Ideally as per LAF doco, if you have set the correct look and feel you should get this automatically.

UIManager.setLookAndFeel(
            UIManager.getCrossPlatformLookAndFeelClassName());

If not see what they have done here http://www.roseindia.net/java/example/java/swing/copy-data-from-ms.shtml
