What menu are you talking about here? If this is about popup menus, e.g. right click menu, "hamburger" menu, etc, these are all surfaces drawn by the client (yourself), and mapped using "xdg_popup" role (part of the xdg-shell protocol extension). If this is about the "window menu" which is usually what shows up when you right click on the title bar, this is (optionally) drawn by the compositor, e.g. done by kwin or gnome-shell. This menu is shown by the client issuing the "show_window_menu" request on the xdg_toplevel object. Jonas
