[vtkusers] VTK Contour Widget Problem

[Gishara Indeewarie]

Hi all,
When I comment the line  " interactor->SetInteractorStyle(style)" the
contour lines is displayed, but not in the right position.
I have to rotate and make it on the right place.
Can you please tell me how could I make it appear on the right position?
Thanks.
