Java Foundation Classes in a Nutshell

CHAPTER 28

Thejavax.swing.plaf Package

This package contains classes and interfaces used in the definition of a pluggable

look-and-feel (hence the acronym “plaf”). It defines abstract UI delegate classes for

Swing components. Typically, only look-and-feel developers and advanced com-

ponent developers need to use this package. Figure 28-1 shows the class hierarchy

of this package. See Chapter 3, Swing Programming Topics, for further discussion

of Swing’s pluggable look-and-feel architectur e.

The javax.swing .plaf.basic package contains classes that extend the UI delegate

classes of this package to create a basic pluggable look-and-feel UI framework.

The classes in javax.swing .plaf.metal extend the classes of javax.swing .plaf.basic to

implement the default Java look-and-feel. The classes in javax.swing .plaf.multi also

extend the abstract classes of javax.swing .plaf to produce a multiplexing look-and-

feel that combines a primary look-and-feel with one or more auxiliary look-and-

feel implementations. These various subpackages of javax.swing .plaf ar e not docu-

mented in this book because they are very infrequently used and because they are

straightforward implementations of the classes in this package that do not define

any new public APIs.
