[−]Struct gtk::MenuShell
A MenuShell
is the abstract base class used to derive the
Menu
and MenuBar
subclasses.
A MenuShell
is a container of MenuItem
objects arranged
in a list which can be navigated, selected, and activated by the
user to perform application functions. A MenuItem
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.
