Hi!

Currently i try to inject my main menu in a handler. main reason for this is, to hide the main menu on a specific shortcut. the shortcut->command->handler mapping works fine, but only if I not try to inject the main menu. here is my handler implementation:

public class HideMenuHandler {
	@Inject
	@Named("menu:org.eclipse.ui.main.menu")
	private MMenu menu;
	
	@Execute
	public void execute(@Named(IServiceConstants.ACTIVE_SHELL) Shell shell) {
		System.out.println("menu");
	}
}

if i implement my handler like above, the execute method is not called. on some examples i've seen, this technique is only used in processor's. how i can get the mmenu (main menu) in to my handler?

thank you

Do NOT use @Inject in Handlers put everything you need into the
execute()-method.

I'm not sure on the ID you are using but if it is not working I'd
suggest you let yourself inject the window instance and navigate to the
Menu from there.

Hi Tom,

ok, i've tried the following suggestion:

@Execute
	public void execute(MApplication application, EModelService service){
		//myTrimmedWindow
		List<MTrimmedWindow> findElements = service.findElements(application, "myTrimmedWindow",
				MTrimmedWindow.class, null);
		findElements.get(0).getMainMenu().setVisible(false);
		findElements.get(0).getMainMenu().setEnabled(false);
	}

the Window is there, the MainMenu too. but none of the both methods (setVisible & setEnable) works. do i miss something?

thank you for your help Smile

Hi,

Hm looking at the code I see that the renderer hooks itself up
visibility changes. Now my wild guess that the case for the Root-Menu
(==MenuBar on the Shell) is not implemented.

I'd suggest to file a bug for this so that we can track why your code is
not working.
