BufferedPaintDC
This is a subclass of wx.BufferedDC which can be used inside of an
EVT_PAINT event handler. Just create an object of this class instead
of wx.PaintDC and that's all you have to do to (mostly) avoid
flicker. The only thing to watch out for is that if you are using this
class together with wx.ScrolledWindow, you probably do not want
to call wx.Window.PrepareDC on it as it already does this internally
for the real underlying wx.PaintDC.
If your window is already fully buffered in a wx.Bitmap then your
EVT_PAINT handler can be as simple as just creating a
wx.BufferedPaintDC as it will Blit the buffer to the window
automatically when it is destroyed. For example:
def OnPaint(self, event):
dc = wx.BufferedPaintDC(self, self.buffer)

(Constructor)
Create a buffered paint DC. As with wx.BufferedDC, you may either
provide the bitmap to be used for buffering or let this object create
one internally (in the latter case, the size of the client part of the
window is automatically used).
