In case anyone else stumbles upon the need to do word wrapping 
themselves for a QTextDocument, I've gone ahead and implemented my own 
somewhat-generic routines in a project I'm working on, hosted at google 
code:

Project 'dviz', Line 609 (r25) of /trunk/src/items/TextboxContent.cpp 
begins the layout routine. It stores the text as a list of strings with 
associated format and position on screen.  See the following link on 
google code to jump right to that file/line:

Anyone with ideas for improvement - please let me know. I am by no means 
a typography expert, text layout specialist, or anything of the like - I 
just have a need for custom painting a QTextDocument, while retaining 
word wrapping, so this is really just scratching my own itch. If it 
helps others, all the better!

Interested in any feedback you may have.

Cheers!
