public interface Widget

extends Service, Serializable

Widget is a component with a graphical representation (via render(OutputData)), event handling (via event(Path, InputData).

As every Widget has a lifecycle of a Component, it also has a request cycle. Request cycle starts with update(InputData) which gives the Widget the data from the request as InputData.

If an event is routed to this widget, event(Path, InputData) is invoked.
