ATK - Accessibility Toolkit | |
|---|---|---|---|---|
AtkRegistryAtkRegistry — An object used to store the GType of the factories used to create an accessible object for an object of a particular GType. |

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);
The AtkRegistry is normally used to create appropriate ATK "peers" for user interface components. Application developers usually need only interact with the AtkRegistry by associating appropriate ATK implementation classes with GObject classes via the atk_registry_set_factory_type call, passing the appropriate GType for application custom widget classes.
typedef struct _AtkRegistry AtkRegistry;
The AtkRegistry structure should not be accessed directly.
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.

the AtkRegistry in which to register the type association |
|
an AtkObject type |
|
an AtkObjectFactory type to associate with type. Must
implement AtkObject appropriate for type.
|
GType atk_registry_get_factory_type (AtkRegistry *registry, GType type);
Provides a GType indicating the AtkObjectFactory subclass
associated with type.
|
an AtkRegistry |
|
a GType with which to look up the associated AtkObjectFactory subclass |
Returns : |
a GType associated with type type
|
AtkObjectFactory* atk_registry_get_factory (AtkRegistry *registry, GType type);
Gets an AtkObjectFactory appropriate for creating AtkObjects
appropriate for type.
|
an AtkRegistry |
|
a GType with which to look up the associated AtkObjectFactory |
Returns : |
an AtkObjectFactory appropriate for creating AtkObjects
appropriate for type.
|
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 |
