toGestureStylus :: (MonadIO m, IsGestureStylus o) => o -> m GestureStylus Source #

Cast to GestureStylus, for types for which this is known to be safe. For general casts, use castTo.

Methods

getAxis

gestureStylusGetAxis Source #

Arguments

:: (HasCallStack, MonadIO m, IsGestureStylus a) 
=> a

gesture: a GestureStylus

-> AxisUse

axis: requested device axis

-> m (Bool, Double)

Returns: TRUE if there is a current value for the axis

Returns the current value for the requested axis. This function must be called from either the GestureStylus:down, GestureStylus:motion, GestureStylus:up or GestureStylus:proximity signals.

Since: 3.24

getDeviceTool

gestureStylusGetDeviceTool Source #

Arguments

:: (HasCallStack, MonadIO m, IsGestureStylus a) 
=> a

gesture: a GestureStylus

-> m (Maybe DeviceTool)

Returns: The current stylus tool

Returns the DeviceTool currently driving input through this gesture. This function must be called from either the GestureStylus::down, GestureStylus::motion, GestureStylus::up or GestureStylus::proximity signal handlers.

Since: 3.24

new

gestureStylusNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsWidget a) 
=> a

widget: a Widget

-> m GestureStylus

Returns: a newly created stylus gesture

Creates a new GestureStylus.

Since: 3.24

Signals

down

type GestureStylusDownCallback = Double -> Double -> IO () Source #

No description available in the introspection data.

afterGestureStylusDown :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusDownCallback) -> m SignalHandlerId Source #

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

after gestureStylus #down 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.

onGestureStylusDown :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusDownCallback) -> m SignalHandlerId Source #

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

on gestureStylus #down callback

motion

type GestureStylusMotionCallback = Double -> Double -> IO () Source #

No description available in the introspection data.

afterGestureStylusMotion :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusMotionCallback) -> 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 gestureStylus #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.

onGestureStylusMotion :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusMotionCallback) -> 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 gestureStylus #motion callback

proximity

type GestureStylusProximityCallback = Double -> Double -> IO () Source #

No description available in the introspection data.

afterGestureStylusProximity :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusProximityCallback) -> m SignalHandlerId Source #

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

after gestureStylus #proximity 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.

onGestureStylusProximity :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusProximityCallback) -> m SignalHandlerId Source #

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

on gestureStylus #proximity callback

up

type GestureStylusUpCallback = Double -> Double -> IO () Source #

No description available in the introspection data.

afterGestureStylusUp :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusUpCallback) -> m SignalHandlerId Source #

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

after gestureStylus #up 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.

onGestureStylusUp :: (IsGestureStylus a, MonadIO m) => a -> ((?self :: a) => GestureStylusUpCallback) -> m SignalHandlerId Source #

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

on gestureStylus #up callback
