    class="ml-2 button small"
  >
    Press long
  </button>

  <button
    v-on-long-press="[onLongPressCallbackDirective, { delay: 1000, modifiers: { stop: true } }]"

## Type Declarations

export interface OnLongPressOptions {
  /**
   * Time in ms till `longpress` gets called
   *
   * @default 500
   */
  delay?: number | ((ev: PointerEvent) => number)
  modifiers?: OnLongPressModifiers
  /**
   * Allowance of moving distance in pixels,
   * The action will get canceled When moving too far from the pointerdown position.
   * @default 10
   */
  distanceThreshold?: number | false
  /**
   * Function called when the ref element is released.
   * @param duration how long the element was pressed in ms
   * @param distance distance from the pointerdown position
   * @param isLongPress whether the action was a long press or not
   */
  onMouseUp?: (duration: number, distance: number, isLongPress: boolean) => void
}
export interface OnLongPressModifiers {
  stop?: boolean
  once?: boolean
  prevent?: boolean
  capture?: boolean
  self?: boolean
}
export declare function onLongPress(
  target: MaybeElementRef,
  handler: (evt: PointerEvent) => void,
  options?: OnLongPressOptions,
): () => void
export type UseOnLongPressReturn = ReturnType<typeof onLongPress>
