1�Q�可以直接在�E�序中调用下面三个中的一个：
import javax.swing.*;
UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel") ;
UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel") ;
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel") ;
2�Q�或采用菜单来变换：
import javax.swing.*;
JMenuBar mb = new JMenuBar();
JMenu file = new JMenu("Look & Feel", true);
ButtonGroup buttonGroup = new ButtonGroup();
final UIManager.LookAndFeelInfo[] info = UIManager.getInstalledLookAndFeels();
for (int i = 0; i < info.length; i++) {
JRadioButtonMenuItem item = new
JRadioButtonMenuItem(info[i].getName(), i == 0);
final String className = info[i].getClassName();
item.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
try { UIManager.setLookAndFeel(className); }
catch (Exception e) { System.out.println(e); }
SwingUtilities.updateComponentTreeUI(TouchyFeely.this); }
});
buttonGroup.add(item);
file.add(item);
}
mb.add(file);
setJMenuBar(mb);
}
