still confused with QTsignal

[root]

I'm now more confused than ever with PYSIGNALS, 
in the following class:


class mixer:
    
     def __init__(self, parent=None):
         self.ms=mixer_sub(None,parent)
         QObject.connect(self.ms,PYSIGNAL("rec_button_clicked"),self.print)
         QObject.connect(self.ms,PYSIGNAL("rec_button_clicked"),self.ms.print)

      def print(self):
          print "Recieved signal"  

the print function never gets called even though the print function in the 
self.ms object does. I have tried leaving off the 'self' in the 3rd param, 
making mixer inherit QObject and lots of variations on the syntax. As far as I 
can see this should work but doesn't.
