Hard to say with some code to experiment with. You might try:
 - try:
       widget.readOnly(True)
   except AttributeError:
       pass
   before widget.setEnabled(False)
 - use a two pass approach, where the loop with the
   widget.setEnabled(False) body is called from a QTimer.SingleShot(0, )
 - a mixture of these
