Error about " module object has no attribute 'QStringList' "


O

Dear List,

I have been working on restructured text(rest) documents and found a nice application which makes viewing the rest documents easy. It is a web browser especially suited for Sphinx documents.

When I run the code, I get error which says that :

----------------->-----------------------
Traceback (most recent call last):
File "/usr/local/bin/doc-watch", line 73, in <lambda>
self.wb.urlChanged.connect(lambda: self.url.setCompleter(QtGui.QCompleter(QtCore.QStringList([QtCore.QString(i.url().toString()) for i in self.wb.history().items()]), caseSensitivity = QtCore.Qt.CaseInsensitive)))
AttributeError: 'module' object has no attribute 'QStringList'
--------------------<--------------------

I am running python2.7 on Debian Testing. I appreciate any help to shed any light on this error. The code is following:

Best Regards,
Ozhan Fenerci
