Description

This class is the base object class for a factory used to create an accessible object for a specific GType. The function 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.

Details

AtkObjectFactory

typedef struct _AtkObjectFactory AtkObjectFactory;

The AtkObjectFactory structure should not be accessed directly.

atk_object_factory_create_accessible ()

AtkObject*          atk_object_factory_create_accessible
                                                        (AtkObjectFactory *factory,
                                                         GObject *obj);

Provides an AtkObject that implements an accessibility interface on behalf of obj

factory : The AtkObjectFactory associated with obj's object type
obj : a GObject
Returns : an AtkObject that implements an accessibility interface on behalf of obj

atk_object_factory_get_accessible_type ()

GType               atk_object_factory_get_accessible_type
                                                        (AtkObjectFactory *factory);

Gets the GType of the accessible which is created by the factory.

factory : an AtkObjectFactory
Returns : the type of the accessible which is created by the factory. The value G_TYPE_INVALID is returned if no type if found.

atk_object_factory_invalidate ()

void                atk_object_factory_invalidate       (AtkObjectFactory *factory);

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

factory : an AtkObjectFactory to invalidate
