[wxPython-users] How to use custom control in XRC?

[甜瓜]

I want to use wx.BitmapFromBuffer control in a wxFrame, but xrced does
not provide this control button. It has a icon "Unknown control" which
may be the way. Could you give me some examples for dealing with
custon control in xrc? Or, simply create the custom control in python
code rathar than xrc file. I need some clue.

Thank you.
