MenuShellRef

public struct MenuShellRef : MenuShellProtocol, GWeakCapturing

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 MenuShellRef type acts as a lightweight Swift reference to an underlying GtkMenuShell instance. It exposes methods that can operate on this data type through MenuShellProtocol conformance. Use MenuShellRef only as an unowned reference to an existing GtkMenuShell instance.
