WPF：有没有可能到"路线"普通的鼠标事件触摸事件在Windows 7 [英] WPF: Is there a possibility to "route" ordinary mouse events to touch events in Windows 7

问题描述

我目前正在开发使用C＃（.NET 4.0）和WPF为Windows 7 $ B $触摸屏的应用程序B我的问题是触摸屏我可此刻的驱动程序仅会生成鼠标事件。 （制造商可惜不提供正版的Windows 7驱动程序）
所以，目前我不能够正确地做测试。

I'm currently developing a touch screen application using C# (.NET 4.0) and WPF for Windows 7. My problem is that the driver of the touch screen I have available at the moment only generates mouse events. (The manufacturer unfortunately does not provide a genuine Windows 7 driver) So, currently I'm not able to do tests properly.

有没有一种通用的方法告诉Windows 7的某一个设备应该是一个触摸设备？（虽然这 - 当然 - 只能提供单一的触摸事件）

Is there a generic way to tell Windows 7 that a certain device is supposed to be a touch device (although this -- of course -- could only provide single touch events)?

勾选此。

有一个MouseTouchDevice.cs文件看起来像这样。它转换成普通鼠标事件，操作事件

Check this. http://blakenui.codeplex.com/. There is a MouseTouchDevice.cs file that looks like this. It converts normal mouse events to Manipulation events.

/// <summary>
/// Used to translate mouse events into touch events, enabling a unified 
/// input processing pipeline.
/// </summary>
/// <remarks>This class originally comes from Blake.NUI - http://blakenui.codeplex.com</remarks>
