Access Functions

virtual VkMenuItemType menuType();
Boolean hasUndo()CLASS DESCRIPTION
The VkMenuAction class represents a user-selectable command in a menu.
Objects of type VkMenuAction can be placed in any VkMenu subclass. The
VkMenuAction adds an XmPushButton widget into its parent menu pane. Like
all VkMenuItems, VkMenuAction objects can be activated, deactivated,
replaced, and so on.
If an action has an undo callback, the object automatically registers
itself with an instance of the VkUndoManager class when the action is
executed. An undo callback can be specified when the object is
instantiated.
