<!-- ##### SECTION Title ##### -->
AtkObject

<!-- ##### SECTION Short_Description ##### -->

The base object class for the Accessibility Toolkit API.

<!-- ##### SECTION Long_Description ##### -->
<para>
This class is the primary class for accessibility support via
the Accessibility ToolKit (ATK).  Objects which are instances
of #AtkObject (or instances of AtkObject-derived types) are
queried for properties which relate basic (and generic) properties of a
UI component such as name and description.  Instances of #AtkObject
may also be queried as to whether they implement other ATK interfaces
(e.g. #AtkAction, #AtkComponent, etc.), as appropriate to the role
which a given UI component plays in a user interface.
</para>
<para>All UI components in an application which provide useful
information or services to the user must provide corresponding
#AtkObject instances on request (in GTK+, for instance, usually
on a call to #gtk_widget_get_accessible ()), either via ATK support
built into the toolkit for the widget class or ancestor class, or in
the case of custom widgets, if the inherited #AtkObject implementation
is insufficient, via instances of a new #AtkObject subclass. 
</para>

<!-- ##### ENUM AtkRole ##### -->
<para>
These are the built-in enumerated roles that UI components can have in
ATK.  Other roles may be added at runtime, so an AtkRole >=
ATK_ROLE_LAST_DEFINED is not necessarily an error.
