I don't know anything about designer plugins, so this is more from the
general Python perspective:
This certainly works - I sometimes use it for small helper functions.
It seems like it works fine with classes as well.
However, IMHO it would be cleaner to just define multiple classes in a
module, all on the toplevel, like this:
(Definition of myCustomCombo goes here)
(Definition of mypopupdialog goes here, including some
(Definition of mylineedit goes here including key event handler
that execs a mypopupdialog)
