27 * @Title: GtkMenuShell
28 * @Short_description: A base class for menu objects
30 * A #GtkMenuShell is the abstract base class used to derive the
31 * #GtkMenu and #GtkMenuBar subclasses.
33 * A #GtkMenuShell is a container of #GtkMenuItem objects arranged
34 * in a list which can be navigated, selected, and activated by the
35 * user to perform application functions. A #GtkMenuItem can have a
36 * submenu associated with it, allowing for nested hierarchical menus.

87 * A menu item can be "selected", this means that it is displayed
88 * in the prelight state, and if it has a submenu, that submenu
91 * A menu is "active" when it is visible onscreen and the user
92 * is selecting from it. A menubar is not active until the user
93 * clicks on one of its menuitems. When a menu is active,
94 * passing the mouse over a submenu will pop it up.
96 * menu_shell->active_menu_item, is however, not an "active"
97 * menu item (there is no such thing) but rather, the selected
98 * menu item in that MenuShell, if there is one.
100 * There is also is a concept of the current menu and a current
101 * menu item. The current menu item is the selected menu item
102 * that is furthest down in the hierarchy. (Every active menu_shell
103 * does not necessarily contain a selected menu item, but if
104 * it does, then menu_shell->parent_menu_shell must also contain
105 * a selected menu item. The current menu is the menu that
106 * contains the current menu_item. It will always have a GTK
107 * grab and receive all key presses.
112 * ::move_current (GtkMenuDirection *dir)
113 * Moves the current menu item in direction 'dir':
115 * GTK_MENU_DIR_PARENT: To the parent menu shell
116 * GTK_MENU_DIR_CHILD: To the child menu shell (if this item has
118 * GTK_MENU_DIR_NEXT/PREV: To the next or previous item
121 * As a a bit of a hack to get movement between menus and
122 * menubars working, if submenu_placement is different for
123 * the menu and its MenuShell then the following apply:
125 * - For 'parent' the current menu is not just moved to
126 * the parent, but moved to the previous entry in the parent
127 * - For 'child', if there is no child, then current is
128 * moved to the next item in the parent.
130 * Note that the above explanation of ::move_current was written
131 * before menus and menubars had support for RTL flipping and
132 * different packing directions, and therefore only applies for
133 * when text direction and packing direction are both left-to-right.
135 * ::activate_current (GBoolean *force_hide)
136 * Activate the current item. If 'force_hide' is true, hide
137 * the current menu item always. Otherwise, only hide
138 * it if menu_item->klass->hide_on_activate is true.
141 * Cancels the current selection
