[vtkusers] How to turn off the dragable function of vtkDistanceWidget ?

[Yihui Cao]

Dear all,


After set a vtkDistanceWidget on an image, the widget set can be changed by dragging a handle. I want to turn off the drag function that makes the DistanceWidget is fixed.


So, how to turn off the vtkDistanceWidget dragable function?


I tried to set the corresponding vtkDistanceRepresentation2D PickableOff() and DragableOff(). But it did not work.


Thanks!
