I tried this trick later and found that it didn't do what I expected with
the widgets created by the setupUi() method. These are created as attributes
of the ui object and not the widget they are applied to.

I just thought I'd mention this in case someone was trying to use this
technique and found that they couldn't reference the widgets in their user
interface.
