GI.GLib.Structs.SourceCallbackFuncs

The GSourceCallbackFuncs struct contains functions for managing callback objects.

Exported types

newtype SourceCallbackFuncs

Memory-managed wrapper type.

Constructors

SourceCallbackFuncs (ManagedPtr SourceCallbackFuncs)

Instances

WrappedPtr SourceCallbackFuncs

Methods

wrappedPtrCalloc :: IO (Ptr SourceCallbackFuncs)

wrappedPtrCopy :: SourceCallbackFuncs -> IO SourceCallbackFuncs

wrappedPtrFree :: Maybe (FunPtr (Ptr SourceCallbackFuncs -> IO ()))

(~) AttrOpTag tag AttrSet => Constructible SourceCallbackFuncs tag

Methods

new :: MonadIO m => (ManagedPtr SourceCallbackFuncs -> SourceCallbackFuncs) -> [AttrOp SourceCallbackFuncs tag] -> m SourceCallbackFuncs

newZeroSourceCallbackFuncs :: MonadIO m => m SourceCallbackFuncs

Construct a SourceCallbackFuncs struct initialized to zero.

noSourceCallbackFuncs :: Maybe SourceCallbackFuncs

A convenience alias for Nothing :: Maybe SourceCallbackFuncs.

Properties

ref

No description available in the introspection data.

clearSourceCallbackFuncsRef :: MonadIO m => SourceCallbackFuncs -> m ()

Set the value of the “ref” field to Nothing. When overloading is enabled, this is equivalent to

clear #ref

getSourceCallbackFuncsRef :: MonadIO m => SourceCallbackFuncs -> m (Maybe SourceCallbackFuncsRefFieldCallback)

Get the value of the “ref” field. When overloading is enabled, this is equivalent to

get sourceCallbackFuncs #ref

setSourceCallbackFuncsRef :: MonadIO m => SourceCallbackFuncs -> FunPtr C_SourceCallbackFuncsRefFieldCallback -> m ()

Set the value of the “ref” field. When overloading is enabled, this is equivalent to

set sourceCallbackFuncs [ #ref := value ]

unref

No description available in the introspection data.

clearSourceCallbackFuncsUnref :: MonadIO m => SourceCallbackFuncs -> m ()

Set the value of the “unref” field to Nothing. When overloading is enabled, this is equivalent to

clear #unref

getSourceCallbackFuncsUnref :: MonadIO m => SourceCallbackFuncs -> m (Maybe SourceCallbackFuncsUnrefFieldCallback)

Get the value of the “unref” field. When overloading is enabled, this is equivalent to

get sourceCallbackFuncs #unref

setSourceCallbackFuncsUnref :: MonadIO m => SourceCallbackFuncs -> FunPtr C_SourceCallbackFuncsUnrefFieldCallback -> m ()

Set the value of the “unref” field. When overloading is enabled, this is equivalent to

set sourceCallbackFuncs [ #unref := value ]
