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Frame中的代码
import javaawt*;
import javaawtevent*;
import javaxswing*;
import comborlandjbcllayout*;
import javautilDate;
public class Frame
extends JFrame {
JPanel contentPane;
BorderLayout borderLayout = new BorderLayout();
JPanel jPanel = new JPanel();
XYLayout xYLayout = new XYLayout();
JScrollPane jScrollPane = new JScrollPane();
JList jList = 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 = ;
//Construct the frame
public Frame() {
enableEvents(AWTEventWINDOW_EVENT_MASK);
try {
jbInit();
}
catch (Exception e) {
eprintStackTrace();
}
}
//Component initialization
private void jbInit() throws Exception {
contentPane = (JPanel)thisgetContentPane();
contentPanesetLayout(borderLayout);
thissetSize(new Dimension( ));
thissetTitle(Frame Title);
jPanelsetLayout(xYLayout);
jListaddMouseListener(new Frame_jList_mouseAdapter(this));
contentPaneadd(jPanel BorderLayoutCENTER);
jPaneladd(jScrollPane new XYConstraints( ));
jScrollPanegetViewport()add(jList null);
jListsetListData(strData);
}
//Overridden so we can exit when window is closed
protected void processWindowEvent(WindowEvent e) {
superprocessWindowEvent(e);
if (egetID() == WindowEventWINDOW_CLOSING) {
Systemexit();
}
}
//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) < ) {
clickTime = nowTime;
return true;
}
clickTime = nowTime;
return false;
}
void jList_mouseReleased(MouseEvent e) {
//判断是否双击是的话写你要实现的功能
if (checkClickTime()) {
Systemoutprintln(Click Double);
}
}
}
class Frame_jList_mouseAdapter
extends javaawteventMouseAdapter {
Frame adaptee;
Frame_jList_mouseAdapter(Frame adaptee) {
thisadaptee = adaptee;
}
public void mouseReleased(MouseEvent e) {
adapteejList_mouseReleased(e);
}
}
