Usage sample

listen

listen(type, listener, useCapture, listenerScope)

Adds an event listener to an implementing object.

Detailed description

The listener can be added to an object once, and if it is added one more time, its key will be returned.
Note Notice that if the existing listener is one-off (added using listenOnce), it will cease to be such after calling the listen() method.

Params:

Name	Type	Default	Description
type	string		The event type id.
listener	function		Callback method. Function that looks like `function(event){ // event.actualTarget - actual event target // event.currentTarget - current event target // event.iterator - event iterator // event.originalEvent - original event // event.point - event point // event.pointIndex - event point index }`.
useCapture	boolean	false	Whether to fire in capture phase. Learn more about capturing https://javascript.info/bubbling-and-capturing

Detailed description

After the event is called, its handler will be deleted.
If the event handler being added already exists, listenOnce will do nothing.
Note In particular, if the handler is already registered using listen(), listenOnce() will not make it one-off. Similarly, if a one-off listener already exists, listenOnce will not change it (it wil remain one-off).

Params:
