CommentĪs you learn about Swing youll discover: Comment There are numerous (rather thick) books dedicated solely to Swing and youll want to go to those if you need more depth, or if you want to modify the default Swing behavior.
Because of the simplicity of the Swing design, this will often be enough information to solve your problem.

I assume here that you have downloaded and installed the (free) Java library documents in HTML format from and will browse the javax.swing classes in that documentation to see the full details and methods of the Swing library. If you need to do more, then Swing can probably give you what you want if youre willing to do the research. The Swing library is vast, and the goal of this chapter is only to get you started with the essentials and comfortable with the concepts. What you see here is intended to be simple. Please be aware that this is not a comprehensive glossary of either all the Swing components, or all the methods for the described classes.
Almost all the GUI examples in this book will be executable as either applets or applications.

a regular application using Swing, and how to create programs that are both applets and applications so they can be run either inside a browser or from the command line. CommentĮarly in this chapter, youll see how things are different when you want to create an applet vs.

If for some reason you need to use the original old AWT (because youre supporting old code or you have browser limitations), you can find that introduction in the first edition of this book, downloadable at (also included on the CD ROM bound with this book). This chapter does not cover anything but the modern, Java 2 Swing library, and makes the reasonable assumption that Swing is the final destination GUI library for Java.

The revision 3 rule of the software industry (a product isnt good until revision 3) seems to hold true with programming languages as well.
Java 2 finishes the transformation away from the old Java 1.0 AWT by essentially replacing everything with the Java Foundation Classes (JFC), the GUI portion of which is called Swing. These are a rich set of easy-to-use, easy-to-understand JavaBeans that can be dragged and dropped (as well as hand programmed) to create a GUI that you can (finally) be satisfied with. The situation improved with the Java 1.1 AWT event model, which takes a much clearer, object-oriented approach, along with the addition of JavaBeans, a component programming model that is oriented toward the easy creation of visual programming environments. Certainly a marvel of productivity, and also an object lesson in why design is important. A student in one of my seminars (who had been at Sun during the creation of Java) explained why: the original AWT had been conceptualized, designed, and implemented in a month. The Java 1.0 AWT programming model is also awkward and non-object-oriented. In addition, its restrictive: you can use only four fonts and you cannot access any of the more sophisticated GUI elements that exist in your operating system. Instead, the Java 1.0 Abstract Window Toolkit (AWT) produces a GUI that looks equally mediocre on all systems. The original design goal of the graphical user interface (GUI) library in Java 1.0 was to allow the programmer to build a GUI that looks good on all platforms.
