[PyQt] Signals and slots from promoted widgets in Qt Designer

[todd rme]

I am trying to use Qt designer to create a GUI using custom PyQt4
widgets.  I know how to promote widgets, but when I do I do not see
any of the custom signals or slots in the promoted widget.  Is there a
way to promote a PyQt widget in designer so that I can use the signals
and slots inside designer?
