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.
Synopsis
- newtype EventControllerMotion = EventControllerMotion (ManagedPtr EventControllerMotion)
- class (GObject o, IsDescendantOf EventControllerMotion o) => IsEventControllerMotion o
- toEventControllerMotion :: (MonadIO m, IsEventControllerMotion o) => o -> m EventControllerMotion
- eventControllerMotionNew :: (HasCallStack, MonadIO m, IsWidget a) => a -> m EventControllerMotion
- type EventControllerMotionEnterCallback = Double -> Double -> IO ()
- afterEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionEnterCallback) -> m SignalHandlerId
- onEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionEnterCallback) -> m SignalHandlerId
- type EventControllerMotionLeaveCallback = IO ()
- afterEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionLeaveCallback) -> m SignalHandlerId
- onEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionLeaveCallback) -> m SignalHandlerId
- type EventControllerMotionMotionCallback = Double -> Double -> IO ()
- afterEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionMotionCallback) -> m SignalHandlerId
- onEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionMotionCallback) -> m SignalHandlerId
Exported types
newtype EventControllerMotion Source #
Memory-managed wrapper type.

Instances
class (GObject o, IsDescendantOf EventControllerMotion o) => IsEventControllerMotion o Source #
Type class for types which can be safely cast to EventControllerMotion
, for instance with toEventControllerMotion
.

toEventControllerMotion :: (MonadIO m, IsEventControllerMotion o) => o -> m EventControllerMotion Source #
Cast to EventControllerMotion
, for types for which this is known to be safe. For general casts, use castTo

new
eventControllerMotionNew Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

-> m EventControllerMotion | Returns: a new |
Creates a new event controller that will handle motion events
for the given widget
.
Since: 3.24
Signals
enter
type EventControllerMotionEnterCallback Source #
Signals that the pointer has entered the widget.
afterEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: 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
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self
parameter.
Note that this requires activating the ImplicitParams
GHC extension.
onEventControllerMotionEnter :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: 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
leave
type EventControllerMotionLeaveCallback = IO () Source #
Signals that pointer has left the widget.
afterEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: 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
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self
parameter.
Note that this requires activating the ImplicitParams
GHC extension.
onEventControllerMotionLeave :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: 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
motion
type EventControllerMotionMotionCallback Source #
Emitted when the pointer moves inside the widget.
afterEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: 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
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self
parameter.
Note that this requires activating the ImplicitParams
GHC extension.
onEventControllerMotionMotion :: (IsEventControllerMotion a, MonadIO m) => a -> ((?self :: a) => EventControllerMotionMotionCallback) -> m SignalHandlerId Source #
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
