回到当前日期是有的,就是点击最下面的"今天:2007年08月29日"就回到当前的日期了至于加一个上一年和下一年,我当前也考虑了,加了两个按钮好像就很容易按错了 ...

不会啊，使用GridBagLayout布局，挺好的，给你改了一下，加了上一年和下一年，呵呵

有个问题，就是那个setToolTipText()在这里没用，运行时当鼠标移到上面的时候不显示提示信息，不知道怎么回事
程序代码：
private class JP1 extends JPanel{

//super(new BorderLayout());
this.setBackground(new Color(160,185,215));
initJP1();
}
private void initJP1(){
lastYear=new JLabel(" << ",JLabel.CENTER);
nextYear=new JLabel(" >> ",JLabel.CENTER);
lastYear.setToolTipText("上一年");
nextYear.setToolTipText("下一年");
lastMonth=new JLabel(" < ",JLabel.CENTER);
lastMonth.setToolTipText("上一月");
nextMonth=new JLabel(" > ",JLabel.CENTER);
nextMonth.setToolTipText("下一月");
center=new JLabel("",JLabel.CENTER);
updateDate();
GridBagLayout gridbag = new GridBagLayout();

还改了一个地方， MyLabel.mouseReleased()，改为双击时选定日期，这样更人性化一点
public void mouseReleased(MouseEvent e) {
// 双击时选定
if (e.getClickCount() == 2) {
commit();
return;
}
Point p=SwingUtilities.convertPoint(this,e.getPoint(),jp3);
lm.setSelect(p,false);
}
