Having given you a taste of how event handling works, we finish this chapter with an overview of the AWT event handling architecture. As we briefly mentioned earlier, event handling in Java is object oriented, with all events descending from the EventObject class in the java. The common superclass is not called Event because that is the name of the event class in the old event model. Although the old model is now deprecated, its classes are still a part of the Java library. The event objects encapsulate information about the event that the event source communicates to its listeners. When necessary, you can then analyze the event objects that passed lake elsinore mx simulator 2013 the listener object, as we did in the button example with the getSource and get Action Command methods. Some of the AWT event classes are of no practical use for the Awt class hierarchy pdf programmer. For awt class hierarchy pdf, the AWT inserts Paint Event objects into the event queue, but these objects are not delivered to listeners.
