Good introduction to QT
This is a very well written guide to QT programming, which covers use of most of the basic widgets and many of the more complex widgets such as table views. It also covers XML processing and many other sophisticated topics. The book covers some very difficult topics in plain and simple terms, which makes them much more accessible, and has very good examples for programming with the various widgets.
Unfortunately, the book is somewhat out of date. It only covers QT 3. Most users will want to use QT 4, the more recent version of the library. There are very significant differences between the two libraries, which limits the utility of this book.
Pros: Clear explanation of many fundamental widgets.
Cons: Does not yet cover QT4 (as of the second edition).
