[vtkusers] InfoVis: vtkGraphLayoutView in QVTK Widget

[Clinton Stimpson]

They PyQt4 wrapping doesn't have a SetRenderWindow().  Did you make your 
own?
The PyQt[4] code isn't a wrapper around the C++ QVTKWidget class.

And Jeff, what changes and where were you thinking of to remove the 
SetInteractor()?
I imagine vtkXRenderWindowInteractor needs changed.
