如何用Java开发"多画面浏览器" 有没有源程序! 我只会写这些:
import java.io.IOException;
import java.net.URL;
import javax.swing.*;
import javax.swing.text.Document;
import javax.swing.text.JTextComponent;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
public class HtmlBrowser extends JFrame{
JPanel contentPane;
BorderLayout borderLayoutAll=new BorderLayout();
JLabel jLabelPrompt=new JLabel();
JPanel jPanelMain=new JPanel();
BorderLayout borderLayoutMain=new BorderLayout();
JTextField textFieldURL=new JTextField();
JEditorPane jEditorPane=new JEditorPane();
public HtmlBrowser() {
try{jbInit();
}
catch(Exception e){
e.printStackTrace();}
}
private void jbInit()throws Exception{
contentPane=(JPanel)getContentPane();
contentPane.setLayout(borderLayoutAll);
jPanelMain.setLayout(borderLayoutMain);
jLabelPrompt.setText("please enter url");
textFieldURL.setText(" ");
textFieldURL.addActionListener(new java.awt.event.ActionListener(){
public void actionPerformed(ActionEvent e)
{textFieldURL_actionPerformed(e);}
});
jEditorPane.setEditable(false);
jEditorPane.addHyperlinkListener(new javax.swing.event.HyperlinkListener()
{public void hyperlinkUpdate(HyperlinkEvent e){
jEditorPane_hyperlinkUpdate(e);}
});
JScrollPane scrollPane=new JScrollPane();
scrollPane.getViewport().add(jEditorPane);
jPanelMain.add(textFieldURL,"North");
jPanelMain.add(scrollPane,"Center");
contentPane.add(jLabelPrompt,"North");
contentPane.add(jPanelMain,"Center");
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
this.setSize(new Dimension(600,500));
this.setTitle("我的浏览器");
this.setVisible(true);
}
void textFieldURL_actionPerformed(ActionEvent e){
try{jEditorPane.setPage(textFieldURL.getText());
}
catch(IOException ex){JOptionPane msg=new JOptionPane();
JOptionPane.showMessageDialog(this,"URL地址不正确："+textFieldURL.getText(),"输入不正确 ！",0);
}
}
void jEditorPane_hyperlinkUpdate(HyperlinkEvent e)
{
if(e.getEventType ()==
javax.swing.event.HyperlinkEvent.EventType.ACTIVATED)
{
try{
URL url=e.getURL();
jEditorPane.setPage(url);
textFieldURL.setText(url.toString());}
catch(IOException io){
JOptionPane msg=new JOptionPane();
JOptionPane.showMessageDialog(this,"打开文件失败！"+textFieldURL.getText(),"输入的不正确！",0);
}
}
}
protected void processWindowEvent(WindowEvent e) {
super.processWindowEvent(e);
if (e.getID() == WindowEvent.WINDOW_CLOSING) {
System.exit(0);
}
}
public static void main(String[] args) {
new HtmlBrowser();
}
}
