Foil 48 JavaBean and JDK1.1 AWT Event Model

From Javabeans Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Nancy McCracken, Wojtek Furmanski
1 The various listeners and events are named in pairs XListener (an interface extending java.util.EventListener) and XEvent (an object extending java.util.EventObject)
2 Registration involves methods for the source called
  • public void addXListener ( XListener callbackobject)
  • public void removeXListener ( XListener callbackobject)
  • These increment or decrement an array of listeners which the source must keep
3 Such naming conventions are part of the design pattern for the JavaBean (JDK1.1) framework
4 X = Component, Focus, Key, Mouse, MouseMotion, Window, Container, Text, Action, Adjustment and Item in JDK1.1 AWT
