今天自己写个小程序碰到了这个问题,在网上搜了一下人家的思路,整理了一下代码可以运行,感觉不错! 直接在JBuilder中新建一个应用程序,至于具体步骤就不描述了,此代码没有main函数无法直接运行。下面我贴出在Frame1中的代码: import java.awt.*; import java.awt.event.*; import javax.swing.*; import com.borland.jbcl.layout.*; import java.util.Date; 
public class Frame1     extends JFrame {   JPanel contentPane;   BorderLayout borderLayout1 = new BorderLayout();   JPanel jPanel1 = new JPanel();   XYLayout xYLayout1 = new XYLayout();   JScrollPane jScrollPane1 = new JScrollPane();   JList jList1 = new JList();  //初始化的JList中的数据   String[] strData = {       "One", "Tow", "Three"};  //保存点击按钮的时间   long clickTime = 0; 
  //Construct the frame   public Frame1() {     enableEvents(AWTEvent.WINDOW_EVENT_MASK);     try {       jbInit();     }     catch (Exception e) {       e.printStackTrace();     }   } 
  //Component initialization   private void jbInit() throws Exception {     contentPane = (JPanel)this.getContentPane();     contentPane.setLayout(borderLayout1);     this.setSize(new Dimension(532, 468));     this.setTitle("Frame Title"); 
    jPanel1.setLayout(xYLayout1);     jList1.addMouseListener(new Frame1_jList1_mouseAdapter(this));     contentPane.add(jPanel1, BorderLayout.CENTER);     jPanel1.add(jScrollPane1, new XYConstraints(18, 34, 209, 326));     jScrollPane1.getViewport().add(jList1, null);     jList1.setListData(strData);   } 
  //Overridden so we can exit when window is closed   protected void processWindowEvent(WindowEvent e) {     super.processWindowEvent(e);     if (e.getID() == WindowEvent.WINDOW_CLOSING) {       System.exit(0);     }   } 
//具体实现按钮双击的功能的方法,  很简单的算法,不做解释了 public boolean checkClickTime() {     long nowTime = (new Date()).getTime();
      if ( (nowTime - clickTime) < 300) {       clickTime = nowTime;       return true;     }     clickTime = nowTime;     return false; 
  } 
  void jList1_mouseReleased(MouseEvent e) {     //判断是否双击,是的话写你要实现的功能      if (checkClickTime()) {       System.out.println("Click Double"); 
    }   } } 
class Frame1_jList1_mouseAdapter     extends java.awt.event.MouseAdapter {   Frame1 adaptee; 
  Frame1_jList1_mouseAdapter(Frame1 adaptee) {     this.adaptee = adaptee;   } 
  public void mouseReleased(MouseEvent e) {     adaptee.jList1_mouseReleased(e);   } }
