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.
