【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

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();
}
}
}
