Qt Qurl

['holic]

Hi guys,
I'm trying to write a small app in Qt in which I want to
- set the username and password on a web page
- download data from a page
- examine links that appear on a page and navigate to them
- fill in a form and get a response

The Qurl class appears to be what I need, I've read the API but it's a bit of a mystery to me. Can anyone recommend any good links/books which can give me a basic understanding of what's required to use Qurl.

Thanks
