[vtkusers] vtkInteractorStyleUser in Python

[Roman Putanowicz]

Hi, 

I remember I have read that virtual methods do not propagate
into Python. The question is then:

How can one use vtkInteractorStyleUser in Python? 
The problem is that since VTK 4.2 the method  SetKeyPressMethod
is obsoleted, but as I understand the substitute for it, OnKeyPress,
is a virtual one. 

All examples I was able to find uses SetKeyPressMethod.

I would appreciate any hints.
