SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Consumer/Listener interface for receiving POS keyboard events from the terminal workstation. An event is fired whenever a function key or data key is pressed on the POS keyboard.
WARNING: This is a synchronous call which allows keyboard events to be consumed if the listener returns a value of "true". As a result, the POS sales application is blocked waiting until the listener event processing completes. For best performance it is recommended that any lengthy event processing (e.g. GUI updates) be performed after a Thread context switch. SwingUtilities.invokeLater() may be used for this purpose.
