It's not that you're all wrong as that what you're describing is a
special form of object protocol that primarily applies in GUI design.
You can certainly perform this kind of operation in Python, but unless
you're using a framework, it's not automatic.  Before I (or other
people) give you specific advice about the best way to implement this,
it'd be good if you gave us more information about what you're trying to
accomplish.
