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.
