[vtkusers] using GetWindow, GetLevel methods of vtkImagePlaneWidget with Tcl

[Dean Inglis]

Hi David,
 
This worked for me.
 
planeWidget AddObserver WindowLevelEvent wlobserve
vtkTextActor textActor
ren AddActor2D textActor
vtkRenderWindowInteractor iren
 

proc wlobserve { } {

  set str [ planeWidget GetWindow ]

  textActor SetInput $str

  textActor Modified

  iren Render

}
