[wxPython-users] transparent background for a panel widget

[Christopher Barker]

This is going to be tricky.

One thing to keep in mind is that DCs don't really support transparency, 
so when you do:

DC.SetBrush(wx.TRANSPARENT_BRUSH)

then draw, you're not drawing transparent pixels -- you're drawing 
nothing, so whatever was there before the drawing call is still there -- 
and it's probably not transparent -- it's black, or whatever junk is 
left in memory.

I wish I could tell you how to do what you want....

Have you tried just plain:

def OnPaint(self, evt):
     dc.wx.PaintDC(self)
     evt.Skip()
