[vtkusers] InteractorStyleFlight - confused

[Dimitris Agrafiotis]

Dear All

I am a little bit confused with the vtkInteractorStyle stuff.
I want to use the vtkInteractorStyleFlight class but for every event I 
want to do some additional things. To be more precise  whenever a 
OnRightButtonDown event takes place I need to capture the camera 
position and then continue with the standard code contained in the 
class. The question is how do I do that?

Do I have to use the  SetLeftButtonPressMethod and if yes can somebody 
help with the argument stuff?

Or do I have to subclass the  vtkInteractorStyleFlight? Again any help 
would be appreciated.

Or is there another way ?

Please Help!!

Thanks in advance
Dimitris
