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 during October.


  • 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 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!".


  • Version 21 is now available!
    • Refactored: Clean up DocumentWatchingController
    • Uses JDK and JavaFX 21
    • Contributors:
      • Abhinay Agarwal
      • Almas Baim
      • José Pereda
  • Scene Builder 21.0.1 RC1 is available for testing.



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.
    • See the DateRangePicker control in action here.
  • JPro announced version 2023.3.0: JavaFX 21 is used by default, and many more improvements!
    • And version 2023.3.1 with a critical bugfix to handle bot traffic better, and a new feature regarding MimeTypes.

Podcast, Video, Books


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


  • 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."
