The Book of Qt 4: The Art of Building Qt Applications ReviewThis book is a fairly standard tutorial on building user interfaces. It covers the basics, and should be sufficient to get most C++ programmers up to speed. However, there are quite a few points in the book where the author hand-waves his way through a process. This can make following the tutorials somewhat confusing and gets in the way of the general understanding of the process. In addition, either because of platform differences or poor testing, some of the examples do not work properly. For example, in the cuteedit2 example in Chapter 4, the buttons for the discard changes dialog have their meaning reversed. On the surface it is hard to tell if this is a bug in the book or in the OS X implementation of QT 4. Finally, many key ideas a mentioned almost in passing (like the use of the tr() function to aid in translations), making it imperative to carefully read every word.
This text pales in comparison to the Hillegass text on Cocoa programming, which could be considered the gold standard of UI programming tutorials. In general, you will be able to get yourself started on Qt programming with this text. However, the lack of quality control will make the experience a little less pleasing than it otherwise could have been.The Book of Qt 4: The Art of Building Qt Applications Overview
Cross-platform development is a kind of holy grail, and Trolltech's Qt toolkit may well be the most promising solution yet to this development challenge. Qt is widely used for the development of GUI applications as well as console tools and servers, and it's especially appealing to programmers who need to write cross-platform applications to run on Linux/Unix, Mac, and Windows machines without having to rewrite for each platform.

The Book of Qt 4 offers an in-depth explanation of Qt 4 that goes beyond the common focus on C++ programming. Author Daniel Molkentin uses practical examples to explain features like the signal/slot concept and the event system, as he guides you through developing applications with and without Qt's graphical GUI builder, Qt Designer. And as a core KDE developer, Molkentin's head is full of real-world problems and solutions that he peppers liberally throughout The Book of Qt 4, making it a resource that you'll consult time and again. You'll find coverage of:

Tools for creating dialogs
GUI design with the Qt Designer
Widget layout and dialog construction
Data visualization using Qt's model/view concept
The QtSql module and the graphics library Arthur
File handling, XML, processes, and network connections
Databases and threading
Event handling and using drag and drop
Internationalization and debugging

As well as lots of useful hints on how to use Qt's datatypes, containers, and algorithms and how to develop user-friendly applications.

Whether you're already a Qt developer or you're just considering Qt for cross-platform development, you'll find The Book of Qt 4 to be indispensable.
