Expand description

Identify the moves of one touch contact in TouchMoveArgs.

Fields§

§touch: TouchId

Identify the touch contact or finger.

Multiple points of contact can happen in the same device at the same time, this ID identifies each uninterrupted contact. IDs are unique only among other concurrent touches on the same device, after a touch is ended an ID may be reused.

§touch_propagation: EventPropagationHandle

Handle across the lifetime of touch.

See TouchInputArgs::touch_propagation for more details.

§moves: Vec<(DipPoint, Option<TouchForce>)>

Coalesced moves of the touch since last event.

Last entry is the latest position.

§velocity: DipVector

Velocity in device independent pixels per second.

The velocity is computed from the 4 non-coalesced move events. If is zero before the fourth event.

§hits: HitTestInfo

Hit-test result for the latest touch point in the window.

§target: InteractionPath

Full path to the top-most hit in hits.
