| 项目描述: |
Examples of three different ways to share events amongst multiple objects. For this demo, timers are shared by multiple instances of an extremely simple clock control. But the event being shared isn't what's important, rather it's the techniques used to share the events (which could be any sort of system callback, or whatever). The methods used include sharing a global form instance with an intrinsic timer control on it, a global class instance that raises events in response to a system clock callback, and a collection-based method that fires secondary interface methods of each member in response to system clock callbacks. By using a secondary interface, different sorts of objects can all receive notifications via a simple loop.
这个项目演示了在多个对象中共享事件的三种不同方式。其中，一个非常简单的时钟控件的多个实例共享定时器。但共享事件并不是重要的，重要的是用于共享事件的技术（可以是任意的系统回调函数，等等）。使用的方法有用一个定时器控件来共享一个全局窗体实例；一个可以响应系统时钟回调的全局类的实例；一种基于集合的方法，使用每个接口的间接接口方法来响应系统时钟回调。通过使用间接接口，不同种类的对象可以在循环中检索通知。
