Package org.nakedobjects.applib.events Description

Interaction events, corresponding to gestures in the user interface.

The applib does not provide any means of listening to these events directly, and typically domain objects would not be interested in them either. However, they can be subscribed to using the headlessviewer (which effectively provides a drop-in replacement for the DomainObjectContainer that implements the HeadlessViewer interface).
