WPF- 模拟触发Touch Events

原文:WPF- 模拟触发Touch Events

基于API：

  [DllImport("User32.dll")]

  public static extern bool InitializeTouchInjection(uint maxCount = 256, TouchFeedback feedbackMode = TouchFeedback.DEFAULT);

  [DllImport("User32.dll")]

  public static extern bool InjectTouchInput(int count, [MarshalAs(UnmanagedType.LPArray), In] PointerTouchInfo[] contacts);

实现效果：点击按钮，自动触发TouchDown事件、获取TouchEventArgs参数得到坐标，创建Line并设置X1、Y1属性，紧接着触发TouchMove、TouchUp事件，得到TouchUp的TouchEventArgs设置Line的X2、Y2属性。

private void MainWindow_TouchUp(object sender, TouchEventArgs e)

{

    System.Windows.Input.TouchPoint oPos = e.GetTouchPoint(this);

    this.ProxyLine.X2 = oPos.Position.X;

    this.ProxyLine.Y2 = oPos.Position.Y;

    this.GdRootZm.Children.Add(this.ProxyLine);

    Console.WriteLine("TouchID " + e.TouchDevice.Id + " TouchUp "

                       + oPos.Position.X + "    " + oPos.Position.Y);

}

private void MainWindow_TouchMove(object sender, TouchEventArgs e)

{

    System.Windows.Input.TouchPoint oPos = e.GetTouchPoint(this);

    Console.WriteLine("TouchID " + e.TouchDevice.Id + " TouchMove "

                      + oPos.Position.X + "    " + oPos.Position.Y);

}

private Line ProxyLine;

private void MainWindow_TouchDown(object sender, TouchEventArgs e)

{

    System.Windows.Input.TouchPoint oPos = e.GetTouchPoint(this);

    Line oLine = new Line();

    oLine.Stroke = new SolidColorBrush(Colors.Red);

    oLine.StrokeThickness = 2;

    oLine.X1 = oPos.Position.X;

    oLine.Y1 = oPos.Position.Y;

    this.ProxyLine = oLine;

    Console.WriteLine("TouchID " + e.TouchDevice.Id + "  TouchDown "

                      + oPos.Position.X + "    " + oPos.Position.Y);

}

Console Write Result：

  效果图如下：

private void SimulateTouch(int x, int y)

{

    // Touch Down Simulate

    PointerTouchInfo contact = MakePointerTouchInfo(x, y, 5, 1);

    PointerFlags oFlags = PointerFlags.DOWN | PointerFlags.INRANGE | PointerFlags.INCONTACT;

    contact.PointerInfo.PointerFlags = oFlags;

    bool bIsSuccess = TouchInjector.InjectTouchInput(1, new[] { contact });

    // Touch Move Simulate

    int nMoveIntervalX = this.GetRandomSeed().Next(-60, 60);

    int nMoveIntervalY = this.GetRandomSeed().Next(-60, 60);

    contact.Move(nMoveIntervalX, nMoveIntervalY);

    oFlags = PointerFlags.INRANGE | PointerFlags.INCONTACT | PointerFlags.UPDATE;

    contact.PointerInfo.PointerFlags = oFlags;

    TouchInjector.InjectTouchInput(1, new[] { contact });

    // Touch Up Simulate

    contact.PointerInfo.PointerFlags = PointerFlags.UP;

    TouchInjector.InjectTouchInput(1, new[] { contact });

}

 Multi Touch Also Support Like this：

private void BdrSimulateZm_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)

{

    // Touch Down Simulate

    int x1 = this.GetRandomSeed().Next(50, 1680 - 100);

    int y1 = this.GetRandomSeed().Next(50, 1080 - 100);

    PointerTouchInfo oContact1 = MakePointerTouchInfo(x1, y1, 5, 1);

    int x2 = this.GetRandomSeed().Next(50, 1680 - 100);

    int y2 = this.GetRandomSeed().Next(50, 1080 - 100);

    PointerTouchInfo oContact2 = MakePointerTouchInfo(x2, y2, 5, 1);

    PointerFlags oFlags = PointerFlags.DOWN | PointerFlags.INRANGE | PointerFlags.INCONTACT;

    oContact1.PointerInfo.PointerFlags = oFlags;

    oContact2.PointerInfo.PointerFlags = oFlags;

    TouchInjector.InjectTouchInput(2, new[] { oContact1, oContact2 });

    // Touch Move Simulate

    int nMoveIntervalX = this.GetRandomSeed().Next(-60, 60);

    int nMoveIntervalY = this.GetRandomSeed().Next(-60, 60);

    oContact1.Move(nMoveIntervalX, nMoveIntervalY);

    oContact2.Move(nMoveIntervalX, nMoveIntervalY);

    oFlags = PointerFlags.INRANGE | PointerFlags.INCONTACT | PointerFlags.UPDATE;

    oContact1.PointerInfo.PointerFlags = oFlags;

    oContact2.PointerInfo.PointerFlags = oFlags;

    TouchInjector.InjectTouchInput(2, new[] { oContact1 , oContact2 });

    // Touch Up Simulate

    oContact1.PointerInfo.PointerFlags = PointerFlags.UP;

    oContact2.PointerInfo.PointerFlags = PointerFlags.UP;

    TouchInjector.InjectTouchInput(2, new[] { oContact1, oContact2 });

}
