Description
EventControllerMotion is an event controller meant for situations
where you need to track the position of the pointer.
This object was added in 3.24.

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 () Source #
Type for the callback on the (unwrapped) C side.
type EventControllerMotionEnterCallback Source #
Signals that the pointer has entered the widget.
afterEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionEnterCallback -> m SignalHandlerId Source #
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) Source #
Wrap the callback into a GClosure.
mk_EventControllerMotionEnterCallback :: C_EventControllerMotionEnterCallback -> IO (FunPtr C_EventControllerMotionEnterCallback) Source #
Generate a function pointer callable from C code, from a C_EventControllerMotionEnterCallback.
noEventControllerMotionEnterCallback :: Maybe EventControllerMotionEnterCallback Source #
A convenience synonym for Nothing :: Maybe EventControllerMotionEnterCallback
onEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionEnterCallback -> m SignalHandlerId Source #
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 Source #
leave
type C_EventControllerMotionLeaveCallback = Ptr () -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type EventControllerMotionLeaveCallback = IO () Source #
Signals that pointer has left the widget.
afterEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionLeaveCallback -> m SignalHandlerId Source #
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) Source #
Wrap the callback into a GClosure.
mk_EventControllerMotionLeaveCallback :: C_EventControllerMotionLeaveCallback -> IO (FunPtr C_EventControllerMotionLeaveCallback) Source #
Generate a function pointer callable from C code, from a C_EventControllerMotionLeaveCallback.
noEventControllerMotionLeaveCallback :: Maybe EventControllerMotionLeaveCallback Source #
A convenience synonym for Nothing :: Maybe EventControllerMotionLeaveCallback
onEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionLeaveCallback -> m SignalHandlerId Source #
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 Source #
motion
type C_EventControllerMotionMotionCallback = Ptr () -> CDouble -> CDouble -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type EventControllerMotionMotionCallback Source #
Emitted when the pointer moves inside the widget.
afterEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionMotionCallback -> m SignalHandlerId Source #
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) Source #
Wrap the callback into a GClosure.
mk_EventControllerMotionMotionCallback :: C_EventControllerMotionMotionCallback -> IO (FunPtr C_EventControllerMotionMotionCallback) Source #
Generate a function pointer callable from C code, from a C_EventControllerMotionMotionCallback.
noEventControllerMotionMotionCallback :: Maybe EventControllerMotionMotionCallback Source #
A convenience synonym for Nothing :: Maybe EventControllerMotionMotionCallback
onEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> EventControllerMotionMotionCallback -> m SignalHandlerId Source #
Connect a signal handler for the “motion” signal, to be run before the default handler.
