This class is the primary class for accessibility support via the Accessibility ToolKit (ATK).
Objects which are instances of Object (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 Object may also be
queried as to whether they implement other ATK interfaces (e.g. Action,
Component, etc.), as appropriate to the role which a given UI component plays in a user
All UI components in an application which provide useful information or services to the user must provide corresponding
Object 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
Object implementation is insufficient, via instances of a new Object subclass.
