    @class wxPaintDC
    @wxheader{dcclient.h}

    A wxPaintDC must be constructed if an application wishes to paint on the
    client area of a window from within an @b OnPaint event.
    This should normally be constructed as a temporary stack object; don't store
    a wxPaintDC object. If you have an OnPaint handler, you @e must create a
    wxPaintDC
    object within it even if you don't actually use it.

    Using wxPaintDC within OnPaint is important because it automatically
    sets the clipping area to the damaged area of the window. Attempts to draw
    outside this area do not appear.

    To draw on a window from outside @b OnPaint, construct a wxClientDC object.

    To draw on the whole window including decorations, construct a wxWindowDC object
    (Windows only).
