Description

This class is the base object class for a factory used to create an accessible object for a specific GType. The method atk.Registry.set_factory_type() is normally called to store in the registry the factory type to be used to create an accessible of a particular GType.

    def create_accessible(obj)

obj :

a gobject.GObject

Inform the factory that it is no longer being used to create accessibles. When called, the factory may need to inform the atk.Object objects it has created that they need to be re-instantiated. Note: primarily used for runtime replacement of atk.ObjectFactory objects in object registries.

    def get_accessible_type()
