[pygtk] AttributeError: 'module' object has no attribute 'GtkWindow'

[Kyle Robson]

I posted yesterday about an error getting installing pygtk 2.16 on
Windows 7. To get working despite this, I installed Ubuntu 9.10, which
comes with pygtk. I still get the same error, though, running the tree
example! The example I'm trying to run is:
http://www.pygtk.org/pygtktutorial/sec-treeexample.html

The error I get is: AttributeError: 'module' object has no attribute 'GtkWindow'

Is GtkWindow depreciated, or is my pygtk not up to date? I would
greatly appreciate any help.

Thanks,

Kyle
