41  * #AtkObject (or instances of AtkObject-derived types) are queried
42  * for properties which relate basic (and generic) properties of a UI
43  * component such as name and description.  Instances of #AtkObject

45  * interfaces (e.g. #AtkAction, #AtkComponent, etc.), as appropriate
46  * to the role which a given UI component plays in a user interface.
47  * 
48  * All UI components in an application which provide useful
49  * information or services to the user must provide corresponding
50  * #AtkObject instances on request (in GTK+, for instance, usually on
51  * a call to #gtk_widget_get_accessible ()), either via ATK support
52  * built into the toolkit for the widget class or ancestor class, or
53  * in the case of custom widgets, if the inherited #AtkObject
54  * implementation is insufficient, via instances of a new #AtkObject
55  * subclass.
