[vtkusers] actorCollection empty after an AddActor...why?

[Roger Blum]

Hi Giancarlo,

I seem to recall to have had the same problem a while ago.

Have you tried calling the method GetViewProps() which is inherited to
the vtkRenderer from vtkViewport? This function returns a vtkPropCollection.

HTH,
Roger
