<![CDATA[Change response of render window to interactions]]>I am using a Qvtkwidget to display images in an application. Image interactions are enabled via render window interactor. vtkinteractorstyle image is used. Clicking and dragging on the image results in window and level change. However the scale of this change is drastic. Is there any way to reduce the range of this change? Or rather change the response of click and drag to say, panning the image.

Pressing down shift button + click and drag OR
Mouse wheel down and drag, results in panning the image.
Could it be manipulated so that simple click and drag pans the image.

Was hoping to get some insight in that direction. Thank you for the response :)

That is something you should ask to the VTK folks.
