Nimbus Look and Feel

Nimbus is highly customizable. You can use the Nimbus look and feel as is, or you can skin (customize) the look with your own brand.

Enabling the Nimbus Look and Feel

• Add the following code to the event-dispatching thread before creating the graphical user interface (GUI):

  import javax.swing.UIManager.*;
  
  try {
      for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
          if ("Nimbus".equals(info.getName())) {
              UIManager.setLookAndFeel(info.getClassName());
              break;
          }
      }
  } catch (Exception e) {
      // If Nimbus is not available, you can set the GUI to another look and feel.
  }
  

  The first line of code retrieves the list of all installed look and feel implementations for the platform and then iterates through the list to determine if Nimbus is available. If so, Nimbus is set as the look and feel.

  Version Note: 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. Additionally, the location of the Nimbus package changed between the JDK 6 Update 10 and JDK 7 releases. Iterating through all installed look and feel implementations is a more robust approach because if Nimbus is not available, the default look and feel is used. For the JDK 6 Update 10 release, the Nimbus package is located at com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel.

• Specify Nimbus as the default look and feel for a particular application at the command line, as follows:

  java -Dswing.defaultlaf=javax.swing.plaf.nimbus.NimbusLookAndFeel MyApp
  

• Permanently set the default look and feel to Nimbus by adding the following line to the <JAVA_HOME>/lib/swing.properties file:

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

  If the swing.properties file does not yet exist, you need to create it.
