¿WPF tiene un gesto de tocar y mantener? No puedo encontrar un evento para eso, así que intenté implementar uno para mí. Yo se que hayStylus clase pero en WPF no me ayuda. Si no hay uno, ahí está mi código:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Timers;
namespace WebControlTouch
{
    /// <summary>
    /// Due to lack of Touch-and-Hold gesture, here is implementation of it. Stupid M$.
    /// </summary>
    public static class Touch_and_Hold
    {
        #region Constructor + methods
        /// <summary>
        /// Static constructor which creates timer object with 1000ms interval, also sets parameters of Timer.
        /// </summary>
        static Touch_and_Hold()
        {
            gestureTimer = new Timer(1000);
            gestureTimer.AutoReset = false;
            gestureTimer.Elapsed += gestureTimer_Elapsed;
        }
        /// <summary>
        /// On elasped (time ofc)
        /// </summary>
        /// <seealso cref="gestureTimer"/>        
        static void gestureTimer_Elapsed(object sender, ElapsedEventArgs e)
        {
            occured = true;
        }
        /// <summary>
        /// Call it on OnTouchDown event.
        /// It will start timer and will count time of touch
        /// </summary>
        /// <returns>Returns that gesture occured</returns>
        public static void onTouch()
        {
            gestureTimer.Start();
        }

        /// <summary>
        /// Call it on touch up mainwindow event (or somewhere else)
        /// It stops gesture timer
        /// </summary>
        public static void onTouchUp()
        {
        occured = false;
        }
        #endregion 
        #region Members + properties
        /// <summary>
        /// Timer for measuring touchTime
        /// </summary>
        private static Timer gestureTimer;
        /// <summary>
        /// Do tap-and-hold occured
        /// </summary>
        private static bool occured = false;
        /// <summary>
        /// Property for getting occured flag
        /// </summary>
        public static bool occuredGesture
        {
            get { return occured; }
        }
        #endregion
    }

}

En caso afirmativo, dígame el nombre del evento. Si no, intenta llevarme a la solución. Cualquier ayuda será muy apreciada.
