Thanks Rakesh, thanks for commenting this out. 

I was thinking on using a similar solution to my problem, but I just
can't find the way to trigger the Mouse Click event on a
vtkDistanceWidget or vtkAngleWidget.

I tried adding observers with myDistanceWidget->AddObserver(...) but the
event wasn't fired. I also used
myDistanceWidget->GetInteractos()->AddObserver(...), in this case the
event is fired, but not for my widget, but for the whole interactor.

Could you show me the code to handle the mouse click event on the
widget?.
