简单的界面换肤术

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：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);

}
