Enum Promotion

Source

pub enum Promotion {
    Distance,
    HoldOrSideways,
}

Expand description

How a press gets promoted to a drag - the policy half of the touch auto-sensor.

Variants§

§

Distance

Travel in any direction past the threshold begins the drag. The right policy for mouse and pen, and for touch surfaces that own every gesture (touch-action: none).

§

HoldOrSideways

Touch sharing the viewport with native vertical scrolling (touch-action: pan-y): a GestureEvent::Hold or a sideways-dominant pull (|dx| > |dy|) past the threshold begins the drag, while a vertical-dominant pull resolves the press as scroll intent - the machine returns to Idle and the browser’s pan takes the gesture (an exact diagonal counts as scroll).
