java 如何模仿QQ聊天框那样可以显示文字与图片啊？

package ibees.qq;

/**

public QQLoginView() {

}

private void initComponent() {

setTitle("用户登录");

//设置LOGO

URL image = QQLoginView.class.getClassLoader().getResource("ibees/qq/images/year.jpg");//图片的位置

JLabel imageLogo = new JLabel(new ImageIcon(image));

add(imageLogo,BorderLayout.NORTH);

//QQ号和密码

JPanel jp = new JPanel();

JPanel jpAccount = new JPanel();

jpAccount.add(new JLabel("帐号"));

JTextField userTextField = new JTextField(15);

jpAccount.add(userTextField);

jpAccount.add(new JLabel("用户注册"));

jp.add(jpAccount);

JPanel jpPass = new JPanel();

jpPass.add(new JLabel("密码"));

JPasswordField passTextField = new JPasswordField(15);

jpPass.add(passTextField);

jpPass.add(new JLabel("找回密码"));

jp.add(jpPass);

//登录设置

JPanel jpstatus = new JPanel();

jpstatus.add(new JLabel("状态"));

JComboBox statusComboBox = new JComboBox();

statusComboBox.addItem("Q我");

statusComboBox.addItem("在线");

statusComboBox.addItem("隐身");

statusComboBox.addItem("离线");

jpstatus.add(statusComboBox);

jpstatus.add(new JCheckBox("记住密码"));

jpstatus.add(new JCheckBox("自动登录"));

jp.add(jpstatus);

add(jp);

//底部登录按钮

JPanel bottomPanel = new JPanel();

bottomPanel.setLayout(new BorderLayout());

bottomPanel.add(new JButton("设置"),BorderLayout.WEST);

bottomPanel.add(new JButton("登录"),BorderLayout.EAST);

add(bottomPanel,BorderLayout.SOUTH);

setSize(324,230);

setDefaultCloseOperation(EXIT_ON_CLOSE);

setLocationRelativeTo(null);

}

/**

*/

public static void main(String[] args) {

java.awt.EventQueue.invokeLater(new Runnable(){

@Override

public void run() {

new QQLoginView().setVisible(true);

}

});

}

}

两种解决办法,

第一种使用纯java的方式,使用组件JTextPane 或者JEditorPane 来显示图片和文字

第二种使用JEditorPane,但是里面存放HTML代码. 用HTML来控制文字和图片的显示

给你个Socket/ServerSocket写的小例子,看看能不能帮到你哦:

先运行ServerGUI,启动服务器端,再运行ClientGUI,双方就可以发送字符串了...
