区分C#中的Click事件和DoubleClick事件 [英] Distinguishing between Click and DoubleClick events in C#

问题描述

我目前有一个NotifyIcon作为Windows窗体应用程序的一部分.我想在图标的双击上显示/隐藏表格，并在单击时显示气球提示.我将这两个功能分开工作，但是找不到让应用程序区分单击和双击的方法.现在，它将双击视为两次单击.

I currently have a NotifyIcon as part of a Windows Form application. I would like to have the form show/hide on a double click of the icon and show a balloon tip when single clicked. I have the two functionalities working separately, but I can't find a way to have the app distinguish between a single click and double click. Right now, it treats a double click as two clicks.

如果检测到第二次单击，是否可以阻止单击事件?

Is there a way to block the single click event if there is a second click detected?

推荐答案

不幸的是，对 NotifyIcon 类的 MouseClick 事件建议的处理方法不起作用-在我的测试中 e.MouseClicks 始终为0，也可以从

Unfortunately the suggested handling of MouseClick event doesn't work for NotifyIcon class - in my tests e.MouseClicks is always 0, which also can be seen from the reference source.

我看到的相对简单的方法是通过使用表单级别标志， async 处理程序和 Task.Delay 延迟对 Click 事件的处理.代码>:

The relatively simple way I see is to delay the processing of the Click event by using a form level flag, async handler and Task.Delay :

bool clicked;

private async void OnNotifyIconClick(object sender, EventArgs e)
{
    if (clicked) return;
    clicked = true;
    await Task.Delay(SystemInformation.DoubleClickTime);
    if (!clicked) return;
    clicked = false;
    // Process Click...
}

private void OnNotifyIconDoubleClick(object sender, EventArgs e)
{
    clicked = false;
    // Process Double Click...
}

唯一的缺点是在我的环境中， Click 的处理被延迟了半秒( DoubleClickTime 为500毫秒).

The only drawback is that in my environment the processing of the Click is delayed by half second (DoubleClickTime is 500 ms).
