问题描述
我开发了一个应用程序，可以在三星 Series 7 平板电脑上运行.此应用程序是使用 WPF、.NET 4.5 和 C# 开发的.
I have developed an application to run on a Samsung Series 7 tablet. This application was developed using WPF, .NET 4.5, and C#.
我的问题是有时一个按钮在第一次被点击时没有收到输入.例如，Window1 上有一个 OpenWindow2Button，用于打开 Window2.关闭 Window2，然后尝试按下 DoSomethingElseButton.我第一次点击按钮时，没有任何反应.第二次按钮按预期工作.当我点击 Window1 上的 DisplayMediaElement 时，也会出现同样的问题.
My problem is that sometimes a button does not receive input the first time it is tapped. For example, Window1 has a OpenWindow2Button on it that opens Window2. Close Window2 and then try to push DoSomethingElseButton. The first time I tap the button, nothing happens. The second time the button works like expected. The same problem also occurs when I tap a DisplayMediaElement that is on Window1.
一个有趣的事实是，如果我使用手写笔或鼠标，则问题不存在.
An interesting fact is that if I use a stylus or mouse, the problem is non-existent.
我的猜测是 Window 或 DisplayMediaElement 没有接收点击输入的焦点.(但是为什么它有接收触控笔或鼠标输入的焦点?)这是一个功能还是一个错误?是否可以在第一次点击按钮时接收触摸输入?
My guess is that the Window or DisplayMediaElement does not have focus to receive a tap input. (But then why does it have focus to receive a stylus or mouse input?) Is this a feature or a bug? Is it possible to receive touch input the first time a button is tapped?
推荐答案
也许有时它不会将手势识别为点击"而是拖动"(或任何其他手势类型)?我想我前段时间遇到了问题.
Maybe sometimes it does not recognize gesture as 'tap' but as 'drag' (or any other gesture type)? I think i had a problem with it some time ago.
