Alex,

I don't think I follow. If I call vtkSphereWidget::ProcessEvents from
MySphereWidget::ProcessEvents, that doesn't seem like it will allow me
to handle the events any differently in MySphereWidget::ProcessEvents?
I tried what yo suggested anyway, and it still does not output
"InteractionEvent" or "StartInteractionEvent". Would you take a look
at the updated version?
