The first official Trolltech guide to Qt 3.2 programming!
Straight from Trolltech, this book covers all you need to build industrial-strength applications
with Qt 3.2.x and C++-applications that run natively on Windows, Linux/Unix, Mac OS X, and
embedded Linux with no source code changes! The book teaches solid Qt programming
practices; it is not a rehash of the documentation. You'll find start-to-finish coverage packed
with examples, plus a CD with the Qt 3.2 toolset and Borland C++ compilers-including a non-
commercial Qt 3.2 for Windows available nowhere else!
Build powerful C++ GUI applications quickly and easily
Design dialogs and main windows visually and in code
Learn Qt's innovative typesafe signals and slots mechanism
Use layouts to create forms that automatically size and scale
Create custom signals, slots, events, and controls
Program the ''Qt way'' with techniques for Qt 3.2 that'll work with Qt 4

Already using Qt or just starting out? Evaluating Qt or managing it? Building open source
applications-or commercial applications? Want to develop for Windows without buying an
expensive compiler? Whatever your goal, this is the only book you need! CD-ROM: Everything
you need to write great GUI programs!

Foreword
Why Qt? Why do programmers like us choose Qt? Sure, there are the obvious answers: Qt's
single-source compatibility, its feature richness, its C++ performance, the availability of the
source code, its documentation, the high-quality technical support, and all the other items
mentioned in Trolltech's glossy marketing materials. This is all very well, but it misses the most
important point: Qt is successful because programmers like it.
How come programmers like one technology, but dislike another? Personally, I believe software
engineers enjoy technology that feels right, but dislike everything that doesn't. How else can

"...not only the best book on Qt I have ever seen, but also the best book presenting any
programming framework. Every sentence appears to be carefully worded, and every chapter
has a sound concept, and so does the work as a whole."
-Matthias Ettrich, Trolltech's lead developer, founder of the KDE project
"The 'Tao of Qt'.... The Qt system is a beautiful example of object oriented design, and the
authors take advantage of this.... The authors have done an excellent job of presenting the
subject in an interesting and engaging way...."
-Ron McCarty, Instructor and Chair of the Department of Computer Science, Penn State Erie,
The Behrend College
The first official Trolltech guide to Qt 3.2 programming!
Straight from Trolltech, this book covers all you need to build industrial-strength applications
with Qt 3.2.x and C++-applications that run natively on Windows, Linux/Unix, Mac OS X, and
embedded Linux with no source code changes! The book teaches solid Qt programming
practices; it is not a rehash of the documentation. You'll find start-to-finish coverage packed
with examples, plus a CD with the Qt 3.2 toolset and Borland C++ compilers-including a non-
commercial Qt 3.2 for Windows available nowhere else!
Build powerful C++ GUI applications quickly and easily
Design dialogs and main windows visually and in code
Learn Qt's innovative typesafe signals and slots mechanism
Use layouts to create forms that automatically size and scale
Create custom signals, slots, events, and controls
Program the ''Qt way'' with techniques for Qt 3.2 that'll work with Qt 4
