Example 11 with DomEvent

use of com.vaadin.flow.dom.DomEvent in project flow by vaadin.

the class ElementListenersTest method addEventDataElement_eventTarget_usesMapEventTargetInstead.

@Test

    AtomicReference<DomEvent> capturedTarget = new AtomicReference<>();
    final DomListenerRegistration registration = parent.addEventListener(eventType, capturedTarget::set);
    final ElementListenerMap listenerMap = parent.getNode().getFeature(ElementListenerMap.class);
