检测Windows 8 Store App是否具有触摸屏 [英] Detect whether a Windows 8 Store App has a touch screen

问题描述

Win 8 Store App UI的某些元素会根据用户是否有触摸屏而更改.例如，当ScrollViewer在非触摸屏上呈现时，它会显示垂直滚动条.在触摸屏上，滚动条被隐藏.

There are certain elements of Win 8 Store App UI that change based on whether the user has a touch screen. For example, a ScrollViewer, when rendered on a non-touch screen shows a vertical scrollbar. On a touch screen, the scrollbar is hidden.

我想为非触摸屏用户量身定制应用程序UI，添加其他控件.有谁知道是否可以检测用户是否有触摸屏?

I would like to tailor my application UI, adding extra controls, for non-touch screen users. Does anyone know if it is possible to detect whether a user has a touch screen?

推荐答案

您可以使用Windows.Devices.Input命名空间来检测各种功能(触摸，键盘，鼠标等).例如， TouchCapabilities 该类具有TouchPresent属性，您可以检查该属性是否有可用的数字转换器.

You can use the Windows.Devices.Input namespace to detect various capabilities (touch, keyboard, mouse, etc.). For example, the TouchCapabilities class has a TouchPresent property you could check to see if there's a digitizer available.

看看输入:设备功能示例看到他们的行动.
