WPF：确定 MouseBinding 是单击还是双击

Question

我在我的视图中使用鼠标绑定来监听用户点击，如下所示：

<Path.InputBindings>
            <MouseBinding Gesture="LeftDoubleClick" Command="{Binding DoubleLeftClickProj}" />
            <MouseBinding Gesture="LeftClick" Command="{Binding SingleLeftClick}"/>
</Path.InputBindings>

我一次只需要一个鼠标手势。因此，如果我双击我的应用程序，我想忽略单击鼠标左键的绑定。可能就像在初始鼠标点击后等待 1-2 秒，然后决定应该调用哪个。有没有简单的方法可以做到这一点？

我按以下方式让它工作（我用一个按钮来测试它，你必须适应它）。

使用事件处理程序

<Button MouseDoubleClick="Button_MouseDoubleClick" Click="Button_Click"></Button>

将 DataContext 存储在静态变量中

private static object context;
public MainWindow()
{
    InitializeComponent();
    DataContext = new ViewModel();
    context = DataContext;
}

改编这段代码（我主要是从那里得到的）

private static DispatcherTimer myClickWaitTimer =
new DispatcherTimer(
    new TimeSpan(0, 0, 0, 1),
    DispatcherPriority.Background,
    mouseWaitTimer_Tick,
    Dispatcher.CurrentDispatcher);

private void Button_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    // Stop the timer from ticking.
    myClickWaitTimer.Stop();

    ((ICommand)DataContext).Execute("DoubleLeftClickProj");
    e.Handled = true;
}

private void Button_Click(object sender, RoutedEventArgs e)
{
    myClickWaitTimer.Start();
}

private static void mouseWaitTimer_Tick(object sender, EventArgs e)
{
    myClickWaitTimer.Stop();

    // Handle Single Click Actions
    ((ICommand)context).Execute("SingleLeftClick");
}
