public interface EventTrigger

Provides support for triggering an event from a given parts of a component or using various events.

Used by features such as FileDownloaderConnector and BrowserWindowOpenerConnector to listen to a given event on a given element. The component is the one responsible for deciding the element and the event to listen to.

This is the client side interface.
