AtkRegistry

typedef struct _AtkRegistry 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
