Struct DragRecognizer 

pub struct DragRecognizer { /* private fields */ }

Stateful drag gesture recognizer.

Implementations

impl DragRecognizer

pub fn new(settings: DragSettings) -> Self

Creates a drag recognizer with custom settings.

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

Updates the recognizer with the current pointer pass and events.

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 set_settings(&mut self, settings: DragSettings)

Replaces the recognizer settings while preserving active gesture state.

pub fn is_dragging(&self) -> bool

Returns whether dragging is currently active.
