[vtkusers] [VTK + Python] vtkProcess - vtkCommand - start/update/end events

[Andy Cedilnik]

Hi Benoit,

You should use observers. Look at the answer from couple of days ago:

------------------------------------------------------
oid = o.AddObserver('InteractionEvent', move)

...blah blah...

o.RemoveObserver(oid)

JDH
------------------------------------------------------

Replace InteractionEvent with whatever event you need.
