[PySide] The __iadd__ method is missing in QTextFrame.iterator

[Bjørn Helge Kjøsnes]

Hi,

I have been trying to extract information from a QTextEdit object using 
code, but run in to problems iterating the elements inside a 
QTextDocument. It seams like there is no way to get to the next element 
after starting iterating using the rootFrame.begin() method. If you 
examine the metgod list using dir(titer), you will find that it is 
missing the __iadd__ and __isub__ methods in PySide. It is missing in 
the documentation as well.

http://www.pyside.org/docs/pyside/PySide/QtGui/QTextFrame.iterator.html 
is missing __iadd__ and __isub__
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qtextframe-iterator.html 
is having both a __iadd__ and an __isub__

I have attached a example that works fine in PyQt4 but not in PySide.

Here is the method not working:
    def rebuildtree(self):
        self.rtree.clear()
        tdoc = self.redit.document()
        rframe = tdoc.rootFrame()
        titer = rframe.begin()
        while not titer.atEnd():
            tb = titer.currentBlock()
            if tb:
                treeitem = QtGui.QTreeWidgetItem(self.rtree)
                scontent = 'a text block (%s)' % tb.text()
                treeitem.setText(0, scontent)
            else:
                tf = titer.currentFrame()
                treeitem = QtGui.QTreeWidgetItem(self.rtree)
                treeitem.setText(0, 'a frame')
            res = dir(titer) # This one is missing the __iadd__ in PySide
            titer.__iadd__(1) #This can be used in PyQt4 but not found 
in PySide


Is this a bug or have I missed out on another smarter way of getting the 
next element using the iterator.

Thanks,
