Java(FX): How can I edit the menu items of the standard mac os x menu bar?

Question

I'm developing a Java(FX) application and like to change the title of my application in the standard menu item of every application (see the screenshot). I also want to set an own behavior for the About and Preferences menu items, but they arn't there.

I know, that this is possible in swing, but how it is possible with! JavaFX?

Answer 1

You can use NSMenuFX to do this. Here is an example on how to create an About menu:

NSMenuBarAdapter adapter = new NSMenuBarAdapter();

// Get the default menu bar as JavaFX object
MenuBar menuBar = adapter.getMenuBar();

// Create a new menu item
MenuItem about = new MenuItem("About");

about.setOnAction(new EventHandler<ActionEvent>() {
  @Override
  public void handle(ActionEvent event) {
    // Open a new JavaFX dialog
  }
});

// Add the menu item as first element to the application menu
menuBar.getMenus().get(0).getItems().add(0, about);

// Update the menu bar
adapter.setMenuBar(menuBar);
