Unfortunately, this book fall short of expectations. It is little more than an overview of the basic funtionality is this wonderful rich featured package. Almost 30 pages of the total 270 pages are given over to Tables listing public and protected member functions all of which can be found in the Qt reference documentation. Appendix A takes up 55 pages of reference material, leaving a mear 180 pages left on the discussion of using Qt. The editorial review states this book contains a discussion of using COM/DCOM. This must have been a mistake since the subject of COM/DCOM is not mentioned anywhere in the book. Clearly, this book does not live up to expectations and there is no it could possibly cover such a vast topic in so few pages. Consequently, I could not recommend this book to anybody regardless of skill level
