Qt is a toolkit for building graphical user interfaces (GUIs) in Linux, Unix and even Windows. Qt is much easier to use than the standard Motif toolkit for Unix systems, and its applications are portable from one environment to another. Qt can even emulate the look-and-feel of Windows in Unix, providing Windows users with native-looking interfaces. As the popularity of Linux moves it closer to the mainstream, the need for guidance in generating user-friendly interfaces is sure to grow. Programming with QT, 2nd Edition is the book programmers will use to create a Qt-based GUI in Unix or Linux. Updated for the new Version 2.3, it shows how to use all of the Qt GUI elements, and covers advanced topics like 2D transformations and drag-and-drop. Among the many features adding value to the second edition is a new chapter on network programming.
