--
-- This widget represents one of the lines in a menu, on which the user can
-- click to execute an action. The menu items can be bound to a submenu, so
-- that clicking on them will in fact display the submenu on the screen.
--
-- They can also be associated with key shortcuts (called accelerators). See
-- the subprogram Set_Accel_Path, and the subprograms in the package
-- Gtk.Accel_Map.
--
-- Activating the proper options in the theme files will allow the user to
-- interactively modify the shortcuts.

-------------
-- Signals --
-------------
--
-- The following new signals are defined for this widget:
--
-- - "activate"
-- procedure Handler
-- (Menu_Item : access Gtk_Menu_Item_Record'Class);
-- Emitted when the menu item has been activated, ie the user has clicked
-- on it (or use a key shortcut for this)
--
-- - "activate_item"
-- procedure Handler
-- (Menu_Item : access Gtk_Menu_Item_Record'Class);
-- ???
--
-- - "toggle_size_request"
-- procedure Handler
-- (Menu_Item : access Gtk_Menu_Item_Record'Class;
-- Request : Gtk_Requisition_Access);
-- Query the menu item to ask for its preferred size (this might not be
-- the one actually allocated for it, depending on screen space)
--
-- - "toggle_size_allocate"
-- procedure Handler
-- (Menu_Item : access Gtk_Menu_Item_Record'Class;
-- Allocation : Gtk_Allocation_Request);
-- You should emit this signal to allocate a specific size for the item.
-- In practice, you will not need to do this yourself, since gtk+ takes
-- care of it correctly most of the time.
--
--
--
-- If you want to get a signal every time the menu item is made visible
-- on screen, for instance because you want to dynamically set its
-- sensitive state, you should connect to the "map" signal of the
-- toplevel menu, as in:
-- Gtkada.Handlers.Widget_Callback.Object_Connect
-- (Get_Toplevel (Item), "map",
-- Slot_Object => Item);

procedure Gtk_Select (Menu_Item : access Gtk_Menu_Item_Record);
-- Emits the "select" signal on Menu_Item
procedure Deselect (Menu_Item : access Gtk_Menu_Item_Record);
-- Emits the "deselect" signal on Menu_Item
procedure Activate (Menu_Item : access Gtk_Menu_Item_Record);
