Thats great. Now I finally understand how it works. Thanks!

#2 Glenn commented on 2010-04-08:

But this fragment doesn't work with the latest stuff:

File "D:mypytest7.py", line 42, in data return QVariant() TypeError: PyQt4.QtCore.QVariant represents a mapped type and cannot be instantiated

#3 Nader commented on 2011-08-22:

Add this to the top of the file to make it run using PyQt version 4.7.3

import sip sip.setapi('QVariant', 1)

from PyQt4.QtCore import from PyQt4.QtGui import import sys
