Listening For Events With the 1.0 Model
  • So, how do we deal with the action event posted by the button? Well, as we mentioned earlier, we can listen for and handle button events in a couple of different ways.

  • The first way is to use the JDK 1.0 model. In the 1.0 model, when the OK button posts an event, the handleEvent() method of the button object is called with an object that contains information about the event. If the button doesn't handle the event, the button's parent is notified. This continues up the chain until the event reaches the top-most container.

  • Thus, in order to capture and handle the event at any stage we need to implement a handleEvent() method to catch the event the button posts.
