If you are using\n * the JavaScript API, you should use the {@link GestureWatcher} directly. The\n * purpose of this widget is to expose the watcher's ability to track gestures\n * and set relevant CSS properties via the HTML API. See\n * {@link GestureWatcher.trackGesture}.\n *\n * -----\n *\n * To use with auto-widgets (HTML API) (see\n * {@link Settings.settings.autoWidgets | settings.autoWidgets}), the following\n * CSS classes or data attributes are recognized:\n * - `lisn-track-gesture` class or `data-lisn-track-gesture` attribute set on\n *   the element that constitutes the widget.\n *\n * See below examples for what values you can use set for the data attributes\n * in order to modify the configuration of the automatically created widget.\n *\n * @example\n * This will track user gestures over this element and set the relevant CSS\n * properties. It will use the default {@link GestureWatcher} options.\n *\n * ```html\n * <div class=\"lisn-track-gesture\"></div>\n * ```\n *\n * @example\n * As above but with custom settings.\n *\n * ```html\n * <div data-lisn-track-gesture=\"prevent-default=false\n *                               | min-delta-x=-100\n *                               | max-delta-x=100\n *                               | min-delta-y=-100\n *                               | max-delta-y=100\n *                               | min-delta-z=0.5\n *                               | max-delta-z=2\"\n * ></div>\n * ```\n
