双击Windows 7平板电脑按钮

[英]Windows 7 Tablet Button Double-Tap

原文 2013-05-07 07:48:45 0 1 c#/ wpf/ windows/ .net-4.5

I have developed an application to run on a Samsung Series 7 tablet. 我已经开发了一个可以在Samsung Series 7平板电脑上运行的应用程序。 This application was developed using WPF, .NET 4.5, and C#. 此应用程序是使用WPF，.NET 4.5和C＃开发的。

My problem is that sometimes a button does not receive input the first time it is tapped. 我的问题是，有时某个按钮在第一次被点击时没有收到输入。 For example, Window1 has a OpenWindow2Button on it that opens Window2. 例如，Window1上有一个OpenWindow2Button，可以打开Window2。 Close Window2 and then try to push DoSomethingElseButton. 关闭Window2，然后尝试按DoSomethingElseButton。 The first time I tap the button, nothing happens. 第一次点击按钮时，什么也没有发生。 The second time the button works like expected. 第二次按钮按预期工作。 The same problem also occurs when I tap a DisplayMediaElement that is on Window1. 当我点击Window1上的DisplayMediaElement时，也会发生相同的问题。

An interesting fact is that if I use a stylus or mouse, the problem is non-existent. 一个有趣的事实是，如果我使用手写笔或鼠标，则该问题将不存在。

My guess is that the Window or DisplayMediaElement does not have focus to receive a tap input. 我的猜测是Window或DisplayMediaElement没有焦点来接收点击输入。 (But then why does it have focus to receive a stylus or mouse input?) Is this a feature or a bug? （但是，为什么它有焦点来接收手写笔或鼠标输入？）这是功能还是错误？ Is it possible to receive touch input the first time a button is tapped? 第一次点击按钮是否可以接收触摸输入？

Maybe sometimes it does not recognize gesture as 'tap' but as 'drag' (or any other gesture type)? 也许有时它不将手势识别为“轻击”，而是识别为“拖动”（或任何其他手势类型）？ I think i had a problem with it some time ago. 我想我前段时间有问题。
