NAME

       wxPaintEvent - Functions for wxPaintEvent class

DESCRIPTION

       A paint event is sent when a window's contents needs to be repainted.

       The  handler  of  this  event  must  create a wxPaintDC object and use it for painting the
       window contents. For example:

       Notice that you must not create other kinds of wxDC (e.g.  wxClientDC  or  wxWindowDC)  in
       EVT_PAINT handlers and also don't create wxPaintDC outside of this event handlers.

       You  can  optimize  painting  by retrieving the rectangles that have been damaged and only
       repainting these. The rectangles are in terms of the client area, and are  unscrolled,  so
       you  will  need to do some calculations using the current view position to obtain logical,
       scrolled units. Here is an example of using the wxRegionIterator (not implemented  in  wx)
       class:

       Remark: Please notice that in general it is impossible to change the drawing of a standard
       control (such as wxButton) and so you shouldn't attempt to handle paint events for them as
       even  if  it  might work on some platforms, this is inherently not portable and won't work
       everywhere.

       This class is derived (and can use functions) from: wxEvent
