  32  * @Short_description: An object used to store the GType of the
  33  * factories used to create an accessible object for an object of a
  34  * particular GType.
  35  * @Title:AtkObjectRegistry
  36  *
  37  * The AtkRegistry is normally used to create appropriate ATK "peers"
  38  * for user interface components.  Application developers usually need
  39  * only interact with the AtkRegistry by associating appropriate ATK
  40  * implementation classes with GObject classes via the
  41  * atk_registry_set_factory_type call, passing the appropriate GType
  42  * for application custom widget classes.
