getAxis
Arguments
| :: (HasCallStack, MonadIO m, IsGestureStylus a) | |
| => a |
|
| -> AxisUse |
|
| -> m (Bool, Double) | Returns: |
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 |
|
| -> 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 down,
motion, up or proximity
signal handlers.
Since: 3.24
new
Arguments
| :: (HasCallStack, MonadIO m, IsWidget a) | |
| => a |
|
| -> 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
