RotationHandle

Read as Markdown

RotationHandle rotates its controller around the frame center. It sits 24 CSS pixels beyond the top edge and uses an 8 CSS-pixel visual with a default 24 CSS-pixel hit region. Provide a writable radians signal and enable rotate on the controller.

import { RotationHandle, useManipulation, useSignal } from "@pibbl/core";

const box = useSignal({ left: 40, top: 32, width: 180, height: 100 });
const rotation = useSignal(0);
const manipulation = useManipulation({ box, rotation, rotate: {} });

<RotationHandle controller={manipulation} />;
