C# 如何在WPF中的按钮悬停延迟一段时间后显示堆栈面板？

我有一个按钮，鼠标在这个按钮上悬停两秒钟，我想打开堆栈面板

xaml代码：

<StackPanel x:Name="spPinDetailsPopup" Height="200" Width="240" Visibility="Hidden">
     <!--it contains label control which have text to display-->
</StackPanel>
<Button x:Name="btnDisplayPopUp" MouseEnter="DisplayPopUpOnMouseEnter"/>

我使用了堆栈面板作为一个弹出窗口来显示控制信息

当前结果：堆栈面板立即显示

预期结果： 只有当我们将鼠标光标放在按钮上超过2秒时，堆栈面板才应打开。

有什么解决办法吗？

为什么不使用工具提示

    <Button ToolTip="Some Text" ToolTipService.InitialShowDelay="2000"/>

由于

工具提示

是一个

对象

，因此您可以根据自己的喜好配置布局，而不仅仅是一些文本

解决方案：

我在全局级别创建了一个Dispatchermer对象来控制打开弹出窗口的时间间隔

private static DispatcherTimer _popUpOpeningTimer = new DispatcherTimer();

void DisplayPopUpOnMouseEnter(object sender, MouseEventArgs e)
{
    // if we do not have DispatcherTimer set then only initialize it 
    if (_popUpOpeningTimer == null)
    {
          _popUpOpeningTimer = new DispatcherTimer();
    }
    else // this means that dispatcher timer is already initialized, so do nothing
    {
         // do nothing
    }
    // stop the timer if it is already set so that we can start new timer
    _popUpOpeningTimer.Stop();

    _popUpOpeningTimer.Interval = new TimeSpan(0, 0, 1);

    _popUpOpeningTimer.Tick += new EventHandler((senderObject, eventArguments) => DisplayPopUp(senderObject, eventArguments, btnDisplayPopUp));

    // start the timer for opening the details popup
    _popUpOpeningTimer.Start();  
}

private void DisplayPopUp(object sender, EventArgs e, Button button)
{
    if(button.IsMouseOver)
    {
         spPinDetailsPopup.Visibility = Visibility.Visible;
    }
    else
    {
         // do nothing
    }
}

是的，试试看，我们会帮助你。正如你在上面写的，如果你没有很好地展示你的尝试，这个问题就太广泛了。如果/当你修正你的问题，使其足够好，值得回答时，你需要确保你也明确你所说的“打开堆栈面板”的意思。

StackPanel

对象不是“可关闭”的，所以不清楚“打开”一个对象意味着什么。感谢各位的回答，我已经更新了问题：）@Leblanc，用户要求在工具提示中显示简短信息，在弹出窗口中显示详细信息，所以我将stack panel用作弹出窗口。

private static DispatcherTimer _popUpOpeningTimer = new DispatcherTimer();

void DisplayPopUpOnMouseEnter(object sender, MouseEventArgs e)
{
    // if we do not have DispatcherTimer set then only initialize it 
    if (_popUpOpeningTimer == null)
    {
          _popUpOpeningTimer = new DispatcherTimer();
    }
    else // this means that dispatcher timer is already initialized, so do nothing
    {
         // do nothing
    }
    // stop the timer if it is already set so that we can start new timer
    _popUpOpeningTimer.Stop();

    _popUpOpeningTimer.Interval = new TimeSpan(0, 0, 1);

    _popUpOpeningTimer.Tick += new EventHandler((senderObject, eventArguments) => DisplayPopUp(senderObject, eventArguments, btnDisplayPopUp));

    // start the timer for opening the details popup
    _popUpOpeningTimer.Start();  
}

private void DisplayPopUp(object sender, EventArgs e, Button button)
{
    if(button.IsMouseOver)
    {
         spPinDetailsPopup.Visibility = Visibility.Visible;
    }
    else
    {
         // do nothing
    }
}
