[vtkusers] Problem using vtkDistanceWidget

[Jafari, Kourosh]

Dear all,
I’m using vtkDistanceWidget to interactively measure distance between two points in a 2D image displayed using vtkImageReslice for a 3D volume. It works fine but the problem is that I have assigned a scrollbar to this window and when I click on it the window shows a different slice, but the distance widget stays still. It does not disappear when I go to a different slice. Any idea how to fix this problem?
Thanks a lot!
