Undocumented in source.
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. gtk.Action, AtkComponent, etc.), as appropriate to the role which a given UI component plays in a user interface.
