The example should have read: "super(MyWidget,
self).__init__(parent)", not "super(Qt.QWidget,
self).__init__(parent)". In this example, there is no difference
between the two syntaxes, but in cases involving multiple inheritance,
super() returns a proxy that delegates calls to the appropriate
superclass, as determined by the method resolution order. More here:
