CGXCellTipWnd is a base class implementation for cell tip windows. You should derive your own cell tip window objects from this base class. All necessary message forwarding is implemented in this class. In your derived class, you only need to override CreateTipWnd to perform any special initialization and OnPaint to perform your cell tip window's specific drawing code.
