Graphic Java 2: Mastering the Jfc, By Geary, 3Rd Edition, Volume 2: Swing

The previous chapter showed how easy it is to create some impressive programs with Swing components. Now it's time to dig in a little deeper. We begin this chapter by presenting an overview of a few key (but lower-level) helper classes such as Action, GraphicsContext, ChangeEvent, and PropertyChangeEvent, as well as the HeadlessException exception. We spend the remainder of the chapter introducing the JComponent class, the heart and soul of all Swing components.
