Recently I wanted to check that I was current with Scene Builder, but there was no about item with the version. I looked at this some time back. https://marc.info/?l=openjdk-openjfx-dev&m=167391490829873&w=2 I did this, incomplete as a lot of my stuff is, after the following note. https://github.com/mik3hall/JavaFXDesktop On Jan 6, 2023, at 4:35 PM, Michael Hall <mik3h...@gmail.com> wrote: I haven’t verified if this would further allow changing the java.awt.Desktop about handler. I did check that custom AboutHandlers are possible for OS/X JavaFX applications. With… static { //java.awt.Toolkit.getDefaultToolkit(); // Start AppKit Thread t = new Thread(() -> { java.awt.Toolkit.getDefaultToolkit(); }); t.start(); } I made the Application class itself the handler… public class HelloWorld extends Application implements AboutHandler { Setting the handler seemed to also need some thread management. @Override public void init() { Thread t = new Thread(() -> { Desktop desktop = Desktop.getDesktop(); desktop.setAboutHandler((AboutHandler)this); }); t.start(); } It appeared this could be done in the init or about anywhere in the javaFX start method. The handler I think comes in on the AWT EventQueue so needs to be changed to javaFX public void handleAbout(AboutEvent evt) { System.out.println("got to handleAbout"); Platform.runLater(() -> { Alert alert = new Alert(AlertType.INFORMATION, "About HelloWorld"); alert.showAndWait(); }); } Checking on Windows 10 VirtualBox it appeared Desktop.Action.APP_ABOUT isn’t supported. I had trouble with my VirtualBox linux images so didn’t verify there but I’m guessing this is viewed as OS/X only and not supported there either. I never really did determine why javaFX applications are different. My last thought had been that they instantiated an NSApplication early so a NSApplicationAWT wss never obtained. However, I later thought I saw where I passed a check indicating I had to have NSApplicationAWT. With a fix so you get the About menu item it seemed a little moot. What I provided for ApplicationDelegate seems to be one such fix. You can come up with your own fix but I think it will need to done jdk side though to provide this functionality to javafx app’s. I might bring this up on the javafx list if the jdk does make it possible at some point. I haven’t looked at any other Desktop functionality for javafx app’s yet having no immediate need myself.
