* basic idea is this. create classes which wrap the PreferencesWidgets.
* Each should have it's own get(), set() and widget() methods. those are the
* functions that we really care about.
* get() and set() allow for introspection and manipulation of the underlying
* objects. they also handle pinging the plugin which owns the PreferencesWidget,
* i.e. calling PreferencesWidget::callback().
* widget() builds the actual Qt side of the widget, hooks up the relevant signals
* to slots, etc. the result of widget() is not const as it is linked into a
* layout manager or shown or whatever.
