给大家介绍两种很好玩的Look And Feel:

NapkinLookAndFeel和LiquidLookAndFeel.

效果图分别如下

NapkinLookAndFeel

LiquidLookAndFeel

测试代码如下：

DemoGui.java

import java.awt.BorderLayout; import java.io.UnsupportedEncodingException; import javax.swing.JButton; import javax.swing.JCheckBox; import javax.swing.JComboBox; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JPanel; import javax.swing.JRootPane; import javax.swing.JToggleButton; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; import net.sourceforge.napkinlaf.NapkinLookAndFeel; public class DemoGui extends JFrame { private JPanel pane = new JPanel( new BorderLayout() ); private JPanel panel1 = new JPanel(); private JPanel panel2 = new JPanel(); private JButton button; private JComboBox combox = new JComboBox(); private JCheckBox jcb = new JCheckBox(); private JMenuBar menuBar = new JMenuBar(); private JMenu menu = new JMenu( "File" ); private JMenuItem mi1 = new JMenuItem( "拷贝" ); private JMenuItem mi2 = new JMenuItem( "Cut" ); private JMenuItem mi3 = new JMenuItem( "Paste" ); private JToggleButton jtb = new JToggleButton( "Button1" ); private JToggleButton jtb1 = new JToggleButton( "Button2" ); private JToggleButton jtb2 = new JToggleButton( "Button3" ); private JToggleButton jtb3 = new JToggleButton( "暗流" ); /*private JToggleButton jtb = new JToggleButton( "<html>暗流</html>" ); private JToggleButton jtb1 = new JToggleButton( "<html>暗流</html>" ); private JToggleButton jtb2 = new JToggleButton( "<html>暗流</html>" ); private JToggleButton jtb3 = new JToggleButton( "<html>暗流</html>" );*/ static { try { UIManager.setLookAndFeel( "com.birosoft.liquid.LiquidLookAndFeel" ); //UIManager.setLookAndFeel( new NapkinLookAndFeel() ); } catch (UnsupportedLookAndFeelException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InstantiationException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public DemoGui() { try { button = new JButton( new String( "Button".getBytes( "ISO-8859-1" )) ); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } mi1.setMnemonic( 'd' ); menu.add( mi1 ); menu.add( mi2 ); menu.add( mi3 ); menuBar.add( menu ); menuBar.add( jtb1 ); menuBar.add( jtb2 ); menuBar.add( jtb3 ); panel1.add( button ); panel1.add( jcb ); panel1.add( combox ); panel1.add( jtb ); pane.add( panel1, BorderLayout.PAGE_START ); pane.add( panel2, BorderLayout.PAGE_END ); this.setJMenuBar( menuBar ); this.setContentPane( pane ); //this.setUndecorated( true ); //this.getRootPane().setWindowDecorationStyle( JRootPane.FRAME ); this.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); this.setBounds( 300, 300, 600, 400 ); this.setVisible( true ); } public static void main( String[] args ) { new DemoGui(); }} 大家看到NapkinLookAndFeel那个图里面有乱码，那是因为NapkinLookAndFeel不支持中文，比较遗憾，我猜想很可能是他使用的字体不支持中文。不过有一种很恶心的方式可以让他支持中文：那就是在所有使用中文的地方都采用html，比如： Private JButton button = new JButton( “ < html > 暗流 </ html > ” ); 不过这样button的字体就不是Napkin的风格了,大家可以试下。还有代码中有这样两行： this .setUndecorated( true ); this .getRootPane().setWindowDecorationStyle( JRootPane.FRAME ); 这两行的作用是：不使用默认的decoration,而使用你使用的LookAndFeel类提供的Decoration, 不过不是所有的LookAndFeel都提供decoration, 比如NapkinLookAndFeel就不提供，而LiquidLookAndFeel里面就提供，大家可以把这两行取消注释试一下。还有一点提醒大家注意，我的测试代码里把 UIManager.setLookAndFeel( " com.birosoft.liquid.LiquidLookAndFeel " ); // UIManager.setLookAndFeel( new NapkinLookAndFeel() ); 放在static初始化块里面了，这不是必须的，但是你必须保证把这段代码放在你生成所有的Component/Jcomponent之前，否则LookAndFeel不能生效。参考资料： Napkin和Liquid都可以在sourceforge上找的到。
