WindowEventHandlers

The WindowEventHandlers mixin describes the event handlers common to several interfaces like Window, or HTMLBodyElement (en-US) and HTMLFrameSetElement (en-US). Each of these interfaces can implement additional specific event handlers.

참고: WindowEventHandlers is a mixin and not an interface; you can't actually create an object of type WindowEventHandlers.
