[vtkusers] Qt Events and vtkObserver

[Ale]

You're right. I'd like to "re-program" the whole behavior to adapt it to different styles... I tried the vtkObserver added to the Render Window but it seems not to be fired... 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?
