CLASS DESCRIPTION    [Toc]    [Back]

     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.
