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.

Signals

down

type C_GestureStylusDownCallback = Ptr () -> CDouble -> CDouble -> Ptr () -> IO () Source #

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

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

No description available in the introspection data.

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

Wrap the callback into a Closure.

mk_GestureStylusDownCallback :: C_GestureStylusDownCallback -> IO (FunPtr C_GestureStylusDownCallback) Source #

A convenience synonym for Nothing :: Maybe GestureStylusDownCallback.

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