Foil 37 Delegation Event Model

From Tutorial on Scivis Java Visualization System Rome Lab CIV Review, NAVO Miss. Tutorial -- Sept 24-25 97. by Byeongseob Ki, Scott KLasky


The new event handling model:
  • Components fire events, which can be listened for and acted upon by listeners.
  • Listeners are added to a component.
  • After being added to a component, appropriate methods in the listener's interface will be called when the events the listener has registered interested in are fired by the component.
  • Whenever an event occurs, we have to handle it to be collaborative. But we only need to add codes to the listener by using delegation event model of JDK1.1.
