VkCursorList(3x)

NAME
     VkCursorList - Support lists of cursors that can be used for animation

HEADER FILE
     #include <Vk/VkCursorList.h>

PUBLIC PROTOCOL SUMMARY
   Destructor
           virtual void ~VkCursorList(void);


CLASS DESCRIPTION
          This abstract base class manages a list of cursors and supports
          functions for cycling through the list. It is used as the basis of
          VkBusyCursor, which provides a sequence of animated busy cursors. To
          add alternate busy cursors to a ViewKit application, one can
          subclass VkCursorList, provide the desired sequence of Cursors, and
          install the new class with the VkApp object.



PUBLIC METHOD DESCRIPTIONS
   ~VkCursorList()
           virtual void ~VkCursorList(void);


          Frees the storage associated with a VkCursorList object.

   next()
          Cursor next();


          Returns the next Cursor in the sequence.

   current()
          Cursor current();


          Returns the current cursor in the sequence.

   reset()
          void reset();


          Resets a sequence of Cursors to the initial Cursor in the animation
          sequence.
DERIVING SUBCLASSES
          To use the VkCursorList class, you must create a subclass. The
          subclass must implement the createCursor() method, which is expected
          to return a Cursor, given an index into a sequence.

PROTECTED METHOD DESCRIPTIONS
   VkCursorList()
           VkCursorList(int numCursors);


          Initializes a VkCursorList object. This constructor must be called
          from a derived class constructor. The numCursors argument must
          indicate the number of Cursors in the sequence of animated Cursors
          this class will create.

   createCursor()
              virtual void createCursor(int index) = 0;


          VkCursorList uses a lazy evaluation method for creating Cursors. No
          Cursors are created initially. VkCursorList maintains a list of
          cursors that is supplied to clients via calls to next() and
          current(). When VkCursorList needs a Cursor that has not yet been
          created, it calls createCursor() with an index that indicates the
          needed Cursor. Subclasses are expected to implement this function
          and be able to return the appropriate Cursor.
