SEAGLASS的外觀和感覺

Question

我寫了一個簡單的測試類來測試一下SEAGLASS的功能和感覺http://seaglass.googlecode.com/和我得到的例外「靈氣類未找到」。

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(); 
      } 



    } 
}

Answer 1

雨雲沒有被列入到了Java 6 Update 10的，所以任何事情之前，不會看到類在該位置。

對於Java SE 6更新10釋放， 雨雲包位於 com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel。
