Everything is in it, that's how I learned everything I know about Qt. At
least that was a sufficient start to understand the big picture.
Sorry, but I cannot be clearer than them (I even hope you understood
anything
I said coz my explanations never look clear to me ;), and it's on at least
4-5 pages.

Hope this helps,
