[vtkusers] vtkinteractorstyleuser/observer callback

[H A]

Hello everyone,
                I am using vtk 4.0 and VC++, I am trying to assign functions 
to different events.  For instance, if you left click on your mouse an 
object gets translated.  I have been able to output messages to cerr but 
everytime I try and do something to the actors I get a sharing violation 
error.  I have subclassed vtkinteractorstyleuser to do this.  I have not 
been able to find an example anywhere of how to do this.  Can anyone pls 
provide me with a C++ example?  Either using vtkinteractorstyleuser or the 
observer callback method.  I just want to be able to custom interact with my 
software :)

Thank you,

H.A.
