如何识别输入事件来自触摸板或鼠标？ [英] How to identify an input event is from touchpad or mouse?

问题描述

Hi Teams，



我正在尝试集成（精确）触控板支持。我想要的是身份输入事件来自触摸板或鼠标。我阅读了https://msdn.microsoft.com/en-us/library/windows/desktop/hh454916(v=vs.85).aspx和https://msdn.microsoft.com/en-us/library/windows /desktop/hh448801(v=vs.85).aspx
并尝试调用GetPointerType，GetPointerInfo和GetCurrentInputMessageSource，这些都不能告诉触摸板的输入来自触摸板。 



我试过Windows 10，vs2017在XPS和Surfacebook上试过。这是我的演示代码https://github.com/chaopeng/tons-of-issues/tree/master/windows-cannot-identify-input-from-touchpad。



是否有任何配置丢失或我应该打电话给其他api？

Hi Teams,

I'm trying to integrate (Precision) Touchpad support. What I want is identity a input event is from Touchpad or mouse. I read https://msdn.microsoft.com/en-us/library/windows/desktop/hh454916(v=vs.85).aspx and https://msdn.microsoft.com/en-us/library/windows/desktop/hh448801(v=vs.85).aspx and tried call GetPointerType, GetPointerInfo and GetCurrentInputMessageSource, none of these can tell the input from touchpad is from touchpad. 

I tried on Windows 10, vs2017 on XPS and Surfacebook. Here is my demo code https://github.com/chaopeng/tons-of-issues/tree/master/windows-cannot-identify-input-from-touchpad.

Is there any configuration missing or I should call other api?

谢谢。

推荐答案

我认为（未经测试）INPUT_MESSAGE_DEVICE_TYPE枚举

对此任务有帮助：



INPUT_MESSAGE_DEVICE_TYPE枚举

INPUT_MESSAGE_SOURCE结构

https://msdn.microsoft.com/en-us/library/windows/desktop/hh448799（v = vs.85）的.aspx

I would think (untested) that the INPUT_MESSAGE_DEVICE_TYPE enumeration
would be helpful for this task:
