  Hi,

I downloaded PySide 4.1 and replaced my PyQt4 imports with PySide. I 
stumbled upon two problems.

1. I use the following code in PyQt4 for QTreeWidgetItemIterator:

iter = QtGui.QTreeWidgetItemIterator(widget)
while(iter.value()):
     item = iter.value()
     ...
     iter += 1

PySide gives me the following exception:
AttributeError: 'PySide.QtGui.QTreeWidgetItemIterator' object has no 
attribute 'value'

Am I doing it the wrong way or isn't this supported yet?

2. I have a custom widget defined like this:

from PySide import QtGui, QtCore

class ViewportWidget(QtGui.QWidget):
     def __init__(self, parent=None):
         QtGui.QWidget.__init__(self, parent)
         self.setAttribute(QtCore.Qt.WA_NativeWindow, True)
         self.setAttribute(QtCore.Qt.WA_PaintOnScreen, True)

     def paintEngine(self):
         return None

I use QWidet::winId() to get the window handle and initialize directx on 
that window. This works great in PyQt4, but PySide tells me that:

AttributeError: 'ViewportWidget' object has no attribute 'winId'

The docs seem to state that winId() should indeed work:
