GI.IBus.Objects.Object

IBusObject is the base object for all objects in IBus.

Exported types

newtype Object

Memory-managed wrapper type.

Constructors

Object (ManagedPtr Object)

Instances

Eq Object

Defined in GI.IBus.Objects.Object

Methods

(==) :: Object -> Object -> Bool

(/=) :: Object -> Object -> Bool

IsGValue Object

Convert Object to and from GValue with toGValue and fromGValue.

Defined in GI.IBus.Objects.Object

Methods

toGValue :: Object -> IO GValue

fromGValue :: GValue -> IO Object

GObject Object

Defined in GI.IBus.Objects.Object

Methods

gobjectType :: IO GType

HasParentTypes Object

Defined in GI.IBus.Objects.Object

type ParentTypes Object

Defined in GI.IBus.Objects.Object

type ParentTypes Object = '[Object]

class (GObject o, IsDescendantOf Object o) => IsObject o

Type class for types which can be safely cast to Object, for instance with toObject.

Instances

(GObject o, IsDescendantOf Object o) => IsObject o

Defined in GI.IBus.Objects.Object

toObject :: (MonadIO m, IsObject o) => o -> m Object

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

Methods

Overloaded methods

destroy

objectDestroy

Arguments

:: (HasCallStack, MonadIO m, IsObject a)

=> a

object: an Object to destroy.

-> m ()

Emit the "destroy" signal notifying all reference holders that they should release the Object.

The memory for the object itself won't be deleted until its reference count actually drops to 0; ibus_object_destroy merely asks reference holders to release their references. It does not free the object.

new

objectNew

Arguments

:: (HasCallStack, MonadIO m)

=> m Object

Returns: A newly allocated Object

Creates a new Object.

Signals

destroy

type C_ObjectDestroyCallback = Ptr () -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type ObjectDestroyCallback = IO ()

Destroy and free an IBusObject

See also: objectDestroy.

<note><para>Argument userData is ignored in this function.</para></note>

afterObjectDestroy :: (IsObject a, MonadIO m) => a -> ObjectDestroyCallback -> m SignalHandlerId

Connect a signal handler for the destroy signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after object #destroy callback

genClosure_ObjectDestroy :: MonadIO m => ObjectDestroyCallback -> m (GClosure C_ObjectDestroyCallback)

Wrap the callback into a GClosure.

mk_ObjectDestroyCallback :: C_ObjectDestroyCallback -> IO (FunPtr C_ObjectDestroyCallback)

Generate a function pointer callable from C code, from a C_ObjectDestroyCallback.

noObjectDestroyCallback :: Maybe ObjectDestroyCallback

A convenience synonym for Nothing :: Maybe ObjectDestroyCallback.

onObjectDestroy :: (IsObject a, MonadIO m) => a -> ObjectDestroyCallback -> m SignalHandlerId

Connect a signal handler for the destroy signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on object #destroy callback

wrap_ObjectDestroyCallback :: ObjectDestroyCallback -> C_ObjectDestroyCallback

Wrap a ObjectDestroyCallback into a C_ObjectDestroyCallback.
