Events Discussed

Discussion and relationships involved in Events

CategoryEvents
Notification Action / Reaction

The notification and the action are both signals. You discuss an 'observed' change in state, a 'recognized' click of the mouse or press of the button. And an event handler provides a simplistic form of reflexive behavior -- a triggered response, a reaction. The proper abstraction is a pairing: an observable 'trigger' (possibly abstracted over a context, allowing some variation on the observation) is paired with an executable 'action' (which may be adjusted by context) to form this 'reaction'. I'm studying this sort of material actively if you're interested in discussing it.


ActionEvent messages are meant to be received by Registered ActionListeners?


Messages may be acted upon immediately or may be inserted in an EventQueue
