Yes, your __init__() will override the base class __init__(). To include 
the base class functionality, just call the base class __init__() from 
your __init__(). The syntax for this is a little different from the 
usual method call; in your __init__() include this call:
   wxVTKRenderWindow.__init__(self, args)

where args is whatever argument list you want to pass to the base class 
__init__().
