All Implemented Interfaces:

ActionListener, AWTEventListener

class InactivityListener
extends Object

A class that monitors inactivity in an application. It does this by using a Swing Timer and by listening for specified AWT events. When an event is received the Timer is restarted. If no event is received during the specified time interval then the timer will fire and invoke the specified Action. When creating the listener the inactivity interval is specified in minutes. However, once the listener has been created you can reset this value in milliseconds if you need to. Some common event masks have be defined with the class: KEY_EVENTS MOUSE_EVENTS - which includes mouse motion events USER_EVENTS - includes KEY_EVENTS and MOUSE_EVENT (this is the default) The inactivity interval and event mask can be changed at any time, however, they will not become effective until you stop and start the listener.
