Implementations

impl GestureRecognizer

pub fn new(finger_count: usize) -> Self

pub fn with_gesture_types(self, types: GestureTypes) -> Self

pub fn with_exact_finger_count(self, exact: bool) -> Self

pub fn process(&mut self, contacts: &[Contact]) -> Option<GestureEvent>

pub fn reset(&mut self) -> Option<GestureEvent>

pub fn timeout(&mut self) -> Option<GestureEvent>

pub fn events_from_device(self, device: &Device) -> GestureStream

Spawn a gesture stream from one multitouch device.

pub fn events_from_monitor(self, monitor: &Monitor) -> GestureStream
