GI.Atk.Objects.Registry

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.

Exported types

Memory-managed wrapper type.

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

class (GObject o, IsDescendantOf Registry o) => IsRegistry o

Type class for types which can be safely cast to Registry, for instance with toRegistry.

Instances

(GObject o, IsDescendantOf Registry o) => IsRegistry o

Defined in GI.Atk.Objects.Registry

toRegistry :: (MonadIO m, IsRegistry o) => o -> m Registry

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

noRegistry :: Maybe Registry

A convenience alias for Nothing :: Maybe Registry.

Methods

getFactory

registryGetFactory

Arguments

:: (HasCallStack, MonadIO m, IsRegistry a)

=> a

registry: an Registry

-> GType

type: a GType with which to look up the associated ObjectFactory

-> m ObjectFactory

Returns: an ObjectFactory appropriate for creating AtkObjects appropriate for type.

Gets an ObjectFactory appropriate for creating AtkObjects appropriate for type.

getFactoryType

registryGetFactoryType

Arguments

:: (HasCallStack, MonadIO m, IsRegistry a)

=> a

registry: an Registry

-> GType

type: a GType with which to look up the associated ObjectFactory subclass

-> m GType

Returns: a GType associated with type type

Provides a GType indicating the ObjectFactory subclass associated with type.

setFactoryType

registrySetFactoryType

Arguments

:: (HasCallStack, MonadIO m, IsRegistry a)

=> a

registry: the Registry in which to register the type association

-> GType

type: an Object type

-> GType

factoryType: an ObjectFactory type to associate with type. Must implement AtkObject appropriate for type.

-> m ()

Associate an ObjectFactory subclass with a GType. Note: The associated factoryType will thereafter be responsible for the creation of new Object implementations for instances appropriate for type.
