commit abc9b00c6470f9f6b66c280455f544ad0ee3aa8c
Author: Pino Toscano <pino at kde.org>
Date: Sat Feb 16 16:09:52 2008 +0100
Basic work in the demo PDF viewer, open documents and navigate into the pages.
An observer structure was introduced, so extra components can be easily added and made aware of the document/page changes.
Both the navigation toolbar and the page view are implemented as observers.
