|phoenix_title|  **AutoBufferedPaintDC**
==========================================================================================================================================

This :ref:`DC`  derivative can be used inside of an  ``EVT_PAINT()``   event handler to achieve double-buffered drawing.           

Just use this class instead of :ref:`PaintDC`  and make sure :meth:`Window.SetBackgroundStyle`   is called with ``BG_STYLE_PAINT`` somewhere in the class initialization code, and that's all you have to do to (mostly) avoid flicker. 

The difference between :ref:`BufferedPaintDC`  and this class is that this class won't double-buffer on platforms which have native double-buffering already, avoiding any unnecessary buffering to avoid flicker. 

:ref:`AutoBufferedPaintDC`  is simply a typedef of :ref:`PaintDC`  on platforms that have native double-buffering, otherwise, it is a typedef of :ref:`BufferedPaintDC`.
