GI.Atk.Objects.ObjectFactory

This class is the base object class for a factory used to create an accessible object for a specific GType. The function registrySetFactoryType is normally called to store in the registry the factory type to be used to create an accessible of a particular GType.

Exported types

newtype ObjectFactory

Memory-managed wrapper type.

Constructors

ObjectFactory (ManagedPtr ObjectFactory)

type ParentTypes ObjectFactory = Object ': ([] :: [Type])

class (GObject o, IsDescendantOf ObjectFactory o) => IsObjectFactory o

Type class for types which can be safely cast to ObjectFactory, for instance with toObjectFactory.

Instances

(GObject o, IsDescendantOf ObjectFactory o) => IsObjectFactory o

Defined in GI.Atk.Objects.ObjectFactory

toObjectFactory :: (MonadIO m, IsObjectFactory o) => o -> m ObjectFactory

Cast to ObjectFactory, for types for which this is known to be safe. For general casts, use castTo.

noObjectFactory :: Maybe ObjectFactory

A convenience alias for Nothing :: Maybe ObjectFactory.

Methods

createAccessible

objectFactoryCreateAccessible

Arguments

:: (HasCallStack, MonadIO m, IsObjectFactory a, IsObject b)

=> a

factory: The ObjectFactory associated with obj's object type

-> b

obj: a Object

-> m Object

Returns: an Object that implements an accessibility interface on behalf of obj

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

getAccessibleType

objectFactoryGetAccessibleType

Arguments

:: (HasCallStack, MonadIO m, IsObjectFactory a)

=> a

factory: an ObjectFactory

-> m GType

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

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

invalidate

objectFactoryInvalidate

Arguments

:: (HasCallStack, MonadIO m, IsObjectFactory a)

=> a

factory: an ObjectFactory to invalidate

-> m ()

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.
