Struct TapRecognizer 

pub struct TapRecognizer { /* private fields */ }

Stateful tap gesture recognizer.

Implementations

impl TapRecognizer

pub fn new(settings: TapSettings) -> Self

Creates a tap recognizer with custom settings.

pub fn update( &mut self, pass: PointerEventPass, pointer_changes: &mut [PointerChange], within_bounds: bool, ) -> TapResult

Updates the recognizer with the current pointer pass and events.

Position source

Positions come from the samples themselves in a shared coordinate space.

Slop origin

The recorded press position anchors slop and movement. A press without a recorded position uses the first movement sample as its origin.

within_bounds

within_bounds is a semantic flag the caller computes from the node’s relative coordinates; it reports whether the pointer was inside this node when the update ran.

pub fn update_exclusive( &mut self, pass: PointerEventPass, pointer_changes: &mut [PointerChange], within_bounds: bool, ) -> TapResult

Recognizes taps while claiming each press before ancestor tap handlers.

Use for nested click targets. Claims preserve samples for drag and scroll observers that use Self::update.

pub fn cancel(&mut self)

Cancels the active press without producing a tap.
