Java实现带有滚动效果的标签

有时候，我们需要使得标签效果更加美观好看一点，可以使用滚动效果的标签；应用时，将JLabel换成MoveLabel类来定义，如

                   MoveLabel label = new MoveLabel（“测试”）；

其中，MoveLabel类的定义实现如下，直接复制到class中即可：

 /**
  * 带有滚动效果的Label标签，可设置颜色变换、速度变换等
  */
 private class MoveLabel extends JLabel implements Runnable {

  private static final long serialVersionUID = 1891684760189602720L;

  private String text = null;

  private Thread thread = null;

  private int x = 0;

  private int w = 0, h = 0;

  public MoveLabel(String text) {
   super(text);
   this.text = text;
   thread = new Thread(this);
   thread.start();
  }

  public String getText() {
   return text;
  }

  public void setText(String text) {
   super.setText(text);
   this.text = text;
  }

  protected void paintComponent(Graphics g) {
   super.paintComponent(g);
   g.setColor(this.getBackground());
   g.fillRect(0, 0, w = this.getWidth(), h = this.getHeight());
   g.setColor(this.getForeground());
   g.setFont(this.getFont());
   g.drawString(text, x, h - 2);
  }

  public void run() {
   while (true) {
    x -= 2;
    if (x < -w) {
     x = w;
    }
    this.repaint();
    try {
     Thread.sleep(35);
    } catch (InterruptedException e) {
     e.printStackTrace();
    }
   }
  }
 }
