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 | | | 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 | | | The BiEventTarget that initially dispatched the event. | |
type | String | | | The type (name) of the event. |
