Signals

ContentDeserializeFunc

type C_ContentDeserializeFunc = Ptr ContentDeserializer -> IO ()

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

type ContentDeserializeFunc

Arguments

 = ContentDeserializer

deserializer: a ContentDeserializer

-> IO ()

The type of a function that can be registered with contentRegisterDeserializer. When the function gets called to operate on content, it can call functions on the deserializer object to obtain the mime type, input stream, user data, etc. for its operation.

dynamic_ContentDeserializeFunc

Arguments

:: (HasCallStack, MonadIO m, IsContentDeserializer a)

=> FunPtr C_ContentDeserializeFunc

-> a

deserializer: a ContentDeserializer

-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_ContentDeserializeFunc :: MonadIO m => ContentDeserializeFunc -> m (GClosure C_ContentDeserializeFunc)

Wrap the callback into a GClosure.

mk_ContentDeserializeFunc :: C_ContentDeserializeFunc -> IO (FunPtr C_ContentDeserializeFunc)

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

noContentDeserializeFunc :: Maybe ContentDeserializeFunc

A convenience synonym for Nothing :: Maybe ContentDeserializeFunc.

wrap_ContentDeserializeFunc :: Maybe (Ptr (FunPtr C_ContentDeserializeFunc)) -> ContentDeserializeFunc -> C_ContentDeserializeFunc

Wrap a ContentDeserializeFunc into a C_ContentDeserializeFunc.

ContentSerializeFunc

type C_ContentSerializeFunc = Ptr ContentSerializer -> IO ()

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

type ContentSerializeFunc

Arguments

 = ContentSerializer

serializer: a ContentSerializer

-> IO ()

The type of a function that can be registered with contentRegisterSerializer. When the function gets called to operate on content, it can call functions on the serializer object to obtain the mime type, output stream, user data, etc. for its operation.

dynamic_ContentSerializeFunc

Arguments

:: (HasCallStack, MonadIO m, IsContentSerializer a)

=> FunPtr C_ContentSerializeFunc

-> a

serializer: a ContentSerializer

-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_ContentSerializeFunc :: MonadIO m => ContentSerializeFunc -> m (GClosure C_ContentSerializeFunc)

Wrap the callback into a GClosure.

mk_ContentSerializeFunc :: C_ContentSerializeFunc -> IO (FunPtr C_ContentSerializeFunc)

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

noContentSerializeFunc :: Maybe ContentSerializeFunc

A convenience synonym for Nothing :: Maybe ContentSerializeFunc.

wrap_ContentSerializeFunc :: Maybe (Ptr (FunPtr C_ContentSerializeFunc)) -> ContentSerializeFunc -> C_ContentSerializeFunc

Wrap a ContentSerializeFunc into a C_ContentSerializeFunc.

SeatGrabPrepareFunc

type C_SeatGrabPrepareFunc = Ptr Seat -> Ptr Surface -> Ptr () -> IO ()

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

type SeatGrabPrepareFunc

Arguments

 = Seat

seat: the Seat being grabbed

-> Surface

surface: the Surface being grabbed

-> IO ()

Type of the callback used to set up surface so it can be grabbed. A typical action would be ensuring the surface is visible, although there's room for other initialization actions.

type SeatGrabPrepareFunc_WithClosures

Arguments

 = Seat

seat: the Seat being grabbed

-> Surface

surface: the Surface being grabbed

-> Ptr ()

userData: user data passed in seatGrab

-> IO ()

Type of the callback used to set up surface so it can be grabbed. A typical action would be ensuring the surface is visible, although there's room for other initialization actions.

drop_closures_SeatGrabPrepareFunc :: SeatGrabPrepareFunc -> SeatGrabPrepareFunc_WithClosures

A simple wrapper that ignores the closure arguments.

dynamic_SeatGrabPrepareFunc

Arguments

:: (HasCallStack, MonadIO m, IsSeat a, IsSurface b)

=> FunPtr C_SeatGrabPrepareFunc

-> a

seat: the Seat being grabbed

-> b

surface: the Surface being grabbed

-> Ptr ()

userData: user data passed in seatGrab

-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_SeatGrabPrepareFunc :: MonadIO m => SeatGrabPrepareFunc -> m (GClosure C_SeatGrabPrepareFunc)

Wrap the callback into a GClosure.

mk_SeatGrabPrepareFunc :: C_SeatGrabPrepareFunc -> IO (FunPtr C_SeatGrabPrepareFunc)

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

noSeatGrabPrepareFunc :: Maybe SeatGrabPrepareFunc

A convenience synonym for Nothing :: Maybe SeatGrabPrepareFunc.

noSeatGrabPrepareFunc_WithClosures :: Maybe SeatGrabPrepareFunc_WithClosures

A convenience synonym for Nothing :: Maybe SeatGrabPrepareFunc_WithClosures.

wrap_SeatGrabPrepareFunc :: Maybe (Ptr (FunPtr C_SeatGrabPrepareFunc)) -> SeatGrabPrepareFunc_WithClosures -> C_SeatGrabPrepareFunc

Wrap a SeatGrabPrepareFunc into a C_SeatGrabPrepareFunc.
