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.
