# AtkRegistry

## Name

AtkRegistry -- An object used to store the GType of the factories used to create an accessible object for an object of a particular GType.

## Synopsis

    struct      AtkRegistry;
    void        atk_registry_set_factory_type   (AtkRegistry *registry,
                                                 GType type,
                                                 GType factory_type);
    GType       atk_registry_get_factory_type   (AtkRegistry *registry,
                                                 GType type);
    AtkObjectFactory* atk_registry_get_factory  (AtkRegistry *registry,
                                                 GType type);
    AtkRegistry* atk_get_default_registry       (void);

## Description

## Details

### struct AtkRegistry

    struct AtkRegistry;

The AtkRegistry structure should not be accessed directly.

### atk_registry_set_factory_type ()

    void        atk_registry_set_factory_type   (AtkRegistry *registry,
                                                 GType type,
                                                 GType factory_type);

Associate an AtkObjectFactory subclass with a GType. Note: The associated `factory_type` will thereafter be responsible for the creation of new AtkObject implementations for instances appropriate for `type`.

`registry` :

  the AtkRegistry in which to register the type association

`type` :

  an AtkObject type

`factory_type` :

  an AtkObjectFactory type to associate with `type`. Must implement AtkObject appropriate for `type`.

### atk_registry_get_factory_type ()

    GType       atk_registry_get_factory_type   (AtkRegistry *registry,
                                                 GType type);

Provides a GType indicating the AtkObjectFactory subclass associated with `type`.

`registry` :

  an AtkRegistry

`type` :

  a GType with which to look up the associated AtkObjectFactory subclass

Returns :

  a GType associated with type `type`

### atk_registry_get_factory ()

    AtkObjectFactory* atk_registry_get_factory  (AtkRegistry *registry,
                                                 GType type);

Gets an AtkObjectFactory appropriate for creating AtkObjects appropriate for `type`.

`registry` :

  an AtkRegistry

`type` :

  a GType with which to look up the associated AtkObjectFactory

Returns :

  an AtkObjectFactory appropriate for creating AtkObjects appropriate for `type`.

### atk_get_default_registry ()

    AtkRegistry* atk_get_default_registry       (void);

Gets a default implementation of the AtkObjectFactory/type registry. Note: For most toolkit maintainers, this will be the correct registry for registering new AtkObject factories. Following a call to this function, maintainers may call atk_registry_set_factory_type() to associate an AtkObjectFactory subclass with the GType of objects for whom accessibility information will be provided.

Returns :

  a default implementation of the AtkObjectFactory/type registry
