如何检测 Windows 10 是否处于平板电脑模式 [英] How to detect if Windows 10 is in tablet mode

问题描述

我正在尝试寻找一种方法来检测 Windows 10 是否处于平板电脑模式.请注意，这不是关于查询用户是否拥有平板电脑 - 这可以通过 GetSystemMetrics(SM_CONVERTIBLESLATEMODE) 解决.就我而言，上述函数始终返回 0 - 无论 Win10 是否处于平板电脑模式.

这个没有结尾的线程似乎表明没有 WinAPI 调用可以检测平板电脑模式.我希望不是这样，因为无论是否处于平板电脑模式，操作系统都会发布不同的 WM 消息.在平板电脑模式下 WM_SHOWWINDOW is not sent 这意味着我需要解决如果 Windows 10 处于平板电脑模式，则应用程序会有所不同.

我可以将接收到 WM_SHOWWINDOW 消息后当前触发的代码移动到其他地方(就在 ShowWindow 被调用之后)，但随后我得到了一个 WM_DPICHANGED 带有空参数的消息.

解决方案

你可以使用 UIViewSettings.UserInteractionMode @Raymond 指出.

I'm trying to find a method to detect if Windows 10 is in tablet mode or not. Please note, this is not about querying whether the user has a Tablet PC or not - that can be solved with GetSystemMetrics(SM_CONVERTIBLESLATEMODE). In my case the above function always returns 0 - whether Win10 is in tablet mode or not.

This thread without an epilogue seems to suggest that there is no WinAPI call that could detect Tablet mode. I hope that isn't the case, since there are different WM messages posted by the OS if it's in tablet mode or not. In tablet mode WM_SHOWWINDOW isn't sent which means I need to address the launching of the application differently if Windows 10 is in tablet mode.

I could just move the code that is currently triggered after receiving the WM_SHOWWINDOW message somewhere else (just after ShowWindow is called), but then I get a WM_DPICHANGED message with null parameters.

解决方案

You can use UIViewSettings.UserInteractionMode @Raymond pointed out.
