[PyQt] QCheckBox problem

[Doug Hackworth]

 > FoobarApplication is calling the wrong super-class __init__.

Duly noted, thanks for the correction.  I changed it to call 
QtGui.QMainWindow.__init__() instead.  The change produced no visible effect, 
but I assume it's a better initialization to call, so thanks for pointing this out.


> Use the stateChanged(int) signal instead.

That did the trick, thanks!  Question:  Was I wrong to use the toggled() signal 
and should have known to use stateChanged(int) instead?  What's the difference 
between the two?

Thanks again,
Doug
