Now, two Trolltech insiders have written a start-to-finish guide to getting outstanding results with the latest version of Qt: Qt 4.3. Packed with realistic examples and in-depth advice, this is the book Trolltech uses to teach Qt to its own new hires. Extensively revised and expanded, it reveals today's best Qt programming patterns for everything from implementing model/view architecture to using Qt 4.3's improved graphics support. You'll find proven solutions for virtually every GUI development task, as well as sophisticated techniques for providing database access, integrating XML, using subclassing, composition, and more. Whether you're new to Qt or upgrading from an older version, this book can help you accomplish everything that Qt 4.3 makes possible. • Completely updated throughout, with significant new coverage of databases, XML, and Qtopia embedded programming • Covers all Qt 4.2/4.3 changes, including Windows Vista support, native CSS support for widget styling, and SVG file generation • Contains separate 2D and 3D chapters, coverage of Qt 4.3's new graphics view classes, and an introduction to QPainter's OpenGL back-end • Includes new chapters on look-and-feel customization and application scripting • Illustrates Qt 4's model/view architecture, plugin support, layout management, event processing, container classes, and much more • Presents advanced techniques covered in no other bookâ€from creating plugins to interfacing with native APIs • Includes a new appendix on Qt Jambi, the new Java version of Qt 1 C++ GUI Programming with Qt 4, Second Edition by Jasmin Blanchette; Mark Summerfield Publisher: Prentice Hall Pub Date: February 04, 2008 Print ISBN-10: 0-13-235416-0 Print ISBN-13: 978-0-13-235416-5 eText ISBN-10: 0-13-714397-4 eText ISBN-13: 978-0-13-714397-9 Pages: 752 Table of Contents | Index Copyright Series Editor's Note Foreword Preface Acknowledgments A Brief History of Qt Part I: Basic Qt Chapter 1.

First printing, February 2008 5 Series Editor's Note Dear Reader, As a working programmer, I use Qt every day, and I am really impressed by the organization, design, and power that Qt brings to the C++ programmer. While Qt began life as a cross-platform GUI toolkit, it has expanded to include portable facilities for just about every aspect of day-to-day programming: files, processes, networking, and database access, to name just a few. Because of Qt's broad applicability, you really can write your code once and just recompile it on a different platform in order to have it work out of the box. This is extraordinarily valuable when your customer base requires your product to run on different platforms. Of course, because Qt is also available with an open source license, if you're an open source developer, you too can benefit from everything Qt has to offer. While Qt comes with extensive
