Qt Assistant is a tool for viewing on-line documentation in Qt help file format.
Qt Assistant works in a similar way to a Web browser. If you click hyperlinks (cross-references), the Documentation window will present the relevant page. You can bookmark pages of particular interest and you can click the Previous and Next toolbar buttons to navigate within the pages you have visited.
Although Qt Assistant can be used just like a Web browser to navigate through the documentation, Qt Assistant offers a powerful means of navigation that Web browsers do not provide. Qt Assistant uses an advanced full text search engine to index all the pages in each compressed help file so that you can search for particular words and phrases.
This is free and open source software.
