Perhaps you can be a bit more concrete. What do you mean by "say hello"?

You should be able to invoke an event from anywhere as long as the
class is derived from vtkObject. It would probably be easier if you
could show us a minimal, compilable example of what you've tried so
far, and explain exactly where it is not working for you.
