[PyQt] PyQt's Undo/Redo framework - A Very Short Intro

[Mark Summerfield]

Hi,

I've written a very short introductory article on using PyQt's Undo/Redo
framework. It is available here:

http://www.informit.com/articles/article.aspx?p=1187104

(The indentation of the last line of the delete() method is wrong---I've
told InformIT so they may have fixed it by now, but if not you'll spot
it anyway.)

The article has been heavily edited for style so it doesn't read like my
usual writing, but the content is fine:-)
