If I got a pointer to vtkDistanceRepresentation2D (through a picker), how can I get a pointer to my vtkDistanceWidget which contain this vtkDistanceRepresentation2D ?
I mean, if I find a pointer to vtkDistanceRepresentation2D (vtkProp), how can I find its associated parent widget (vtkDistanceWidget) ? I have read their source code, but vtkDistanceRepresentation2D (and its parents) have no pointer to its widget … or, I didn’t saw it …
