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.

C++ GUI Programming with Qt 4 (2nd Edition) (Prentice Hall Open Source Software Development Series) ReviewThis book contains the most thorough coverage of the many functionalities in Qt. The second edition is also the most current of all the books (a fleeting feature, but noteworthy depending on what you want to learn). Its well written and after over 1 year of working with the book I have yet to find any erroneous information of code.
We own all of the Qt books, but we use this one for teaching Qt in our Internship program. The Basic Qt Section starts simple and builds up from individual widgets and signals/slots to dialogs to windows to the full fancy application functionality (menus, toolbars, docking objects, tabs, MDI windows) that Qt makes pretty effortless in a number of ways.
The book covers the very powerful Model-View structure very well. We have also benefitted from the XML, layout and networking chapters. The book has also been of help in dealing with look and feel issues (stylesheets and subclassing QStyle). It also covers a number of fascinating topics that I've read about but just never used professionally, such as plug-ins.
Some criticized its style of covering the development and structure of a small (spreadsheet-type) application. This is actually the most beneficial way to learn how to use the library since you wind up with the ability to see how the pieces interact with each other. Its easy to show how a QAction works; showing how to make it flow through an MDI to the right window, however, is much easier in a whole application context. This book is not a book on computer science (algorithms, etc); its certainly a book on the specifics of how to work with the Qt library and its also a book on application development generally. The downloadable code from InformIT is a nice bonus.
The Qt library, like any actively developed library, is constantly evolving so it should be no surprise that there are some features added since publication. I think its more a positive about Qt than a negative about the book. Each chapter is well organized, with each chapter covering one of the many aspects of Qt programming. Its impossible to cover every class and method because the Qt library is huge. This book clocks in at over 700 pages and, in my opinion, more than hits the highlights. I have no problem hitting the web or documentation for more in depth info. But with this book, I feel like I've got enough background to tackle the issues.
Lastly, in response to those who criticize Qt: I have tried a number of the other major libraries and I have found nothing better for GUI than Qt. But Qt covers so much more. It provides data types and containers (eg QString, QList, QHash), model-view-controller GUI, networking, regular expressions, signals-slots. I've moved my apps from using a mix of MFC, boost, and other libraries to just using Qt. Qt is highly consistent and all data can be moved from one class to the next with minimal effort. It truly is the best available and this is easily our book of choice for training with the Qt library.C++ GUI Programming with Qt 4 (2nd Edition) (Prentice Hall Open Source Software Development Series) Overview
The Only Official, Best-Practice Guide to Qt 4.3 Programming
Using Trolltech's Qt you can build industrial-strength C++ applications that run natively on Windows, Linux/Unix, Mac OS X, and embedded Linux without source code changes. 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.
