Developers who write programs for GNOME use the GNOME API. Working with the GNOME API is preferable because the program will conform to the standard GNOME program look and feel. It also allows the developer to use the GNOME specific libraries in the program, greatly simplifying the development process. The Official GNOME 2 Developer's Guide is the official GNOME Foundation guide to programming GUIs and applications using the GTK+ and GNOME API. Developed in partnership with the GNOME Foundation, this book is for programmers working with the GNOME 2 desktop environment. Each section begins with an example program that serves as a tutorial, then develops into a reference on the topic. Includes abundant, well-annotated examples. Knowledge of the C programming language is required, but no GUI programming experience is necessary. - from Amzon
