[flexcoders] how to add nativemenu on topLevelApplication

[isa_loyer]

I developp a AIR application.

I try to add menu on it.

My application has custom chrome, and I like to have a transparent background 
on main application.

Today, I insert the nativemenu on a native window:

 FlexGlobals.topLevelApplication.visible = false;
                var options:NativeWindowInitOptions = new 
NativeWindowInitOptions(); 
                options.systemChrome = NativeWindowSystemChrome.STANDARD; 
                options.transparent = false; 
                options.maximizable= false;
                options.resizable = false;
                menuWindow = new NativeWindow(options); 
                menuWindow.width = Capabilities.screenResolutionX; 
                menuWindow.height = 55; 
                menuWindow.x = 0;
                menuWindow.y = 0;


                menuWindow.title = "MyApp";
                menuWindow.menu = menuBarSE.initMenuOE();
                menuWindow.alwaysInFront = true; 
                menuWindow.activate();   
                menuWindow.addEventListener(Event.CLOSING, 
applicationExitHandler);

But, with this approach is difficult to manage other window, like reduce or 
maximize action.

So, if it's possible I'd like to add the menu on the main window 
(topLevelApplication), but I don't know how!

If someone could help me.

thanks
