[vtkusers] Disable vtkGenericWindowInteractor?

[Stephan Theisen]

Hi together!

I've the following problem: I've developed a vtkCanvas and implemented a 
vtkGenericWindowInteractor. But
this Interactor does too much. Because if I want to interact with an 
other panel, that is active for the moment and
overlays the vtkCanvas, the Interactor for the vtkCanvas reacted. How 
can I disable the interactor of the vtkCanvas
during I interact with other panels?

Thanks in advance

Stephan
