Qt lets programmers use a single source tree for applications that will run on Windows 98 to XP, Mac OS X, Linux, Solaris, HP-UX, and many other versions of Unix with X11. The Qt libraries and tools are also part of Qtopia Core, a product that provides its own window system on top of embedded Linux.

The purpose of this book is to teach you how to write GUI programs using Qt 4. The book starts with “Hello Qt” and quickly progresses to more advanced topics, such as creating custom widgets and providing drag and drop. The text is complemented by a CD that contains the source code of the example programs. The CD ...
