   3 A wxPaintDC must be constructed if an application wishes to paint on the
   4 client area of a window from within an {\bf OnPaint} event.
   5 This should normally be constructed as a temporary stack object; don't store
   6 a wxPaintDC object.
   7
   8 Using wxPaintDC within OnPaint is important because it automatically
   9 sets the clipping area to the damaged area of the window. Attempts to draw
  10 outside this area do not appear.
  11
  12 To draw on a window from outside {\bf OnPaint}, construct a \helpref{wxClientDC}{wxclientdc} object.
  13
  14 To draw on the whole window including decorations, construct a \helpref{wxWindowDC}{wxwindowdc} object
  15 (Windows only).
