Interface EventListener

All Known Implementing Classes:
  XPathResultImpl

public interface EventListener

The `EventListener` interface is the primary method for handling events. Users implement the `EventListener` interface and register their listener on an `EventTarget` using the `AddEventListener` method. The users should also remove their `EventListener` from its `EventTarget` after they have completed using the listener.

When a `Node` is copied using the `cloneNode` method the `EventListener`s attached to the source `Node` are not attached to the copied `Node`. If the user wishes the same `EventListener`s to be added to the newly created copy the user must add them manually.

See also the Document Object Model (DOM) Level 2 Events Specification.

Since:
  DOM Level 2

Method Summary
`void` | `handleEvent(Event evt)` This method is called whenever an event occurs of the type for which the `EventListener` interface was registered.
