AtkObject
The base object class for the Accessibility Toolkit API.
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.
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.
See also: #AtkObjectFactory, #AtkRegistry.
( GTK+ users see also #GtkAccessible).

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.

These enumerated "layer values" are used when determining which UI
rendering layer a component is drawn into, which can help in making
determinations of when components occlude one another.

This interface provides an alternative means of obtaining AtkObjects
from a GOBject instance, and for querying whether a GObject instance
provides ATK functionality.
