java UIManager的风格【Z】

Java'中的几种Look and Feel
1、Metal风格 (默认)
String lookAndFeel = "javax.swing.plaf.metal.MetalLookAndFeel";
UIManager.setLookAndFeel(lookAndFeel);
2、Windows风格
String lookAndFeel = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
UIManager.setLookAndFeel(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)方法立刻更新应用的外观
这两个类均在javax.swing包中

public
 
void
 actionPerformed(ActionEvent e) {
String lnfName = null
;
if
 (e.getActionCommand().equals(
"Metal"
)) {
    lnfName = "javax.swing.plaf.metal.MetalLookAndFeel"
;
 } else
 
if
 (e.getActionCommand().equals(
"Motif"
)) {
   lnfName = "com.sun.java.swing.plaf.motif.MotifLookAndFeel"
;
} else
 {
    lnfName = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel"
;
}
try
 {
    UIManager.setLookAndFeel(lnfName);
    SwingUtilities.updateComponentTreeUI(frame);
} catch
 (UnsupportedLookAndFeelException ex1) {
    System.err.println("Unsupported LookAndFeel: "
 + lnfName);
} catch
 (ClassNotFoundException ex2) {
    System.err.println("LookAndFeel class not found: "
 + lnfName);
} catch
 (InstantiationException ex3) {
    System.err.println("Could not load LookAndFeel: "
 + );
} catch
 (IllegalAccessException ex4) {
    System.err.println("Cannot use LookAndFeel: "
 + lnfName);
}
}

public void actionPerformed(ActionEvent e) {
String lnfName = null;
if (e.getActionCommand().equals("Metal")) {
    lnfName = "javax.swing.plaf.metal.MetalLookAndFeel";
 } else if (e.getActionCommand().equals("Motif")) {
   lnfName = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
} else {
    lnfName = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
}
try {
    UIManager.setLookAndFeel(lnfName);
    SwingUtilities.updateComponentTreeUI(frame);
} catch (UnsupportedLookAndFeelException ex1) {
    System.err.println("Unsupported LookAndFeel: " + lnfName);
} catch (ClassNotFoundException ex2) {
    System.err.println("LookAndFeel class not found: " + lnfName);
} catch (InstantiationException ex3) {
    System.err.println("Could not load LookAndFeel: " + );
} catch (IllegalAccessException ex4) {
    System.err.println("Cannot use LookAndFeel: " + lnfName);
}
}
