# BubblingEvent

typedef

Helper type that allows describing bubbling event. Extends `TEvent` so that:

* the event is called with [`BubblingEventInfo`](module_engine_view_observer_bubblingeventinfo-BubblingEventInfo.md)\` instead of [`EventInfo`](module_utils_eventinfo-EventInfo.md), and
* [`BubblingCallbackOptions`](module_engine_view_observer_bubblingemittermixin-BubblingCallbackOptions.md) can be specified as additional options.
