hi friends,
I have done many things in Java (only basics). I have never heard about the Look and Feel of Nimbus.!! I have been told to change the look and feel to nimbus. Really speaking, I have never heard about the Nimbus look and feel. So guys, please tell me how to use Nimbus Look and Feel? Any more information related to the same topic would be grateful.!!!

Have you heard about the looks and feels about the application in Java..?? I think that you must know more about that first, then you can check with the Nimbus looks and feels. The architecture of Swing is designed so that you may change the "look and feel" of your application's GUI. You can also set the Look and Feel programatically. Also the looks and feels can be specified by Command Line or the swing.properties File. Hope that you got some good points from this.!!

You can also change the look and feel after startup, for which you would have to use the setLookAndFeel. In simple words, you can change the looks and feels with setLookAndFeel even after the program's GUI is visible. You will have to invoke the SwingUtilities updateComponentTreeUI method once per top-level container for making existing components reflect the new looks and feels. You can check the following example :

UIManager.setLookAndFeel(lnfName);
SwingUtilities.updateComponentTreeUI(frame);
frame.pack();

I think that you should know about the look and feels in Java which is used for the applications. The good thing about the Nimbus is that, you can use the Nimbus look and feel as is, or you can customize, by giving look of your own brand. That's why the Nimbus is highly customizable. Also I would like to alert you with the following thing which happened in my case, so you must be aware of that. "Do not set the Nimbus look and feel explicitly by invoking the UIManager.setLookAndFeel method because not all versions or implementations of Java SE 6 support Nimbus".

When you don't change the setting of the look and feel, Metal will be the default Swing look and feel. If you want it in Nimbus look and feel, then you will have to put some coding for that. I am giving the code that you would have to add to the event-dispatching thread before creating the graphical user interface :

import javax.swing.UIManager.*;

try {
    for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
        if ("Nimbus".equals(info.getName())) {
            UIManager.setLookAndFeel(info.getClassName());
            break;
        }
    }
} catch (Exception e) {

}

If you want to set the default look and feel to Nimbus permanently, you can do this by adding following line to the <JAVA_HOME>/lib/swing.properties file. If the swing.properties file is not existing, then you will have to create it before using the following line :

swing.defaultlaf=javax.swing.plaf.nimbus.NimbusLookAndFeel
