[vtkusers] vtkinteractorStyleFlight-Confused

[John Biddiscombe]

It depends on how you're using the interactors. If you're capturing mouse 
events in your own code, then passing them to the interactors, problem 
solved (hence I doubt this is the case in your program). If you're using a 
built in event handler (ie managed by the vtk window + interactor), then 
yes, hook into the left/right button press methods.

My own preferred choice would be to subclass InteractorStyleFlight, do 
additional processing in each handler and then pass on to the inherited 
functions.

As the person responsible for the flight mode class, I'll welcome any 
suggestions you have for additional functions. If there's something you 
want added and it doesn't change existing stuff. Post away...
