我写了一个简单的测试类来测试seaglass外观和感觉http://seaglass.googlecode.com/的功能,我得到了'找不到nimbus类'的例外。
import java.awt.*;
import javax.swing.*;
public class asd {
private static void createWindow() throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException {
//Create and set up the window.
JFrame frame = new JFrame("Simple GUI");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel textLabel = new JLabel("I'm a label in the window",SwingConstants.CENTER);
textLabel.setPreferredSize(new Dimension(300, 100));
frame.getContentPane().add(textLabel, BorderLayout.CENTER);
//Display the window.
frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
try {
UIManager.setLookAndFeel("com.seaglasslookandfeel.SeaGlassLookAndFeel");
createWindow();
} 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();
} catch (UnsupportedLookAndFeelException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
例外

答案 0 :(得分:5)
直到Java 6更新10才包含Nimbus,所以在此之前的任何内容都不会在该位置看到该类。
引自:http://download.oracle.com/javase/tutorial/uiswing/lookandfeel/nimbus.html
对于Java SE 6 Update 10发行版, Nimbus包位于 com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel。
