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
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{/**阐述：该文件定义了晴儿QQ即时通软件的正在登录界面 * 作者：陈阳(JavaEye博客：http://chen6485.iteye.com/) * 说明：开发环境：MyEclipse6.6 JDK版本:Java(TM)SE Development Kit 6 Update 22 */public LoginFrame u;private static final long serialVersionUID = -3291651336702369751L;private JDialog Logining=new JDialog();private LoginPanel panel=new LoginPanel();private ImageIcon cancel_normal=new ImageIcon(this.getClass().getResource("../image/SysButton/cancel_normal.png"));private ImageIcon cancel_rollover=new ImageIcon(this.getClass().getResource("../image/SysButton/cancel_rollover.png"));private ImageIcon cancel_press=new ImageIcon(this.getClass().getResource("../image/SysButton/cancel_pressed.png"));private ImageIcon pic_login=new ImageIcon(this.getClass().getResource("../image/logining.gif"));//正在登录图片private ImageIcon title=new ImageIcon(this.getClass().getResource("../image/title1.png"));//QQ标题private ImageIcon top=new ImageIcon(this.getClass().getResource("../image/top.png"));//QQ标题栏private Image titleImage=title.getImage();private Image topImage=top.getImage();private JLabel lab_pic=new JLabel(pic_login);private JLabel lab_account=new JLabel();//正在登录的账号标签private JLabel lab_welcome=new JLabel("尊敬的晴儿QQ用户，欢迎你回来");//欢迎登录标签private JButton cancel=UIUtil.creatButton(cancel_normal, cancel_rollover, cancel_press);private WinEventAdapter winMove=new WinEventAdapter(Logining);//注册移动位置监听;public LoginingFrame(){initComponent();init();}public void init(){Logining.setUndecorated(true);Logining.setContentPane(panel);AWTUtilities.setWindowOpaque(Logining, false);Logining.setSize(239,535);Logining.setVisible(true);Logining.addMouseListener(winMove);Logining.addMouseMotionListener(winMove);Logining.getRootPane().setDefaultButton(cancel);}public void initComponent(){lab_account.setText(u.name);GroupLayout gro=new GroupLayout(panel);//实例化布局方式panel.setLayout(gro);gro.setAutoCreateGaps(true);gro.setAutoCreateContainerGaps(true);GroupLayout.SequentialGroup xgroup = gro.createSequentialGroup();xgroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addComponent(lab_pic).addComponent(lab_account).addComponent(lab_welcome).addComponent(cancel)); gro.setHorizontalGroup(xgroup);//添加平行放置的组件GroupLayout.SequentialGroup ygroup=gro.createSequentialGroup();ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addGap(90));ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addComponent(lab_pic));ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addComponent(lab_account));ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addComponent(lab_welcome));ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addGap(50));ygroup.addGroup(gro.createParallelGroup(Alignment.CENTER).addComponent(cancel));gro.setVerticalGroup(ygroup);//添加垂直放置的组件cancel.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e){stopLogin();}});}public void stopLogin(){System.exit(0);}private class LoginPanel extends JPanel{private static final long serialVersionUID=-72456689714251903L;protected void paintComponent(Graphics g){super.paintComponent(g);Graphics2D g2 =(Graphics2D)g;g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);//使用抗锯齿g2.setColor(new Color(214,238,255));g2.fillRoundRect(0,0,Logining.getWidth(),Logining.getHeight(),8,8);//用上面的颜色绘制填充整个JDialogg2.setColor(new Color(0,81,149));g2.drawRoundRect(0,0, Logining.getWidth()-1, Logining.getHeight()-1, 8,8);//用上面的颜色绘制填充最外层的边缘g2.setColor(new Color(158,249,255));g2.drawRoundRect(1, 1, Logining.getWidth()-3, Logining.getHeight()-3,8,8);//用上面的颜色绘制填充第二个外边缘g2.drawImage(topImage, 1, 1, Logining.getWidth()-2, 27, null);g2.drawImage(titleImage,3,4,null);}} }

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！
