Anything that is intended to be used as a notebook plugin is
supposed to derive from

        client/wxpython/gmPlugin.py::cNotebookPlugin

That class makes sure (among other things) that

- on load plugins are registered with the menu system

- provides a default can_receive_focus() method
        - many plugins use that to check whether there is an active patient

- provides a default receive_focus() method
        - calls self._widget.repopulate_ui() if that exists

The methods can_receive_focus() and - if so -
receive_focus() are called on the plugin by the notebook
when that plugin is activated.

So, in effect, you'd want to override .repopulate_ui() in
your widget and do whatever is needed there.
