用Java语言对QQ进行终极山寨---晴儿QQ诞生记之正在登录界面 QQJavaSwingJDKSUN

         今天星期六，呵呵~难得有一天的清闲，那就让我们继续我们的QQ终极逆向吧！前面几章我们已经成功的实现了一个登录界面，登陆界面完成后就是正在登录界面了，上午花了一上午的时间，终于弄出了一种大致的效果出来，还是老规矩，效果图如下：  
         
         正在登录界面我采用了完全绘制的办法直接绘制出圆角矩形JPanel，然后就是添加其中组件，我采用了GroupLayout组布局，实现了把我需要的组件添加到界面上，代码如下：
         

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.RenderingHints;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.GroupLayout;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.GroupLayout.Alignment;
import com.componentListener.WinEventAdapter;
import com.sun.awt.AWTUtilities;
import com.uiutil.UIUtil;
public class LoginingFrame{

            通过以上代码，我们基本完成了正在登录界面，正在登录界面完成之后就是聊天软件主界面了，好吧，从下一章开始我们一起开始聊天主界面的完成吧！
