[Gtk-sharp-list] Menu.Popup

[McP]

This code works for me:

void MouseClick(object o, ButtonPressEventArgs args)
{
	Gdk.EventButton ev = args.Event;
	...	
	if(ev.button == 3)
	{
		if(popup_menu == null)
		{
			Glade.XML gui = new
Glade.XML(null,"monotageditor.glade","menu1",null);
			popup_menu = (Gtk.Menu) gui["menu1"];
                        ....
		}
                ...                      
		popup_menu.Popup(null,null,null,IntPtr.Zero,ev.button,ev.time);
                        return;
                }
        }
	...
}
