Hi Kevin, Use Observer/Observable design. You may read about it in JavaDocs. The basic idea is that one object is the observable and it notifies all observers when some event occurs. Check out: Observer Interface: http://java.sun.com/j2se/1.4.1/docs/api/java/util/Observer.html Observable Class: http://java.sun.com/j2se/1.4.1/docs/api/java/util/Observable.html HTH, David Travis. ----- Original Message ----- From: "Kevin W" <null at tsn.cc> To: <thelist at lists.evolt.org> Sent: Thursday, January 09, 2003 10:05 AM Subject: [thelist] Java classes and events > Not sure if this is on topic here, but... > I've got a JFrame object "gameWindow" that creates a JPanel object "board". > board invokes and receives an ActionEvent. board processes the > ActionEvent. > > Is there any way for board to let gameWindow know about the event as well? > Or do I have to make gameWindow check continually for a board variable to > change? > > -- > Kevin W :-) > -- > * * Please support the community that supports you. * * > http://evolt.org/help_support_evolt/ > > For unsubscribe and other options, including the Tip Harvester > and archives of thelist go to: http://lists.evolt.org > Workers of the Web, evolt !
