[vtkusers] Subclassing abstract vtk classes in Python

[Reinhold Niesner]

Hello vtk users,

Now that the nightly release allows subclassing of vtk classes in Python 
(which is a very nice feature, thanks), I wondered if there is a a way 
to sublass abstract vtk classes in Python. I tried this with 
vtkPolyDataToPolyDataFilter and got a segmentation fault.

I also tried to subclass a concrete filter class and overwrite its 
Execute method, hoping that on update my Exeute method will be executed, 
but had no success.

Is there a way to achieve this?

Thanks,
Reinhold
