. – Anthony J. D’Angelo

Hello, and welcome to the last part of this series of articles on creating a JavaFX World Clock from scratch!

In this part, I will show you how to make WebService calls (RESTful) to retrieve weather data based on geographic locations.

If you remember, in Part 5 you learned how to use the JavaFX WebView and the popular mapping library Leaflet JS enabling the user to discover geographic locations. In Part 6, I will show you how I used Java 11’s Http Client to retrieve and display weather content. If you are new to this series, you can visit Part 1 -5 .

Creating Mobile Apps with JavaFX - Part 3

Fri, 25 Jun 2021 09:04:04 +0000

In Part 1 , we introduced a mobile app game, TiltMaze, written completely in JavaFX, which you can download from either the Apple App Store or Google Play and install it on your mobile device or tablet. In P art 2 , we showed you how to work with Gluon and GraalVM to build native images that execute on either Apple or Android mobile devices and tablets.

In this article, we’ll discuss how to upload your application to the respective mobile app stores so the world can install your application on their devices.

Announcing JavaFX: June 2021 Community Update

Mon, 21 Jun 2021 08:22:42 +0000

JavaFX is a modern cross-platform open-source UI toolkit for the JVM. It provides a wide range of built-in controls and platform-specific features, such as hardware acceleration. If you have not used JavaFX before, you can get started at openjfx.io .

In order for any technology to grow and improve, community support and feedback are paramount. To get a general idea of what the community would like to see in JavaFX in the future, I have asked developers to share their thoughts:

Creating Mobile Apps with JavaFX - Part 2

Fri, 18 Jun 2021 07:10:41 +0000

In this article, we’ll discuss the technologies we use with JavaFX to build the JVM byte code version as well as native images that target iOS and Android devices.

GluonFX plugin for Maven

Gluon (https://docs.gluonhq.com/ ) has a Maven plugin that lets you build native-image JavaFX applications targeting multiple platforms. While Java has always been about compiling Java byte code that runs in a Java Virtual Machine (JVM) anywhere and everywhere (Write Once, Run Anywhere), there are prohibitions with running byte code in the mobile environment. Besides the performance penalties of executing byte code in a virtual machine and the relatively long startup time, Apple prohibits JVM applications on mobile targets and Android Java is non-standard. If you choose to leave the JavaFX world for native toolkits, you need to acquire expertise in Objective C/Swift as well as the respective native UI toolkits to target these platforms. Spoiler alert: I didn’t do that!

Getting Started with Game Development Basics with FXGL

Thu, 17 Jun 2021 08:48:28 +0000

Game Development is a large field of Computer Science with a lot of underpinning theory behind the concepts and practices used in the industry. In this short article, we will learn some fundamental basics of these concepts, which will be explored within the context of the FXGL game engine.

However, the concepts themselves are language-agnostic and engine-agnostic. Please note that the material presented here is deliberately simplified to provide a gentle introduction. Those seeking in-depth coverage are encouraged to pursue further research.

Creating Mobile Apps with JavaFX - Part 1

Fri, 11 Jun 2021 07:14:27 +0000

Mobile application offerings for both IOS and Android continue increasing each year .

In this three-part series, I’ll show how to use JavaFX for mobile app development: JavaFX looks great and runs on both mobile platforms.

You use the same JavaFX code targeting Google Play and Apple App stores. Performance is excellent and startup time is fast with native images. You use Java 11+ and the latest JavaFX.

Our game is TiltMaze Labyrinth. Figure 1 shows TiltMaze running on an Android Nexus 5X. Figure 2 shows TiltMaze running on an iPhone 8 Plus.

Gluon Update, Dual Screen Raspberry Pi , IntelliJ JavaFX Project Wizard

Fri, 04 Jun 2021 07:27:41 +0000

Last week, Johan Vos of Gluon, released a video with a status update of JavaFX. In this post we are going to take a deeper look into one of the announcements: dual screen support on Raspberry Pi.

Announcements by Gluon

Since Java switched to a 6-month release cycle, JavaFX has done the same, so next version will be number 17. Keep in mind, although Java and JavaFX are on the same version-number, you can still use Java 11 and combine it with the JavaFX 17 runtime if you want to benefit from its improvements. Up till now, there were no breaking changes in either of the frameworks which force you to use a Java-version higher than 11.

New Java/JavaFX Library FXSkins Released

Thu, 03 Jun 2021 14:02:47 +0000

A new Java / JavaFX library has been released. It’s called FXSkins.

FXSkins is a collection of new Skins for existing JavaFX controls. These Skins will add more functionality to the controls used in your applications with almost no need to make changes to your application’s code.

This library is targeted for the most recent Java versions.

FXSkins Details

FXSkins is a Java / JavaFX library targeted for Java 11 and above, up until the most recent Java version (but should also work with Java 9 and 10). It is currently being built and tested using the current LTS Java version which is Java 11.

Interviews with Robert Savage & Johan Vos on Java on the Raspberry Pi

Fri, 28 May 2021 07:14:26 +0000

This post is part of an article published (in German) in Java Magazine . You can get a 25% discount for a new kiosk subscription with the following code: delporte_kiosk25

Here on Foojay.io, you can find already a long list of articles about Java on the Raspberry Pi . As you may know, already I’m a big fan of this combination. The Raspberry Pi on one side is a very cheap computer that allows you to experiment with electronic components thanks to the Pi4J library. And on the other hand, JavaFX is the ideal framework to build user interfaces that can directly control these components, all in one application!

Welcome to the FXGL Game Engine 11.16 Release

Tue, 25 May 2021 12:10:16 +0000

FXGL is a JavaFX game engine: https://github.com/AlmasB/FXGL

Release Highlights

The restored Multiplayer Service allows easy replications of input, events and entities on a remote machine. For example, by just adding a single line of code (see MultiplayerService API), any key or mouse inputs that occur on one end of the connection can be replicated on the other end.
The new FPS camera allows easy control of the player (or their “line of sight”) in the context of a first-person 3D game.
There is no longer a transitive dependency on the javafx.swing module. This means FXGL users will not need an extra module in their module graph.

Release Notes

Restored and refactored MultiplayerService
Added ReplicationEvent (javafx event that can be replicated on a remote machine)
FPS camera (camera3D.setFPSCamera(true))
Mouse sensitivity setting
Removed dependency on javafx.swing module, thanks to @FDelporte
Performance improvements in Tiled map loading, thanks to @adambocco
isExperimental3D -> 3D
isExperimentalNative -> isNative
Model3D can be loaded from an .obj
Model3D now has a copy()
Added Cuboid shape
EntityGroup::size(), thanks to @adambocco
Allow providing a custom default cursor for all scenes
Internal physics refactoring
Entity no longer throws an exception when adding a duplicate Component (warns instead), thanks to @Zhack47
JavaFX 15 -> 16
Compile target for Kotlin: 1.8 -> 11

Snake Game with JavaFX FXGL in Three Pair-Programming Sessions

Tue, 04 May 2021 07:00:00 +0000

In this article, Almas and I will show you how to start with an idea for a game and bring it to life in a prototype application. We will then modify the application to run on a Raspberry Pi and on a mobile device.

To give some background, some time ago my 10y old son challenged me to create a Snake-like game with emojis. He selected the emoji images and I “only” needed to do the programming bit, the easy part… Luckily Almas asked me if I had a topic for some pair-programming for his YouTube channel , and his question turned into a three-part series. My son is delighted because his idea is now a real game!

Beginning JavaFX Applications with IntelliJ IDE

Wed, 28 Apr 2021 19:33:58 +0000

JavaFX in IntelliJ IDE

This article is for the beginner who wants to get started developing JavaFX applications using Jetbrains’ IntelliJ IDE. The article will create three flavors of a HelloWorld JavaFX application as follows:

Plain - Create a new project from scratch using no build tools
Maven - Create a new project using the Maven build tool
Gradle - Create a new project using the Gradle build tool

While this article may seem elementary for some, I believe it can help newcomers to the JavaFX platform avoid some pitfalls and really hit the ground running.

JavaFX Running in Kiosk Mode on the Raspberry Pi

Tue, 27 Apr 2021 14:39:50 +0000

Combined with an inexpensive touch screen, the Raspberry Pi makes for a perfect controller for a machine or game console. Let’s see how we can use Java and JavaFX to build a test application that also communicates with the pins of the Raspberry Pi to control a LED.

We have done something before already in the post “Light Up your Christmas Tree with Java and Raspberry Pi” , so what’s new here?

Custom Controls in JavaFX (Part VII): JDK Butler

Fri, 12 Mar 2021 09:10:43 +0000

Welcome the final article of this little series about custom controls in JavaFX.

This time, I have created an application that makes use of custom controls. I won’t go through the whole code on how I’ve created this application but only on the custom controls that I’ve created for it.

But first, let me show you the application…

The JDK Butler is an app that makes use of the Foojay Disco API to enable you to drill down to a JDK of your choice and download it to your machine. As you can see in the screenshot, we have columns where we can select things like major version, version, distribution etc.

Custom Controls in JavaFX (Part VI) -- Canvas Class

Fri, 05 Mar 2021 08:21:10 +0000

We are slowly coming to the end of all the different ways in which one can create a custom control in JavaFX. Today I will show you how to create a custom control that is based on the JavaFX Canvas node.

To understand the Canvas node and why it is good to have it, let me briefly explain how rendering in JavaFX is done.

In JavaFX, the so-calledretained mode rendering is used. That means that you, as a developer, don’t have to take care about when to render which area of the screen when you change something (remember rendering artefacts in Swing?). Instead, JavaFX takes care of the rendering of the scene graph. That makes developing applications a lot less complicated because you do not have to track dirty areas and trigger repaints, etc.

Custom Controls in JavaFX (Part V): Region Class

Fri, 26 Feb 2021 08:31:08 +0000

In the last article , I showed you how to create a custom control based on the Control plus Skin approach, which is great for building controls libraries.

This time, I will show you how to create a JavaFX Custom Control that is based on the JavaFX Region class. The Region class is the class that all JavaFX controls are based on. It is a resizable Parent node which can be styled from CSS. This is the class that you would want to use when building a JavaFX custom control that is not part of a controls library.

Custom Controls in JavaFX (Part IV): Control & Skin Classes

Fri, 19 Feb 2021 08:22:35 +0000

I hope you found some time to play around with the custom controls that I showed you in the previous part of this series .

This time, I will show you how to create a custom control in JavaFX by using Control and Skin classes.

A custom control created by a Control and Skin class only makes sense if you will provide more than one Skin for your control or if you would like to give people the ability to create their own Skins for your Control. In any other case, you should choose another approach (e.g., use a Region or Canvas based control).

Custom Controls in JavaFX (Part III) -- Extend an Existing Control

Fri, 12 Feb 2021 08:22:02 +0000

If you’ve been following this series of blog posts, you already read about how to create custom controls by re-styling existing controls or combining existing controls . This time let me show you how to create a custom JavaFX control by extending an existing control.

The goal for today is to create a TextField that looks similar to the TextField that you can find in MaterialDesign .

I use MaterialDesign because it is really popular but be aware that it is not really made for Desktop applications. The reason for this is simple, it needs a lot of space in the vertical direction which makes sense if you keep in mind that it was made for mobile devices where the screen orientation is vertical as where the screen orientation of desktops is horizontal.

Custom Controls in JavaFX (Part II) -- Combining Existing Controls

Fri, 05 Feb 2021 08:23:32 +0000

Last time we saw how to create custom controls in JavaFX by simply playing around with CSS styles for the component.

This time I will show you how to create a custom control by combining existing controls. The idea is to create a control that contains a text field where you can type in values and next to the text field should be a button that when pressed will convert the value from the text field to another value.

How to Use Custom Controls in JavaFX (Part I)

Fri, 29 Jan 2021 08:22:15 +0000

JavaFX is now already some years out in the wild and even if it is not as widely used as web applications, it has its place. It mainly is used in internal applications only, which leads to the impression that nobody is using it.

As long as you only would like to create a simple form-based application, the available UI controls in JavaFX will work totally fine. You need to take a look at how to style the controls using CSS, but from the coding point of view it’s pretty straight forward.

Tips on High Performance Rendering in JavaFX

Mon, 18 Jan 2021 09:07:52 +0000

In this article, we comparatively evaluate four different approaches to render particles in JavaFX in terms of runtime performance.

The approaches are Canvas, PixelBuffer AWT, PixelBuffer CPU and PixelBuffer GPU.

The evaluation suggests the following order of approaches from fastest to slowest:

PixelBuffer GPU (fastest).
PixelBuffer CPU.
PixelBuffer AWT.
Canvas (slowest).

All of the source code developed for this article can be found on GitHub . An example demo with 1 000 000 particles looks like this:

How to Do Device Monitoring with JavaFX and FXGL

Mon, 11 Jan 2021 10:09:21 +0000

In a previous post “Getting Started with FXGL Game Development” we already have taken a look at the FXGL game development framework developed by Almas Baimagambetov .

But, this game engine can also be used for other use cases. In this post, we will be building a system monitoring dashboard, which can run on a Raspberry Pi. The dashboard can be used to keep an eye on any device that can report its state to a queue. And, for me personally, it finally solves the problem of finding the IP addresses of all my Raspberry Pi’s when my router decided to shuffle them… 😉

Java Predictions for 2021: Raspberry Pi and Java

Sat, 26 Dec 2020 09:06:38 +0000

To celebrate the world of Java and predict some highlights for 2021, several key Foojay participants will share their thoughts and hopes during the coming days on Foojay, starting with Frank Delporte, Foojay Community Manager for the Raspberry Pi.

Looking back to my Java adventures in 2020, I can only conclude it has been a wonderful journey.

By writing my book “Getting Started with Java on the Raspberry Pi” (https://webtechie.be/books/ ) and blogging for foojay.io , I discovered Java in the embedded world has a very bright future. With the 6-month release cycle of both Java and JavaFX, a lot of improvements and new features that impact the use of Java on Raspberry Pi, are introduced with every new version.

Native Applications from a JavaFX Project for Multiple Devices

Wed, 25 Nov 2020 08:58:00 +0000

The post “Starting a JavaFX Project with Gluon Tools” shows you how to start a Gluon Mobile Multiview project with a few clicks in IntelliJ IDEA thanks to the “Gluon plugin” .

In this post, we will use such a project and build it with GitHub Actions as a native application for Windows, MacOS, iOS, Linux, and Android from one single code base!

Yes, that’s right!

True “Write Once, Run Everywhere”!!!

The Application

This application is built around a Java library I created last year for my book “Getting Started with Java on the Raspberry Pi” which helps you to calculate the value of a resistor from its color rings. This library is further described on “Resistor color codes and calculations as a Java Maven library” .

We will make a very simple clone of Geometry Wars using FXGL , which is a JavaFX game development framework. You can find the finished project of this post on my GitHub as a Maven project.

Details on OpenJDK vs. OpenJFX Release Cycles

Thu, 29 Oct 2020 14:41:57 +0000

Confused about the release cycles of OpenJDK and OpenJFX and the relationship between them? Read on!

OpenJDK

Since 2018, Java switched to a 6-months release cycle. Every new release brings new finished features, but also “preview” ones which are not finished yet. These can be enabled with a flag (`java --enable-preview`) to allow developers to start experimenting with them and provide feedback to the developers to further improve these so they can become available in one of the next releases.

JavaFX 3D: A Look Back Through History & Some Experiments

Tue, 27 Oct 2020 09:11:30 +0000

After my virtual conference talk “Java and JavaFX on the Raspberry Pi” at the “Oracle Groundbreakers APAC Virtual Tour 2020” , I got in touch with some people who were working on JavaFX 3D in the past, and were curious how that would behave on the Raspberry Pi.

Only one way to find out! Let’s experiment!

History of JavaFX 3D

JavaFX is an open-source, next-generation Java library for rich client applications. JavaFX started with a focus on 2D UI elements.

Spectacular Java Projects on the Raspberry Pi

Java 11 & JavaFX 11 on Raspberry Pi with ARMv6 Processor

Fri, 04 Sep 2020 08:00:39 +0000

In a previous post “Installing Java and JavaFX on the Raspberry Pi ”, you can read how to install BellSoft LibericaJDK to be able to run JavaFX applications with a graphical user interface on a Raspberry Pi with ARMv7 or ARMv8 processor.

But this won’t work for some (older) versions of the Raspberry Pi, as these use an ARMv6 processor, which is not compatible with the default OpenJDK 11 that is part of Raspbian OS.

How to get a JavaFX App on ZuluFX in 60 Seconds

Sun, 23 Aug 2020 06:57:41 +0000

Most Java developers probably know by now that Oracle has open sourced the Java JDK and hosted its source code on Github (aka Project Skara ).

Oracle encourages companies to get paid support for their LTS (Long-term support) versions of the JDK, however for the mass majority of developers (like myself), who still want to enjoy free versions of the latest JDK and JavaFX, we can now get distributions from third-party vendors or build it ourselves (OpenJDK / OpenJFX ).
