O WPF possui um gesto de tocar e segurar?
O WPF possui um gesto de tocar e segurar? Não consigo encontrar um evento para isso, então tentei implementar um para mim. Eu sei que existeStylus
classe, mas no WPF isso não me ajuda. Se não houver, existe o meu 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
}
}
Se sim, por favor me diga o nome do evento. Se não - tente me orientar para a solução. Qualquer ajuda será muito apreciada.
