Part I. GTK+ Overview

GTK+ is a library for creating graphical user interfaces. It works on many UNIX-like platforms, Windows, and on framebuffer devices. GTK+ is released under the GNU Library General Public License (GNU LGPL), which allows for flexible licensing of client applications. GTK+ has a C-based object-oriented architecture that allows for maximum flexibility. Bindings for other languages have been written, including C++, Objective-C, Guile/Scheme, Perl, Python, TOM, Ada95, Free Pascal, and Eiffel.

GTK+ depends on the following libraries:

GLib

A general-purpose utility library, not specific to graphical user interfaces. GLib provides many useful data types, macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on.

Pango

Pango is a library for internationalized text handling. It centers around the #PangoLayout object, representing a paragraph of text. Pango provides the engine for #GtkTextView, #GtkLabel, #GtkEntry, and other widgets that display text.

ATK

ATK is the Accessibility Toolkit. It provides a set of generic interfaces allowing accessibility technologies to interact with a graphical user interface. For example, a screen reader uses ATK to discover the text in an interface and read it to blind users. GTK+ widgets have built-in support for accessibility using the ATK framework.

GdkPixbuf

This is a small library which allows you to create #GdkPixbuf ("pixel buffer") objects from image data or image files. Use a #GdkPixbuf in combination with #GtkImage to display images.

GDK

GDK is the abstraction layer that allows GTK+ to support multiple windowing systems. GDK provides drawing and window system facilities on X11, Windows, and the Linux framebuffer device.

GTK+

The GTK+ library itself contains widgets, that is, GUI components such as #GtkButton or #GtkTextView.
