AttributeError: 'module' object has no attribute 'QtString'

I chaged code:

The issue is explained here http://inputvalidation.blogspot.com/2010/10/python3-pyqt4-and-missing-qstring.html

The reason why you couldn't load QString is that it is missing from PyQt4 (maybe earlier, who knows). Since Py3k, as opposed to Py2k, supports Unicode by default, there's no need in this class.

Instead of QString, for compatibility reasons, you should use this snippet somewhere around your import's:

try:
    from PyQt4.QtCore import QString
except ImportError:
    QString = str

Do you mean QString instead of QtString ?

(you can do help(QtCore) in the python interpreter and search for string)
