/**
 * A #GtkMenuShell is the abstract base class used to derive the
 * #GtkMenu and #GtkMenuBar subclasses.
 * 
 * A #GtkMenuShell is a container of #GtkMenuItem objects arranged
 * in a list which can be navigated, selected, and activated by the
 * user to perform application functions. A #GtkMenuItem can have a
 * submenu associated with it, allowing for nested hierarchical menus.
 * 
 * # Terminology
 * 
 * A menu item can be “selected”, this means that it is displayed
 * in the prelight state, and if it has a submenu, that submenu
 * will be popped up.
 * 
 * A menu is “active” when it is visible onscreen and the user
 * is selecting from it. A menubar is not active until the user
 * clicks on one of its menuitems. When a menu is active,
 * passing the mouse over a submenu will pop it up.
 * 
 * There is also is a concept of the current menu and a current
 * menu item. The current menu item is the selected menu item
 * that is furthest down in the hierarchy. (Every active menu shell
 * does not necessarily contain a selected menu item, but if
 * it does, then the parent menu shell must also contain
 * a selected menu item.) The current menu is the menu that
 * contains the current menu item. It will always have a GTK
 * grab and receive all key presses.

	 *
	 * The contents of @shell are removed and then refilled with menu items
	 * according to @model.  When @model changes, @shell is updated.
	 * Calling this function twice on @shell with different @model will
	 * cause the first binding to be replaced with a binding to the new
	 * model. If @model is %NULL then any previous binding is undone and
	 * all children are removed.
	 *
	 * @with_separators determines if toplevel items (eg: sections) have
	 * separators inserted between them.  This is typically desired for
	 * menus but doesn’t make sense for menubars.
	 *
	 * If @action_namespace is non-%NULL then the effect is as if all
	 * actions mentioned in the @model have their names prefixed with the
	 * namespace, plus a dot.  For example, if the action “quit” is
	 * mentioned and @action_namespace is “app” then the effective action
	 * name is “app.quit”.
	 *
	 * This function uses #GtkActionable to define the action name and
	 * target values on the created menu items.  If you want to use an
	 * action group other than “app” and “win”, or if you want to use a
	 * #GtkMenuShell outside of a #GtkApplicationWindow, then you will need

	 * then you would use the action name “mygroup.quit” in your
	 * #GMenuModel.
	 *
	 * For most cases you are probably better off using
	 * gtk_menu_new_from_model() or gtk_menu_bar_new_from_model() or just
