如何获得触摸屏使用鼠标事件，而不是触摸事件在C＃应用程序 [英] How to get Touchscreen to use Mouse Events instead of Touch Events in C# app

问题描述

我已经开发了覆盖PreviewMouseUp，PreviewMouseMove和PreviewMouseDown事件在一些自定义的控制，允许通过单击并拖动滚动滚动观众一个C＃应用程序。当使用鼠标拖动和滚动此自定义代码的工作在非触摸屏伟大的，但是当我使用一个真正的触摸屏上监视它不能正常工作，因为当显示器被触摸和拖PreviewMouseUp不被解雇一个手指。

I have developed a C# app that overrides the PreviewMouseUp, PreviewMouseMove, and PreviewMouseDown events in some custom controls to allow scrolling a scroll viewer by clicking and dragging. This custom code works great on non-touch screens when the mouse is used to drag and scroll, but when I use it on a real touch screen monitor it fails to work because the PreviewMouseUp does not get fired when the monitor is touched and dragged with a finger.

我希望能够用我的现有代码最小的变化。这将允许我使用鼠标单击/拖动，而在我的笔记本电脑进行调试，并使用触摸屏触摸/拖动。

I want to be able to use my existing code with minimal changes. This would allow me to use the mouse to click/drag while debugging on my laptop, and use the touch screen to touch/drag.

反正是有配置Windows 7的电脑把所有的触摸（PreviewTouchUp，的PreviewTouchDown和PreviewTouchMove）作为鼠标事件呢？

Is there anyway to configure a windows 7 computer to treat all touches (PreviewTouchUp, PreviewTouchDown, and PreviewTouchMove) as mouse events instead?

更新：我忘了​​提。我认为，如果触摸事件不处理，比.NET自动提高鼠标事件之后。这不会出现以上问题，即使没有我写的代码目前处理触摸事件。任何想法，为什么这可能是发生？

UPDATE: I forgot to mention. I thought that if the Touch events are not handled, than .NET automatically raises the Mouse events afterwards. This does not appear to be happening even though none of the code I wrote handles the Touch Events currently. Any ideas why this may be happening?

谢谢，

推荐答案

你可以做的就是用同样的方法为，是这样的：

What you can do is to use the same method for both, something like this:

protected override void OnPreviewMouseUp(MouseButtonEventArgs e)
{
    OnPreviewTouchMouseUp(e);
}

protected override void OnPreviewTouchUp(TouchEventArgs e)
{
    OnPreviewTouchMouseUp(e);
}

private void OnPreviewTouchMouseUp(EventArgs e)
{

}

唯一的区别是你得到的鼠标/触摸的坐标的方式：

The only difference will be the way you get the coordinates of the mouse/touch:

有关触摸：

e.GetTouchPoint(this).Position;

有关鼠标：

e.GetPosition(this);
