Thank you for replying :)

I hear what you are saying and on designer QT3 this works very well.

Unfortunately I did not explain myself very well. I am using designer QT4 
which has done away with the option of creating slots inside the generated 
dialogue ... thus my problem !

Execution of ...
print justify_dialog.exec_()
continues indefinitely, 

I was hoping that 
QtCore.QObject.connect(justify_dialog.pushButton_3,QtCore.SIGNAL("clicked()"),justify_dialog,QtCore.SLOT("done(2)"))
would call widget.done(2) which exits the dialog and justify_dialog.exec_() 
returning a 2. Although since it does not work I am more than happy to stand 
corrected.
