Infos

There are only two mainstream solutions for building the graphical interface of Linux-based desktop applications, and GTK+ (GIMP Toolkit) is one of them. It is a necessary technology for all Linux programmers. This book guides the reader through the complexities of GTK+, laying the groundwork that allows the reader to make the leap from novice to professional. Beginning with an overview of key topics such as widget choice, placement, and behavior, readers move on to learn about more advanced issues. Replete with real-world examples, the developer can quickly take advantages of the concepts presented within to begin building his own projects.

Andrew Krause is the creator of OpenLDev, an integrated development environment that focuses on C, C++, Gtk+, and Gtkmm project management. He is attending Pennsylvania State University with a major in computer engineering. Andrew has eight years of experience with many computer and web programming languages such as C, C++, Perl, PHP, and others. He also designs flight hardware for the Low Ionosphere Measurement Satellite project at Penn State.

GTK+ is one of the most influential graphical toolkits for the Linux operating system. It is the technology upon which the GNOME and XFCE desktop environments are based, and its crucial to have clear understanding of its complexities to build even a simple Linux desktop application. Foundations of GTK+ Development guides you through these complexities, laying the foundation that will allow you to cross from novice to professional.Foundations of GTK+ Development is aimed at C programmers and presents numerous real-life examples that you can immediately put to use in your projects. Some familiarity with C programming is assumed, as the book delves into new topics from the beginning. Topics like object inheritance are covered early on to allow for complete understanding of code examples later. And the provided examples are real-life situations that can help you get a head start on your own applications.
