Although my "Rapid GUI Programming with Python and Qt" is Python

One simple "cheat" is to create a QGraphicsItem that is the same size as

Overall I was pleasantly surprised at how straightforward the porting
was (although I didn't do much testing!). API 2 code is cleaner and
clearer than API 1 code---and more Pythonic with the use of str instead
of QString and the elimination of QVariant.

Since Python 2.6 isn't officially available yet I've tested against
release candidate 2 and the PyQt 4.4.4 snapshot and used the -3 flag.
I hope that this is useful to those who want to make the move to 2.6!

In Python 3 you'll be able to do "import builtins" and use
