Like I said, the slot must be a member of a QObject derived class. Also,
sender() should be from the receiver - there's no point in asking the
sender who the sender is :)

So, testDlg should sub-class from QObject and the lostFocus() method
should be...

    def lostFocus(self):
        print self.sender()
