bugtracker, so far no answer. The problem seems not the class vtkAngleWidget
itself, its rather related to a different behavior of one of it’s
superclasses, I guess it is vtkAbstractWidget. So in the end vtkAngleWidget
needs to be changed to accommodate this new behavior.<o:p></o:p></span></font></p>
