Hi Miguel,

This piece of code should work for you:


this.appWindow.DeleteEvent += new Gtk.DeleteEventHandler
(OnDeleteEvent);


void OnDeleteEvent (object o, DeleteEventArgs args) {
        if (contentsModified == true) {
		new WarningDialog();
	}

        Application.Quit();
        args.RetVal = false;
}

The problem might be in WarningDialog(), how do you display your dialog?
If it's a normal window, the program will quit right away.. 
If that is the case, try to use use a MessageDialog and call Run() on
the dialog...
