The Metalworks system demo provided with the JDK installation (
jdk1.5.0\demo\
jfc\Metalworks
) comes with examples for customizing themes. One of the themes it defines
reads the theme color settings from a property file. Instead of needing to create a new class file
every time you want to change the theme of your Swing application, you can read it from a file
at runtime.
