[vtkusers] vtkImageViewer2 and current Mouse Position (MouseMove)

[Margarete Herbst]

Hello,

I would like to get the current hovered mouse position in a vtkImageViewer2.
I added an observer for vtkCommand::MouseMoveEvent to the
vtkImageViewer2-instance's interactor style. Now I can retrieve the current
mouse-position using a vtkPointPicker connected to
vtkImageViewer2-instance's ImageActor.
The problem: interactive windowing/leveling, zooming ... (except zooming via
mouse wheel) isn't possible anymore. I guess my 'interfering'
MouseMoveEvent-observer is the problem. But how could I overcome that?!
Could someone help me, please?

regards,
marge
