MenuToolkit returns null under MacOSX

[fujohnwang]

I am developing under Mac, when I create a simple demo javafx application, it's ok.

when I put same logic code into another javafx application, I failed with exception below:

2020-11-21 10:04:11,463 INFO  [main] c.k.keebox.KeeboxFXApplication$ - Starting KeeboxFXApplication. using Java 15 on fq16.lan with PID 18369 (/Users/fq/workspace.keevol/KeeboxNative/target/classes started by fq in /Users/fq/workspace.keevol/KeeboxNative)

    at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:96)

the code part is:

    val scene = new Scene(layout)
    scene.getStylesheets.add(getClass.getResource("/css/style.css").toExternalForm)
    stage.setScene(scene)

    val tk = MenuToolkit.toolkit(Locale.getDefault). 
    tk.setApplicationMenu(tk.createDefaultApplicationMenu("KEEBOX", stage)). // <<<<<<--here

    stage.setTitle("KEEBOX")
    stage.getIcons.add(Images.LOGO)
    stage.show()

I debug into the code , found isSupported() returns false and then everything return null.

But it doesn't make sense, and I don't know why. The only difference between these two application is in the latter, I run springboot first and launch javafx second, But I don't think that's culprit for isSupported return false.

any hint?

I trace here which doesn't make sense:

private static AdapterContext createContext() {
    if (!Toolkit.getToolkit().getSystemMenu().isSupported()) {
      return null;
    }

I found why, the AWT thing broke it.

I use AWT for system tray ...

Hi, thanks for sharing. Returning null is obviously not so nice there... I'm currently rewriting this mechanism, so hopefully we won't run into situations like this anymore.

You may want to give the latest update a try. Please refer to https://github.com/codecentric/NSMenuFX/issues/36 for detail
