The more popular Linux becomes, the more developers want to build graphical applications that run in Linux/Unix environments -- and Gtk+ 1.2 offers a powerful toolset for doing so. In this start-to-finish tutorial and reference, respected Linux/Unix developer Syd Logan covers everything programmers need to begin building powerful graphical applications with Gtk+ 1.2 immediately. Logan begins by reviewing the fundamentals of Linux/Unix programming with C; then walks through constructing a simple Gtk+ application. Next, he introduces each key category of Gtk+ widget, including base widgets; menu and layout widgets; range, scrollbar, and scale widgets; container widgets; and text widgets. The book also includes detailed coverage of creating and using dialogs, and writing new widgets, as well as expert introductions to GLIB and GDK.
