You should be able to SafeDownCast the vtkObject in the callback to
determine which object the event was triggered from:

 void Viewer::mouseMoveCallback(vtkObject * obj, unsigned long, void *
client_data, void *,  vtkCommand * command)
{
  vtkMyInteractorStyle* callingInteractorStyle =
vtkMyInteractorStyle::SafeDownCast(obj); // Replace
vtkMyInteractorStyle with the type of the object that is producing the
event
}
