CLASS DESCRIPTION    [Toc]    [Back]

	  The VkWidgetList class provides a convenient way to maintain and
	  manipulate lists of widgets. Widgets can be added and	removed	from
	  the list, or accessed	by index. The VkWidgetList adds	a
	  destroyCallback to each added	widget to maintain the integrity of
	  the list when	widgets	are destroyed.



   VkWidgetList()    [Toc]    [Back]
	   VkWidgetList(void);


	  Initialize an	empty list.

   ~VkWidgetList()
	   virtual void	~VkWidgetList(void);


	  Destroy the storage used by a	VkWidgetList object. Does not destroy
	  any widgets currently	on the list.
