Functions(1)

computeAutoScrollDelta

packages/core/src/utils/autoScroll.ts:21

Vertical scroll delta (px/frame) for a pointer at `mouseY` over a container whose viewport spans `rect.top`..`rect.bottom`. Negative scrolls up, positive down, 0 when the pointer is outside both edge zones. Speed ramps linearly from 0 at the edge-zone boundary to `AUTO_SCROLL_MAX_SPEED` at the edge.

declare function computeAutoScrollDelta(rect: {
    top: number;
    bottom: number;
}, mouseY: number): number;
