From the Author
All the book's examples can be downloaded from the book's web page. (Amazon don't allow URLs so google for "qtrac" to find the page.) Note also that versions of the examples are also available for Python 3.1 and the PyQt's API 2--the book uses Python 2 and API 1, but the differences aren't that great as explained at the bottom of the book's web page.
