Hi everybody,

I wonder if you know if it is possible to change the default events of the widgets. I am using the vtkBrokenLineWidget and i would like to remove the translation and change the behaviour of the orientation to change the type of rotation around a center.

if i add an observer over one defined it does not listen at all. The only option is to write over the original file?.

I wonder if someone knows how to deal with it or can recommend me a forum where i can get an answer.

Thank you
