Description

Interface for classes capable of having callbacks to handle events.

Public Methods

HandleEventHandle an event, most often by executing the callbacks associated with the event.
HasBubbleHandlersReturn true if event handlers for the event propagation bubble up phase have been attached on this object.
HasCaptureHandlersReturn true if event handlers for the event propagation capture phase have been attached on this object.
RegisterCallbackAdd an event handler on the instance. If the handler has already been registered on the same phase (capture or bubbling), this will have no effect.
UnregisterCallbackRemove callback from the instance.
