[vtkusers] QVTKWidget2 and wheel Event

[Doug Hoppes]

Thanks... I'll take a look at the QVTKInteractorAdapter.  I'm just surprised that I can't just do pass-through of the event.  I'm assuming that this will be true with the mouse-click events.  For those events, I was going to check to make sure that I didn't have a QGraphicsItem under my mouse and, if there wasn't any, send the message to the VTK window.

Oh, I see you were trying to pass it but couldn't call QVTKWidget2::wheelEvent().

How about just making your own QVTKInteractorAdapter and call ProcessEvent()?
