Here is the overview of the JavaFX LinksOfTheMonth of July 2024, published on jfx-central.com during this month. Core A message by Kevin Rushforth on the openjfx-dev@openjdk.org mailing list shows the Java/JavaFX release train is approaching the next station ;-): “Bump the version number of JavaFX to 24. I will integrate this to master as part of forking the jfx23 stabilization branch, which is scheduled for Thursday, July 11, 2024 at 16:00 UTC.
Last week I was working on a blog post 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.
Here is the overview of the JavaFX LinksOfTheMonth of June 2024, published on jfx-central.com during this month. Core New JavaFX 23 Early-Access Builds are available on jdk.java.net/javafx23. Friedhold Matz shared a screenshot showing that WebView in JavaFX 22 now works with GraalVM 22+36.1. Applications Christopher Schnick shared screenshots: “XPipe 9.4 comes with a JavaFX markdown view for notes that works through the WebView.
In the next video in this “JFX In Action” series, I talked with Robert Ladstätter about LogoRRR, an application written with Scala and JavaFX. About Robert Ladstätter Robert is Group Leader for the Software Team at Nextsense GmbH (part of Hexagon) and develops software with Scala and JavaFX. You can find him on Twitter and LinkedIn.
In the next video in this “JFX In Action” series, I talked with Christopher Schnick about XPipe. About Christopher Schnick Christopher is a software engineer with experience in the Java ecosystem and desktop application development. He is passionate about designing innovative solutions for end users and learning new technologies and tools when needed.
For the second video in this “JFX In Action” series, I talked to Daniel Zimmermann. He got my attention when he recently tweeted: “To your dismay I have to tell you I write all my desktop applications using Kotlin and JavaFX”. Why is he a big Kotlin AND JavaFX fan? I asked him and got a demo of the network test application that he is working on.
People who follow me, know I have a big love for JavaFX. It’s my go-to for every desktop user interface application I build. I love the simplicity of quickly creating an app that makes full use of the “Java powers” to build both multi-threaded “backend services” combined with a beautiful-looking UI into one executable.
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.
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.
Here is the overview of the JavaFX LinksOfTheMonth of April 2024, published on jfx-central.com during this month. Core Gluon published new releases of JavaFX: 22.0.1 and the LTS releases 17.0.11 and 21.0.3. You can get them from Maven Central and the Gluon website. The new builds of Java and JavaFX, that were released this week, contain several fixes related to Common Vulnerabilities and Exposures (CVE), see for example the release notes of Azul Zulu.
Here is the overview of the JavaFX LinksOfTheMonth of March 2024, published on jfx-central.com during this month. Components, Libraries, Tools Pedro Duque Vieira integrated this pull request in FXThemes: “True Dark Mode is now also available on Mac. All thanks to Carl Dea. Not new, but siedlerchr pointed us on EasyBind: “Leverages lambdas to reduce boilerplate when creating custom bindings, providing a type-safe alternative to Bindings.
At the Fosdem conference in Brussels on February 3rd, I gave a presentation about using an existing documentation set as the data for a ChatGPT-like application, created with JavaFX and LangChain4J. The video and links of that presentation are available here, and this post is a more detailed explanation of that application.
Here is the overview of the JavaFX LinksOfTheMonth of February 2024 that got published on jfx-central.com during this month. Core Christopher Schnick shared a video: “The JavaFX 22 platform preferences API in action. You can now query and observe the system color schemes.. Gluon announced that new EA releases for the upcoming JavaFX 22 (22-ea+28) and JavaFX 23 (23-ea+3) platforms are available for download from gluonhq.
These are all the links of my presentation at the Fosdem Conference in Brussels, Saturday, February 3th, 2024, 17:40 CET. Experimenting with AI and LLM to make docs searchable through a chat application ChatGPT is considered to bring the end to search engines. But it’s also a pretty good liar, just making stories up.
This is the first JavaFX LinksOfTheMonth review for 2024, an overview of the LinksOfTheWeek that got published on jfx-central.com during January. Core JavaFX 21.0.2 (January 2024) is available on the Gluon website. Applications Robert Ladstätter added ZIP file support to LogoRRR: “No more unzipping before analysing your latest bugs from ops!
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.
I had a lot of interesting talks with Java experts since I started producing the Foojay Podcast. But when I asked the organizers of the J-Fall conference, if I could do some kind of live broadcast at their event, I hadn’t imagined it would be such an amazing experience! During the day I had 29 interviews, which I all broadcasted live on multiple websites (YouTube, LinkedIn, and Twitter) with the amazing restream system.
FXGL is a framework to easily create JavaFX-based game applications. In this blog post, I want to show you how this can be done within a single Java-file which doesn’t need a full Maven or Gradle project but can be executed directly with JBang without compilation. This approach can be used as an easy way to get new Java(FX) developers started or create your first experiments with FXGL.
Have fun with this overview of the “JavaFX LinksOfTheWeek” that got published on jfx-central.com during November. Core Carl Dea shared: “JavaFX 22 will be supporting platform specific settings! E.g. dark and light mode etc.”. See JDK-8319138: Platform preferences API. Also worth following: JDK-8305116: “Frosty / Milky / diffuse transparency areas showing desktop background” Dirk Lemmermann is looking forward to the next release of JavaFX: “We can hope to see CSS transitions, themes, and Platform API (dark mode, accent colors).
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.
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.
This month OpenJDK and OpenJDK 21 got officially released, so links to the new downloads but also to the early access builds of the next one! Here is the overview of the JavaFX LinksOfTheWeek that got published on jfx-central.com during September. Core Announcement by GluonHQ: “We’re proud to announce JavaFX 21 GA.
Just like Foojay wants to be 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.
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.
Yes, the Raspberry Pi Operating System is awesome! But the Pi4J project made it if 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.
Although I skipped a few weeks because of busy schedules, holiday interruptions, and too few hours in a day, there was still a lot to report in the two #LinksOfTheWeek that were published on jfx-central.com in July. Have fun reading and clicking, and see you end of August for one long #LinksOfTheMonth…
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.
Writing has always been my passion, and even in my previous jobs as a developer, I stood out as the one who enjoyed creating and maintaining documentation. But June 9th, 2023, marked my first birthday as a full-time technical writer at Azul. Yes, it’s already a year ago that I changed from being a developer-who-also-writes to a writer-who-also-develops.
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.
Some time ago on Twitter, I discovered @OrangoMango, 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?
This is the summary of the #LinksOfTheWeek as published on jfx-central.com. JavaFX Core Gluon announced JavaFX update releases: 20.0.1 (latest release), 17.0.7 (latest LTS), and for Gluon LTS customers 11.0.19. In this video with Kevin Rushforth he talks about JavaFX 20 and beyond. Dirk Lemmermann tweeted some of the highlights like RichTextArea, ideas for future releases,… The Notebook demo is looking really nice to learn JavaFX in an easy way.
On Foojay.io, Bazlur Rahman is publishing a series of interviews with various people from the OpenJDK community. I had the honor to be included in this series, and this is a repost. Welcome to our exclusive interview with Frank Delporte, a Senior Technical Writer at Azul, Java Champion, and a passionate advocate for all things related to Java and Java on Raspberry Pi.
This is the summary of the #LinksOfTheWeek as published on 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.
February is a short month, but this list seems to be longer than ever… A lot of game development, releases, interesting ongoing development, and so much more to read. Enjoy reading and clicking! This is the summary of the #LinksOfTheWeek 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).
2023 has taken off with a flying start in JavaFX-world! Here is a summary of the Links Of The Week that were published in January on jfx-central.com. JavaFX Versions Gluon announced the first set of JavaFX releases in 2023: JavaFX 19.0.2: public release containing some updates and security patches to JavaFX 19.
If anyone needs a reminder Java and JavaFX are “alive and kicking”, you can not only check out jfx-central.com, but also the list below. Although I’m trying to get of Twitter - for my own mental health 🙂 - I’m still being flooded with amazing content. Here is the result of the #LinksOfTheWeek that were published on jfx-central.
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.
After my talk at J-Fall I got the question what is required to get started with #JavaOnRaspberryPi. In my book I list the components that are used, but indeed a short overview was missing (it’s now added to the ebook…). So here we go: Raspberry Pi While working on the book, I used a Raspberry Pi 3.
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.
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.

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.
On the OpenJFX website you can find a lot of getting started documentation. But as one image/video says more than a thousand words, I created this short movie to show you that creating a new JavaFX project is just a matter of a few clicks with the JetBrains IntelliJ IDEA.
As part of the Pi4J project, we created an example game with JavaFX and FXGL that uses an Arcade kit with a Joystick and big push buttons. The test setup for this project was kicking around my desk, so that was the perfect victim for my next 3D printing project…
In the previous post we started our discovery of HiveMQ Cloud with Java on the Raspberry Pi. We created an application to send measurements of various sensors to the HiveMQ Cloud MQTT broker. Using an online websocket client we verified the transition of the messages, and could see the data being published to this online message queue.
The Raspberry Pi in combination with an inexpensive touch screen, makes a perfect controller for a machine or game console. Let’s see how we can use Java and JavaFX to build a test application which 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?
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.
Today I could give my talk “Having fun with Java and JavaFX on the Raspberry Pi” at the JFXDays. Normally this event takes place in Zurich, but this year also went virtual because… well because of 2020… I’m honored that my talk was part of this two-day event with a lot of talks by all the people who are the driving forces in the JavaFX community!
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!
On foojay.io you can already find two posts by Carl Dea to get you started with JavaFX: Beginning JavaFX Applications with IntelliJ IDE: step-by-step how to start a new JavaFX project without any tools, are by using the Maven and Gradle tools. A JavaFX App on ZuluFX in 60 Seconds: how to use a popular distribution from Azul to build a JavaFX HelloWorld Application in 60 seconds.
Today I had my first Devoxx talk, after my Java virtual talk a few weeks ago at the “Oracle Groundbreakers APAC Virtual Tour 2020” conference (21/10)! The event in Ukraine also went virtual which gave me the opportunity to share my love for Java, JavaFX and the Raspberry Pi again.
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.
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!
Today I had the honor to speak at the “Oracle Groundbreakers APAC Virtual Tour 2020” conference. And of course the title of my talk was “Java and JavaFX on the Raspberry Pi”. Video (start at 3'05") Links mentioned during the talk (in order) Passendale, Belgium Televic Rail - Passenger Information Systems CoderDojo Book: “Getting Started with Java on the Raspberry Pi” Raspberry Pi Announcing Raspberry Pi Compute Module 4 Raspberry Pi Compute Module 4 on sale now from $25 TIOBE Index Which Programming Languages Use the Least Electricity?
Thanks to Twitter and LinkedIn I got into contact with several developers who are doing Java stuff on Raspberry Pi and I want to share those projects with you as they can be an inspiration for all of us to get started with Java development on the Raspberry Pi. Igor Souza - Kafka on the Raspberry Pi Igor shared this nice video where he set up a Kafka cluster on Raspberry Pi.
For this post I did some experiments with Java 15, reusing the Ubuntu 64bit SD card which was also used for the earlier post “Comparing a REST H2 Spring versus Quarkus application on Raspberry Pi”. That version of Ubuntu comes with OpenJDK 11 pre-installed. $ java -version openjdk version "11.0.8" 2020-07-14 OpenJDK Runtime Environment (build 11.
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 which is part of Raspberry Pi OS.
FXGL is a Java, JavaFX and Kotlin Game Library (Engine) made by Almas Baimagambetov. As my son (almost 10y) challenged me to make a game during my “Corona-stay-at-home-time”, I had the luck Almas provided me a getting-started with this detailed step-by-step. For a more up-to-date and extended example, check this newer post of 2023/12/14 A JavaFX Game Application in a Single Java File with JBang and FXGL.
One of the most read articles on this blog is about the installation of a recent Java on Raspberry Pi (March 13, 2019), so it’s time for an update! Disclaimer: this article is only valid for Raspberry Pi’s with an ARMv7 or ARMv8 processor. In the Raspberry Pi specifications table on Wikipedia you get a clear overview of the Pi-types with this processor:
Based on multiple examples from my book “Getting started with Java on Raspberry Pi”, I created a touchscreen controller for the drum booth of my son. Combined with relays boards and an Arduino this allows to control LED strips and different lights with a touch screen interface. There is also a web server included so we can trigger some events from anywhere in the house through a webpage so we don’t need to yell anymore from down the stairs when food is on the table ;-)
In my book I explain the use of bits and bytes by using a shift register SN74HC595 IC and 5101AS LED number display. A number display with LED segments Defining the bytes for each number In the table below the bits are defined to get the hex/number value needed to light up the required segments (A - H) of the LED segment display:
To create some timeline images for my book, I created this little JavaFX application to be able to easily update the content and recreate the image. Of course you can do the same in an image editor, but hey I’m a programmer and lazy, so I want a program to do the job for me ;-)
Using the Java library I created (see previous post), it was a piece of cake to create a JavaFX UI on top of it! Source The sources are part of the GitHub project which contains all the other examples, scripts, readmes and a lot more which are used in the book to explain Java, JavaFX, Maven, Raspberry Pi GPIO’s…
Next step in my book progress, is getting more into the details of hardware components. And as always starting with the smallest most-used ones: resistors! To be able to fully document this for the book and create a demo application, I started again with creating and sharing a Java library.
One of the example applications in my book “Getting started with Java on the Raspberry Pi” combines a JavaFX application with Mosquitto on the Raspberry Pi to control a LED strip with an Arduino. All wireless and independent of each other as the Mosquitto-queue is dealing with exchange commands between all applications.
My very first open source JavaFX library is now available in the Maven repository! A small step for mankind, one giant leap for myself ;-) While working on Java example projects for my book “Getting started with Java on Raspberry Pi”, I needed a way to visualize a LED number display as used in electronics projects.
While trying out what Pi4J can do, I found it could easily be extended with a JavaFX application to provide info about the headers on a Pi board. This could later be extended to a remote/local (touch) User Interface using the REST interface from this post. Starting point I started with the minimal JavaFX application I created before for a quick start with the correct pom.
As my daily work mainly is Java and back-end stuff on “real servers”, I set myself for 2019 as a personal goal to experiment with Java 11 on a Raspberry PI. While doing so, I needed multiple scripts and test projects. And because I strongly believe in “learning by sharing”, this resulted in a blog series with links to the sites and people who inspired and helped me, plus the sources on my GitHub account.
What we will do Based on the previous blog posts we can install and run Java 11 we have a minimal JavaFX 11 application which runs fine on a PI So there is one “small” step remaining: build something which actually does something on the PI, talking to the GPIO’s and show what’s happening.
In part 2 of this blog series Java 11 was successfully installed on a PI. And in part 4 a running Java FX jar was generated on a PC. Time to move back to the PI… Run the JavaFX .jar application Make sure you have a the Liberica Java JDK installed as described in part 2 as JavaFX is not part of the “normal” Java JDK.
I prefer a Java app above a web app, because starting a new “modern” web development requires you to pull a bunch of dependencies and a lot of files before you can start. While Java just needs the JDK and one Java file, even on a Raspberry PI (as described in PiJava - Part 2).
What is JavaFX? From the Oracle site: “JavaFX is a set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that operate consistently across diverse platforms.” JavaFX was originally created by Sun Microsystems, later became part of Oracle Corparation and is now an open source project on openjfx.
