动画/滚动文字

Question

我想知道如何制作滚动文字。就像可以从右侧滚动到左侧的文本一样。如何在Java GUI中动画文本？

也许不是OP的答案，但我看不到的原因，通过工具Swing Timer很简单，（可能是半透明的容器），并把那里JLabel，（更新到JLabel可能是从CharsArray到避免调整容器大小），例如

import java.awt.Color; 
import java.awt.EventQueue; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 
import javax.swing.JWindow; 
import javax.swing.Timer; 

public class SlideTextSwing { 

    private JWindow window = new JWindow(); 
    private JLabel label = new JLabel("Slide Text Swing, Slide Text Swing, .........."); 
    private JPanel windowContents = new JPanel(); 

    public SlideTextSwing() { 
     windowContents.add(label); 
     window.add(windowContents); 
     window.pack(); 
     window.setLocationRelativeTo(null); 
     final int desiredWidth = window.getWidth(); 
     window.getContentPane().setLayout(null); 
     window.setSize(0, window.getHeight()); 
     window.setVisible(true); 
     Timer timer = new Timer(20, new ActionListener() { 

      @Override 
      public void actionPerformed(ActionEvent e) { 
       int newWidth = Math.min(window.getWidth() + 1, desiredWidth); 
       window.setSize(newWidth, window.getHeight()); 
       windowContents.setLocation(newWidth - desiredWidth, 0); 
       if (newWidth >= desiredWidth) { 
        ((Timer) e.getSource()).stop(); 
        label.setForeground(Color.red); 
        mainKill(); 
       } 
      } 
     }); 
     timer.start(); 
    } 

    public void mainKill() { 
     Timer timer = new Timer(500, new ActionListener() { 

      @Override 
      public void actionPerformed(ActionEvent e) { 
       System.exit(0); 
      } 
     }); 
     timer.start(); 
    } 

    public static void main(String args[]) { 
     EventQueue.invokeLater(new Runnable() { 

      public void run() { 
       SlideTextSwing windowTest = new SlideTextSwing(); 
      } 
     }); 
    } 
}
