[vtkusers] Qt Events and vtkObserver

[Ale]

Moreover I wonder how, in this case of slots usage instead of Interactor, how can I share the same interactor among several QVTKWidgets?

Instead, i found out how to stop the propagation using  AbortFlagOn but it seems to working in a "delayed" mode. If, as instance, I set a new slice, the display update the image only (resetting the camera) but no annotation is changed.

I did also tried to attach a vtkObserver but it seems not to work. Should I instantiate a InteractorStyle? Where did I have to attach it?
