BiEvent

The event class is the core class describing the event objects passed around in an event.

This class extends BiObject and therefore all methods and fields available for BiObject are also available for BiEvent .

Constructor

new BiEvent ( sType )

Parameters

Name	Type	Optional	Default	Descripton
sType	String			The type (name) of the event. The argument is used in the addEventListener to know which listeners to notify.

Properties

Name	Type	get	set	Descripton
bubbles	Boolean			Whether the event bubbles to the parent component.
currentTarget	BiEventTarget			The BiEventTarget that the event handler was added to. This is not the same as the target in case the event has bubbled.
defaultPrevented	Boolean			If the default event should be prevented. This becomes true after calling preventDefault
propagationStopped	Boolean			If the propagation has been stopped. This is true after stopPropagation has been called and this means that bubbling events will not bubble up to the parent of the current target component
target	BiEventTarget			The BiEventTarget that initially dispatched the event.
type	String			The type (name) of the event.
