/**
 * Description
 * A GtkMenu is a GtkMenuShell that implements a drop down menu consisting of
 * a list of GtkMenuItem objects which can be navigated and activated by the
 * user to perform application functions.
 * A GtkMenu is most commonly dropped down by activating a GtkMenuItem in a
 * GtkMenuBar or popped up by activating a GtkMenuItem in another GtkMenu.
 * A GtkMenu can also be popped up by activating a GtkOptionMenu.
 * Other composite widgets such as the GtkNotebook can pop up a GtkMenu
 * as well.
 * Applications can display a GtkMenu as a popup menu by calling the
 * gtk_menu_popup() function. The example below shows how an application
 * can pop up a menu when the 3rd mouse button is pressed.
