[vtkusers] QVTKInteractor problem

[Clinton Stimpson]

So which callbacks aren't working?  I don't see how trying to make 
another event loop would solve a callback problem.
If its a dialog, why not call exec() on it instead of show() ?  exec() 
will create a temporary local event loop (see QEventLoop).
Also, each thread can only have one event loop active at a time, and all 
Qt widgets are on the same thread.
