Reactive Framework / DoubleClick
我知道有一种简单的方法可以做到这一点 - 但它今晚打败了我......
我想知道两个事件是否在300毫秒之内发生，就像双击一样。
在300毫秒内点击两次左击鼠标 - 我知道这就是反应框架的构建 - 但是如果我能找到一个包含所有扩展操作系统的简单示例的好文档 - Throttle，BufferWithCount，BufferWithTime - 所有这些都不是'为我做这件事......

方法将为您提供值之间的时间。public static IObservable<Unit> DoubleClicks<TSource>( this IObservable<TSource> source, TimeSpan doubleClickSpeed, IScheduler scheduler) { return source .TimeInterval(scheduler) .Skip(1) .Where(interval => interval.Interval <= doubleClickSpeed) .RemoveTimeInterval(); }（我在这里使用了，因为点击将全部出现在一个线程上，因此不需要沉重的正常人）：public static IObservable<TSource> DoubleClicks<TSource>( this IObservable<TSource> source, TimeSpan doubleClickSpeed, IScheduler scheduler) { return source.Multicast<TSource, TSource, TSource>( () => new FastSubject<TSource>(), // events won't be multithreaded values => { return values .TimeInterval(scheduler) .Skip(1) .Where(interval => interval.Interval <= doubleClickSpeed) .RemoveTimeInterval() .Take(1) .Repeat(); }); }闪脖
。运营商可能是一个良好的开端。var ioClicks = Observable.FromEvent<MouseButtonEventHandler, RoutedEventArgs>( h => new MouseButtonEventHandler(h), h => btn.MouseLeftButtonDown += h, h => btn.MouseLeftButtonDown -= h); var ioTSClicks = ioClicks.Timestamp(); var iodblClicks = ioTSClicks.Zip(ioTSClicks.Skip(1), (r, l) => l.Timestamp - r.Timestamp) .Where(tspan => tspan.TotalMilliseconds < 300);[Fact] public void DblClick() { // setup var ioClicks = _scheduler.CreateHotObservable( OnNext(210, "click"), OnNext(220, "click"), OnNext(300, "click"), OnNext(365, "click")) .Timestamp(_scheduler); // act Func<IObservable<TimeSpan>> target = () => ioClicks.Zip(ioClicks.Skip(1), (r, l) => l.Timestamp - r.Timestamp) .Where(tspan => tspan.Ticks < 30); var actuals = _scheduler.Run(target); // assert Assert.Equal(actuals.Count(), 1); // + more } public static Recorded<Notification<T>> OnNext<T>(long ticks, T value) { return new Recorded<Notification<T>>( ticks, new Notification<T>.OnNext(value)); }
