Description

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.

Synopsis

newtype ObjectFactory = ObjectFactory (ManagedPtr ObjectFactory)
class (GObject o, IsDescendantOf ObjectFactory o) => IsObjectFactory o
toObjectFactory :: (MonadIO m, IsObjectFactory o) => o -> m ObjectFactory
objectFactoryCreateAccessible :: (HasCallStack, MonadIO m, IsObjectFactory a, IsObject b) => a -> b -> m Object
objectFactoryGetAccessibleType :: (HasCallStack, MonadIO m, IsObjectFactory a) => a -> m GType
objectFactoryInvalidate :: (HasCallStack, MonadIO m, IsObjectFactory a) => a -> m ()

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

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

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

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

Methods

Overloaded methods

createAccessible

objectFactoryCreateAccessible Source #

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 Source #

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 Source #

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.
