【JAVA】 UIMnager

Java'中的几种Look and Feel 1、Metal风格 (默认) String lookAndFeel = "javax.swing.plaf.metal.MetalLookAndFeel"; UIManager.setLookAndFee(lookAndFeel);

2、Windows风格 String lookAndFeel = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel"; UIManager.setLookAndFee

(lookAndFeel);   3、Windows Classic风格 String lookAndFeel = "com.sun.java.swing.plaf.windows.WindowsClassicLookAndFeel";

UIManager.setLookAndFeel(lookAndFeel);

4、Motif风格 String lookAndFeel = "com.sun.java.swing.plaf.motif.MotifLookAndFeel"; UIManager.setLookAndFeel(lookAndFeel);

5、Mac风格 (需要在相关的操作系统上方可实现) String lookAndFeel = "com.sun.java.swing.plaf.mac.MacLookAndFeel";

UIManager.setLookAndFeel(lookAndFeel);

6、GTK风格 (需要在相关的操作系统上方可实现) String lookAndFeel = "com.sun.java.swing.plaf.gtk.GTKLookAndFeel";

UIManager.setLookAndFeel(lookAndFeel);

7、可跨平台的默认风格 String lookAndFeel = UIManager.getCrossPlatformLookAndFeelClassName(); UIManager.setLookAndFeel

(lookAndFeel);

8、当前系统的风格 String lookAndFeel = UIManager.getSystemLookAndFeelClassName(); UIManager.setLookAndFeel(lookAndFeel);

在Java中让用户能够动态地更改应用的外观，可以给用户更好地体验，具体的实现方式是： 1，先使用UIManager.setLookAndFeel(String s)方法设

定对应的外观 2，再使用SwingUtilities.updateComponentTreeUI(Component c)方法立刻更新应用
