What I see in ./applemenu/src/org/netbeans/modules/applemenu/layer.xml is that
the generic action is hidden on macOS:
<!-- Hide menu items that belong on Apple's app menu -->
<folder name="Actions">
<folder name="Window">
<file
name="org-netbeans-core-windows-actions-ToggleFullScreenAction.instance_hidden"/>
</folder>
</folder>
That's why you are getting a null.
So, there is no API to call that action on macOS as far as I can tell.
This workaround does the trick (inspired by
https://gist.github.com/dohpaz42/4200907 ):
@SuppressWarnings({"unchecked", "rawtypes"})
public static void requestToggleFullScreen(Window window)
{
try {
Class appClass = Class.forName("com.apple.eawt.Application");
Class params[] = new Class[]{};
Method getApplication = appClass.getMethod("getApplication",
params);
Object application = getApplication.invoke(appClass);
Method requestToggleFulLScreen =
application.getClass().getMethod("requestToggleFullScreen", Window.class);
requestToggleFulLScreen.invoke(application, window);
} catch (Exception e) {
System.out.println("An exception occurred while trying to toggle
full screen mode");
}
}
requestToggleFullScreen(Frame.getWindows()[0]);
