You need to subclass an InteractorStyle

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents

and reimplement the functions like OnRightButtonDown(), etc. to call
the ones that you want to switch the behavior. For example:

    virtual void OnRightButtonDown()
    {
      vtkInteractorStyleTrackballCamera::OnLeftButtonDown();
    }

to make the behavior that normally happens when you click the left
button now happen when you click the right button. (Make sure you also
switch the *Up() functions as well, or you will get unexpected
behavior).

Good luck,

David
