我在视图中使用鼠标绑定来收听用户点击,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,我想忽略单击左键单击鼠标。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一个。有一个简单的方法吗?

我按照以下方式使用它(我使用了一个Button来测试它,你必须对它进行调整)。
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;
}
调整此代码(我主要是从https://stackoverflow.com/a/971676/4792869获得)
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");
}
