Intermediate Java(36) – loadCrap

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;

import javax.swing.event.*;

public class Read extends JFrame{

private JTextField addressBar;

private JEditorPane display;

//constructor

public Read(){

super("New Browser");

addressBar = new JTextField("enter a URL!");

addressBar.addActionListener(

new ActionListener(){

public void actionPerformed(ActionEvent event){

loadCrap(event.getActionCommand());

}

}

);

add(addressBar, BorderLayout.NORTH);

display = new JEditorPane();

display.setEditable(false);

display.addHyperlinkListener(

new HyperlinkListener(){

public void hyperlinkUpdate(HyperlinkEvent event){

if(event.getEventType()==HyperlinkEvent.EventType.ACTIVATED){

loadCrap(event.getURL().toString());

}

}

}

);

add(new JScrollPane(display),BorderLayout.CENTER);

setSize(500,300);

setVisible(true);

}

//加載在屏幕上顯示

private void loadCrap(String userText){

try{

display.setPage(userText); → setPage是從將URL的所有內容到display

addressBar.setText(userText);

}catch(Exception e){

System.out.println("Error!");

}

}

}

創建主類稱為ReadMain.java:

import javax.swing.JFrame;

public class ReadMain {

public static void main(String[] args) {

Read dude = new Read();

dude.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

}
