Description

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.

Synopsis

newtype Registry = Registry (ManagedPtr Registry)
class (GObject o, IsDescendantOf Registry o) => IsRegistry o
toRegistry :: (MonadIO m, IsRegistry o) => o -> m Registry
noRegistry :: Maybe Registry
registryGetFactory :: (HasCallStack, MonadIO m, IsRegistry a) => a -> GType -> m ObjectFactory
registryGetFactoryType :: (HasCallStack, MonadIO m, IsRegistry a) => a -> GType -> m GType
registrySetFactoryType :: (HasCallStack, MonadIO m, IsRegistry a) => a -> GType -> GType -> m ()

Methods

getFactory

registryGetFactory Source #

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 Source #

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 Source #

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.
