Java JFrame设计及最小化到系统托盘的实现

Java JFrame可以实现本地实例化窗口，通过向JFrame添加各种控件，实现各种相应的功能。

一、创建窗口实例

JFrame myFrame = new JFrame();

二、设置JFrame的各种属性

myFrame.setLayout(new BorderLayout()); ---设置窗口中组件的排列方式

myFrame.setTitle("窗口标题"); --设置窗口的标题

myFrame.setLocation(x,y); --设置窗口的显示位置

myFrame.setSize(x,y);设置窗口大小

三、实例

package monitorServer.control;

import java.awt.AWTException;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.MenuItem;
import java.awt.Panel;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.TextArea;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.IOException;
import java.net.ServerSocket;
import java.text.SimpleDateFormat;
import java.util.Date;
