[vtkusers] Which mouse button in vtkImagePlaneWidget?

[Ralph Brecheisen]

Hi,

I have a vtkImagePlaneWidget that I also use to move around clipping
planes. I'm catching its vtkCommand::InteractionEvent but I only want to
update the clipping planes if I'm actually moving the slices (which I
assigned to the left mouse button), not when I'm adjusting window level
(which I assigned to the right mouse button). Is there a way to find out
which mouse button I'm pressing? Someone asked a similar question
in vtkusers but there was no reply (
http://www.vtk.org/pipermail/vtkusers/2009-July/101727.html).

Thanks,

Ralph
