<p>We assume that you already know C++.</p>

<p>The best way to learn Qt is to read the official Qt book, <a href="http://www.amazon.com/exec/obidos/ASIN/0131240722/trolltech/">C++ GUI Programming with Qt 3</a> (ISBN 0-13-124072-2). This book is also available <a href="http://phptr.com/content/images/0131240722/downloads/blanchette_book.pdf">online (PDF, 21.8 MB)</a>. This book provides comprehensive coverage of Qt programming all the way from "Hello Qt" to advanced features like multithreading, 2D and 3D graphics, networking, and XML. The book covers Qt 3; a Qt 4 version of the book is in the works. See <a href="http://www.trolltech.com/developer/books.html">Qt Programming Books</a> for a complete list of Qt books, including translations.</p>

<p>If you want to program purely in C++, designing your interfaces in code without the aid of any design tools, read the <a href="tutorial.html">tutorial</a>. The tutorial is designed to get you into Qt programming, with the emphasis on working code rather than being a tour of features.</p>

<p>If you want to design your user interfaces using a design tool, then read at least the first few chapters of the <a href="designer-manual.html">Qt Designer manual</a>.</p>

<p>By now you'll have produced some small working applications and have a broad feel for Qt programming. You could start work on your own projects straight away, but we recommend reading a couple of key overviews to deepen your understanding of Qt: the <a href="object.html">Qt Object Model</a> and <a href="signalsandslots.html">Signals and Slots</a>.</p>

<p>At this point, we recommend looking at the <a href="overviews.html">overviews</a> and reading those that are relevant to your projects. You may also find it useful to browse the source code of the <a href="examples.html">examples</a> that have things in common with your projects. You can also read Qt's source code since this is supplied.</p>

<p>If you run the <tt>qtdemo</tt> application, you'll see many of Qt's widgets in action.</p>

<p>Qt comes with extensive documentation, with hypertext cross-references throughout, so you can easily click your way to whatever interests you. The part of the documentation that you'll probably use the most is the <a href="index.html">API Reference</a>. Each link provides a different way of navigating the API Reference; try them all to see which work best for you. You might also like to try <a href="assistant-manual.html">Qt Assistant</a>: this tool is supplied with Qt and provides access to the entire Qt API, and it provides a full text search facility. There are also a growing number of <a href="http://www.trolltech.com/developer/books.html">Qt books</a>.</p>
