How to implement "GTKLookAndFeel"

Hello,

I want to implement some theme on my application. I am new with swing and someone suggest me to use GTKLookAndFeel class. I try to implement it by statement :

UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAndFeel");

then it gives me error :

java.lang.ClassNotFoundException: com.sun.java.swing.plaf.gtk.GTKLookAndFeel

I inclued path of src from jdk in CLASSPATH.

I am using JDK 1.5.

Can Any body help me?

If you know source from where I can get all class file required for GTKLookAndFeel then please give it's reference to me so i can check it by replacing existing one.

Thanks in advance

Thanks kirillg for reply,

I changed my JDK and now I have latest JDK "Java SE 6 BETA 2". With this jdk I found one src folder in which GTKLookAndFeel.java is present But I didn't found GTKLookAndFeel.class.

I try to make class file but this one is related to many other files which are in complex structure and thst's why I am fail to make class file.

I am working on Windows platform.

Can you know other source from which i can get all required class files to implement GTK.

Thanks

You don't need to build this class since it's a part of JRE installation on the specific platform. However, as GtkLookAndFeel uses the underlying *native* renderer, it's not available on Windows. The same goes for WindowsLookAndFeel that uses the *native* rendering - it's not available on other platforms.
