PyQwt has a partial interface to the following dictionary iterators:
The iterators cannot be instantianated from Python, but are returned by a few methods. They are not equivalent to Python iterators. An usage example is:
>>> plot = qplt.testPlot() >>> iterator = plot.curveIterator() >>> curve = iterator.next() >>> while curve: ... print curve ... curve = iterator.next() ... <Qwt4.Qwt.QwtPlotCurve object at 0xb28c8a2c> <Qwt4.Qwt.QwtPlotCurve object at 0xb28c8e2c> <Qwt4.Qwt.QwtPlotCurve object at 0xb28c8a2c> <Qwt4.Qwt.QwtPlotCurve object at 0xb28c8e2c> >>>

True if the dictionary is empty, i.e. count() == 0;
otherwise returns False.

If the dictionary is empty it sets the current item to None and
returns None.

If the current iterator item was the last item in the dictionary or if it
was None, None is returned.
