new

eventControllerMotionNew

Arguments

:: (HasCallStack, MonadIO m, IsWidget a)

=> a

widget: a Widget

-> m EventControllerMotion

Returns: a new EventControllerMotion

Creates a new event controller that will handle motion events for the given widget.

Since: 3.24

Signals

enter

type C_EventControllerMotionEnterCallback = Ptr () -> CDouble -> CDouble -> Ptr () -> IO ()

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

type EventControllerMotionEnterCallback

Arguments

 = Double

x: the x coordinate

-> Double

y: the y coordinate

-> IO ()

Signals that the pointer has entered the widget.

afterEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionEnterCallback -> m SignalHandlerId

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

after eventControllerMotion #enter callback

genClosure_EventControllerMotionEnter :: MonadIO m => EventControllerMotionEnterCallback -> m (GClosure C_EventControllerMotionEnterCallback)

Wrap the callback into a GClosure.

mk_EventControllerMotionEnterCallback :: C_EventControllerMotionEnterCallback -> IO (FunPtr C_EventControllerMotionEnterCallback)

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

noEventControllerMotionEnterCallback :: Maybe EventControllerMotionEnterCallback

A convenience synonym for Nothing :: Maybe EventControllerMotionEnterCallback.

onEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionEnterCallback -> m SignalHandlerId

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

on eventControllerMotion #enter callback

wrap_EventControllerMotionEnterCallback :: EventControllerMotionEnterCallback -> C_EventControllerMotionEnterCallback

Wrap a EventControllerMotionEnterCallback into a C_EventControllerMotionEnterCallback.

leave

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

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

type EventControllerMotionLeaveCallback = IO ()

Signals that pointer has left the widget.

afterEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionLeaveCallback -> m SignalHandlerId

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

after eventControllerMotion #leave callback

genClosure_EventControllerMotionLeave :: MonadIO m => EventControllerMotionLeaveCallback -> m (GClosure C_EventControllerMotionLeaveCallback)

Wrap the callback into a GClosure.

mk_EventControllerMotionLeaveCallback :: C_EventControllerMotionLeaveCallback -> IO (FunPtr C_EventControllerMotionLeaveCallback)

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

noEventControllerMotionLeaveCallback :: Maybe EventControllerMotionLeaveCallback

A convenience synonym for Nothing :: Maybe EventControllerMotionLeaveCallback.

onEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionLeaveCallback -> m SignalHandlerId

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

on eventControllerMotion #leave callback

wrap_EventControllerMotionLeaveCallback :: EventControllerMotionLeaveCallback -> C_EventControllerMotionLeaveCallback

Wrap a EventControllerMotionLeaveCallback into a C_EventControllerMotionLeaveCallback.

motion

type C_EventControllerMotionMotionCallback = Ptr () -> CDouble -> CDouble -> Ptr () -> IO ()

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

type EventControllerMotionMotionCallback

Arguments

 = Double

x: the x coordinate

-> Double

y: the y coordinate

-> IO ()

Emitted when the pointer moves inside the widget.

afterEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionMotionCallback -> m SignalHandlerId

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

after eventControllerMotion #motion callback

genClosure_EventControllerMotionMotion :: MonadIO m => EventControllerMotionMotionCallback -> m (GClosure C_EventControllerMotionMotionCallback)

Wrap the callback into a GClosure.

mk_EventControllerMotionMotionCallback :: C_EventControllerMotionMotionCallback -> IO (FunPtr C_EventControllerMotionMotionCallback)

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

noEventControllerMotionMotionCallback :: Maybe EventControllerMotionMotionCallback

A convenience synonym for Nothing :: Maybe EventControllerMotionMotionCallback.

onEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionMotionCallback -> m SignalHandlerId

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

on eventControllerMotion #motion callback

wrap_EventControllerMotionMotionCallback :: EventControllerMotionMotionCallback -> C_EventControllerMotionMotionCallback

Wrap a EventControllerMotionMotionCallback into a C_EventControllerMotionMotionCallback.
