Struct GestureRecognizer 

pub struct GestureRecognizer { /* private fields */ }

Stateful gesture recognizer that transforms raw events into semantic events.

Call process for each incoming Event. Call check_long_press periodically (e.g., on tick) to detect long-press gestures.

Implementations

impl GestureRecognizer

pub fn new(config: GestureConfig) -> Self

Create a new gesture recognizer with the given configuration.

pub fn process(&mut self, event: &Event, now: Instant) -> Vec<SemanticEvent>

Process a raw event, returning any semantic events produced.

Most events produce 0 or 1 semantic events. A mouse-up after a multi-click sequence may produce both a Click and a DoubleClick.

pub fn check_long_press(&mut self, now: Instant) -> Option<SemanticEvent>

Check for long press timeout. Call periodically (e.g., on tick).

Returns Some(LongPress { .. }) if the mouse has been held stationary beyond the configured threshold.

pub fn is_dragging(&self) -> bool

Whether a drag is currently in progress.

pub fn reset(&mut self)

Reset all gesture state to initial idle.

pub fn config(&self) -> &GestureConfig

Get a reference to the current configuration.

pub fn set_config(&mut self, config: GestureConfig)

Update the configuration.
