Functions

addEventListener

fun <E : Event> EventTargetLike.addEventListener(type: EventType<E>, handler: (E) -> Unit, options: AddEventListenerOptions? = undefined)

The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.

dispatchEvent

open fun dispatchEvent(event: Event): Boolean

The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order.

removeEventListener

fun <E : Event> EventTargetLike.removeEventListener(type: EventType<E>, handler: (E) -> Unit, options: EventListenerOptions? = undefined)

The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target.

throwIfAborted

fun throwIfAborted()

The throwIfAborted() method throws the signal's abort AbortSignal.reason if the signal has been aborted; otherwise it does nothing.

when

fun <T : Event> when(type: EventType<T>, options: ObservableEventListenerOptions? = definedExternally): Observable<T>
