wx.AutoBufferedPaintDC

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

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

The difference between wx.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.

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