It's not ideal, but you could create your own iterator class to help with
this task:

  class Iter(QTreeWidgetItemIterator):
      def __init__(self, *args):
          QTreeWidgetItemIterator.__init__(self, *args)
      def next(self):
          self.__iadd__(1)
          value = self.value()
          if value:
              return self.value()
          else:
              raise StopIteration

It looks like QTreeWidget could provide an __iter__() method to allow
an improved iterator to be used for constructs such as for loops. That
would also be useful.
