添加WPF中所有元素事件的侦听器 [英] Add listener for all element events in WPF

问题描述

我想在一个调用中钩住所有可用的元素事件。一些这样的事情：

I would like to hook for all available element events in one call. Some thing like this:

elem.AddHandler(AnyRoutedEvent, (RoutedEventHandler)handler)

我该怎么做？

推荐答案

尝试这样获取Button类型上的所有事件...您可以替换其他类型。

Try this to get all events on the Button type... You can substitute a different type.

RoutedEvent[] events = EventManager.GetRoutedEventsForOwner(typeof(Button));

foreach (RoutedEvent e in events)
   elem.AddHandler(e, handler);

您还可以替换以下内容获取所有类型的所有路由事件，但这将是相当的列表！

You can also substitute the following to get ALL routed events for ALL types, but that would be quite a list!

RoutedEvent[] events = EventManager.GetRoutedEvents();
