GNOME provides support for accessibility devices using the ATK
framework. This framework defines a set of interfaces to which
graphical interface components adhere. This allows, for instance,
screen readers to read the text of an interface and interact with its
controls. ATK support is built into GTK+ and the rest of the GNOME
platform, so any application using GTK+ will have reasonable
accessibility support for free.

<p>
Nonetheless, you should be aware of accessibility issues when when
developing your applications. Although GTK+ interfaces provide
reasonable accessibility by default, you can often improve how well
your program behaves with accessibility tools by providing additional
information to ATK. If you develop custom widgets, you should ensure
that they expose their properties to ATK
