class anychart.graphics.vector.Element Improve this Doc

Abstract class for all vector elements, such as groups and primitives. Due to the fact that this class is a child of from goog.events.EventTarget all its childs can work with events.

Returns:

string - Returns element identifier.
Sets element identifier.

Name Type Description
value string Custom identifier.

Returns:

anychart.graphics.vector.Element - Self instance for method chaining.

listen

Adds an event listener. A listener can only be added once to an object and if it is added again the key for the listener is returned. Note that if the existing listener is a one-off listener (registered via listenOnce), it will no longer be a one-off listener after a call to listen().

Params:

Name Type Description
type string The event type id.
listener function Callback method.
useCapture boolean Whether to fire in capture phase (defaults to false).

listenOnce

Adds an event listener that is removed automatically after the listener fired once. If an existing listener already exists, listenOnce will do nothing. In particular, if the listener was previously registered via listen(), listenOnce() will not turn the listener into a one-off listener. Similarly, if there is already an existing one-off listener, listenOnce does not modify the listeners (it is still a once listener).

Params:

Name Type Description
type string The event type id.
listener function Callback method.
useCapture boolean Whether to fire in capture phase (defaults to false).
listenerScope SCOPE Object in whose scope to call the listener.

Returns:

Object - Unique key for the listener.
