Events

Events are an important component of the views framework. Events allow the view to interact with the framework on lifecycle changes (i.e. "framework eventsFramework Events") . such as deploy, create and destroy. As well, once a user has collection of views available, eventing allows the views to communicate with other views (i.e. "view eventsView Events").

Framework Events

To register to receive framework events, in the view.xml, specify a <view-class>this.is.my.view-clazz</view-class> which is a class that implements the View interface.

View Events

Views Events

Views can pass events between views. Obtain From the view context, you can obtain the ViewController object that allows you to register listeners for view events and to fire events for other listeners.

ViewController viewContext.getViewController();

Registering Listeners

A view can register an event Listener from (via the ViewController) for other views by view name, or by view name + version. When an Event is fired from the source view, all registered listeners will receive the event.

Firing and Receiving Events

1. Obtain the view controller and register a listener.
   

   viewContext.getViewController().registerListener(...);

2. Create an event.

3. Fire the event.
   viewContext.getViewController().fireEvent(event...);
   
   
4. The framework will notify all registered listeners. The listener implementation can process the event as appropriate.
   listener.notify(event)...)
