public class Accessible : Object
The Accessible class is the base class for accessible implementations for Widget subclasses.
It is a thin wrapper around Object, which adds facilities for associating a widget with its accessible object.
An accessible implementation for a third-party widget should derive from Accessible and implement the suitable interfaces from ATK, such as Text or Selection. To establish the connection between the widget class and its corresponding acccessible implementation, override the get_accessible vfunc in Widget.
