If possible, you should always reply to the listserv, so that everybody on
the list receives the response.
You are defining text_changed twice. The first time, you make it a Signal,
but then you overwrite it and make it a method. If you instead have the
following:
text_changed2=QtCore.Signal(list,str)
and
self.emit(QtCore.SIGNAL("text_changed2(list,str)"),names,prefix)
then the signals are emitted properly.
Also, you could try using new-style signals and slots (defined at
http://developer.qt.nokia.com/wiki/Signals_and_Slots_in_PySide). They are
much more Pythonic.
