GTK is a library for creating graphical user interfaces. It
|
|
works on many UNIX-like platforms, Windows, and OS X.
|
|
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 many other languages have
|
|
been written, including C++, Objective-C, Guile/Scheme, Perl, Python,
|
|
TOM, Ada95, Free Pascal, and Eiffel.

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.
