We help you choose the appropriate components for your GUI, tell you how to use them, and give you the background information you need to use them effectively. We also discuss other JFC features as they apply to Swing components.<blockquote><hr><strong>Version Note:</strong> "Swing" was the code name of the project that developed the new components. Although unofficial, it's frequently used to refer to the new components and related API. "Swing" is immortalized in the package names for the Swing API, which begin with <code>javax.swing</code>. <hr></blockquote></blockquote><H3>Which Swing Packages Should I Use?</H3><blockquote>The Swing API is powerful, flexible--and immense. In release 1.4 of the Java platform, the Swing API has 17 public packages:<blockquote><TABLE BORDER="0" CELLSPACING="2" CELLPADDING="2"WIDTH="100%"> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.accessibility</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.plaf</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.text.html</CODE></TD> </TR> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.plaf.basic</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.text.parser</CODE></TD> </TR> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.border</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.plaf.metal</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.text.rtf</CODE></TD> </TR> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.colorchooser</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.plaf.multi</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.tree</CODE></TD> </TR> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.event</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.table</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.undo</CODE></TD> </TR> <TR> <TD WIDTH="172"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.filechooser</CODE></TD> <TD WIDTH="150"> <P CLASS="TCH-Table-Column-Head1"><CODE>javax.swing.text</CODE></TD> <TD WIDTH="157"> <P CLASS="TCH-Table-Column-Head"> </TD> </TR></TABLE></blockquote>Fortunately, most programs use only a small subset of the API.
