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

DEMO

 
package com.star.update.lunach;
 
import javax.swing.JFileChooser;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
 
public class Test {
 
 public static void main(String[] args) {
 
  System.out.println(getJBossHomeByCHoose());
 }
 
 public static String getJBossHomeByCHoose() {
  initUIManager();
  JFileChooser fileChooser = new JFileChooser("d:");
  fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
  int returnVal = fileChooser.showOpenDialog(fileChooser);
  if (returnVal == JFileChooser.APPROVE_OPTION) {
   return fileChooser.getSelectedFile().getAbsolutePath();
  }
  return null;
 }
 
 private static void initUIManager() {
  String lookAndFeel = UIManager.getSystemLookAndFeelClassName();
  try {
   UIManager.setLookAndFeel(lookAndFeel);
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
  } catch (InstantiationException e) {
   e.printStackTrace();
  } catch (IllegalAccessException e) {
   e.printStackTrace();
  } catch (UnsupportedLookAndFeelException e) {
   e.printStackTrace();
  }
 }
}
