Pluggable Look-and-Feel

One of the unique features of Swing is its pluggable look-and-feel (PLAF) architec-

tur e, which allows a Swing application to change its entire appearance with one or

two lines of code. The most common use of this feature is to give applications a

choice between the native platform look-and-feel and a new platform-independent

Java look-and-feel (also known as the Metal look-and-feel). Swing is distributed

with three look-and-feels: Metal and two look-and-feels that mimic the appearance

and behavior of the Windows and Motif (Unix/X) component toolkits. A look-and-

feel that mimics the Macintosh platform is available as a separate download. While

the Metal and Motif look-and-feels can be freely used, the Windows look-and-feel

is restricted for use only on Windows platform—for copyright reasons, it does not

run on any other operating system.

When a Swing application starts up, it reads the system property

swing.default-

laf to determine the classname of the default look-and-feel. In most Java ...
