E4AP uses a pub/sub approach to events.
FIXME: Pulled the following from the e4 image viewer demo, but it uses an OSGi EventAdmin directly rather than IEventBroker.
Notification of an Event
@Inject @Optional public void setInput(@UIEventTopic(Part.EVENT_NAME) PojoObject input) { ... }
Posting an Event
public class Part { final static public String EVENT_NAME = "org/eclipse/e4/demo/app/value"; @Inject private EventAdmin eventAdmin; @PostConstruct void init() { ... viewer.addSelectionChangedListener(new ISelectionChangedListener() { public void selectionChanged(SelectionChangedEvent event) { Object selected = ((StructuredSelection) event.getSelection()).getFirstElement(); if (eventAdmin != null) EventUtils.post(eventAdmin, EVENT_NAME, selected); } }); .... }
