*
|
|
* 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.
|
|
*
|
|
* menu_shell->active_menu_item, is however, not an "active"
|
|
* menu item (there is no such thing) but rather, the selected
|
|
* menu item in that MenuShell, if there is one.
|
|
*
|
|
* 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 menu_shell->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.
|
|
*
|
|
*
|
|
* Action signals:
|
|
*
|
|
* ::move_current (GtkMenuDirection *dir)
|
|
* Moves the current menu item in direction 'dir':
|
|
*
|
|
* GTK_MENU_DIR_PARENT: To the parent menu shell
|
|
* GTK_MENU_DIR_CHILD: To the child menu shell (if this item has
|
|
* a submenu.
|
|
* GTK_MENU_DIR_NEXT/PREV: To the next or previous item
|
|
* in this menu.
|
|
*
|
|
* As a a bit of a hack to get movement between menus and
|
|
* menubars working, if submenu_placement is different for
|
|
* the menu and its MenuShell then the following apply:
|
|
*
|
|
* - For 'parent' the current menu is not just moved to
|
|
* the parent, but moved to the previous entry in the parent
|
|
* - For 'child', if there is no child, then current is
|
|
* moved to the next item in the parent.
|
|
*
|
|
* Note that the above explanation of ::move_current was written
|
|
* before menus and menubars had support for RTL flipping and
|
|
* different packing directions, and therefore only applies for
|
|
* when text direction and packing direction are both left-to-right.
|
|
*
|
|
* ::activate_current (GBoolean *force_hide)
|
|
* Activate the current item. If 'force_hide' is true, hide
|
|
* the current menu item always. Otherwise, only hide
|
|
* it if menu_item->klass->hide_on_activate is true.
|
|
*
|
|
* ::cancel ()
|
|
* Cancels the current selection

|
* the menu doesn't work. Consequently, keynav on the menu will only
|
|
* work if the focus is on some toplevel owned by the onscreen keyboard.
|
|
*
|
|
* To avoid confusing the user, menus with @take_focus set to %FALSE
|
|
* should not display mnemonics or accelerators, since it cannot be
|
|
* guaranteed that they will work.
