Interfaces

GtkMenuItem implements AtkImplementorIface, GtkBuildable and GtkActivatable.

Detailed Description

The GtkMenuItem widget and the derived widgets are the only valid childs for menus. Their function is to correctly handle highlighting, alignment, events and submenus. As it derives from GtkBin it can hold any valid child widget, altough only a few are really useful.

GtkMenuItem as GtkBuildable

The GtkMenuItem implementation of the GtkBuildable interface supports adding a submenu by specifying "submenu" as the "type" attribute of a element. A UI definition fragment with submenus

Structures

Convenient Construction

gtkMenuItem is the result of collapsing the constructors of GtkMenuItem (gtkMenuItemNew, gtkMenuItemNewWithLabel, gtkMenuItemNewWithMnemonic) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.

Signals

activate(menuitem, user.data)
Emitted when the item is activated.
menuitem
the object which received the signal.
user.data
user data set when the signal handler was connected.
activate-item(menuitem, user.data)
Emitted when the item is activated, but also if the menu item has a submenu. For normal applications, the relevant signal is "activate".
menuitem
the object which received the signal.
user.data
user data set when the signal handler was connected.
toggle-size-allocate(menuitem, user.data)
undocumented
menuitem
the object which received the signal.
user.data
user data set when the signal handler was connected.
toggle-size-request(menuitem, user.data)
undocumented
menuitem
the object which received the signal.
user.data
user data set when the signal handler was connected.
