Loading HTML Documents as a StyledDocument into a JEditorPane

The JEditorPane class provides the ability to display and edit multiple-attributed text.

   <source lang="java">

import java.awt.BorderLayout; import java.io.FileReader; import javax.swing.JEditorPane; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.text.html.HTMLEditorKit; public class LoadingHTMLDocuments {

 public static void main(String args[])throws Exception {
   JFrame frame = new JFrame("Tab Attributes");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   JEditorPane editorPane = new JEditorPane();
   editorPane.setEditorKit(new HTMLEditorKit());
   
   String filename = "yourFile.htm";
   
   FileReader reader = new FileReader(filename);
   editorPane.read(reader, filename);
   JScrollPane scrollPane = new JScrollPane(editorPane);
   frame.add(scrollPane, BorderLayout.CENTER);
   frame.setSize(300, 150);
   frame.setVisible(true);
 }

}</source>

Loading Web Page To JEditorPane

   <source lang="java">

import java.net.URL; import javax.swing.JEditorPane; import javax.swing.JFrame; import javax.swing.JScrollPane; public class LoadingWebPageToJEditorPane {

 public static void main(String[] a)throws Exception {
   JFrame frame = new JFrame();
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   JEditorPane editorPane = new JEditorPane();
   editorPane.setPage(new URL("http://www.jexp.ru"));
   frame.add(new JScrollPane(editorPane));
   frame.setSize(300, 200);
   frame.setVisible(true);
 }

}</source>

Show html

   <source lang="java">

import javax.swing.JEditorPane; import javax.swing.JFrame; import javax.swing.JScrollPane; public class Main {

 public static void main(String[] args) throws Exception {
   JEditorPane editor = new JEditorPane("text/html",

"

blue

");

   editor.setEditable(false);
   JScrollPane pane = new JScrollPane(editor);
   JFrame f = new JFrame("HTML Demo");
   f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   f.getContentPane().add(pane);
   f.setSize(800, 600);
   f.setVisible(true);

Using Actions with Text Components: JEditorPane

   <source lang="java">

import java.util.Arrays; import java.util.ruparator; import javax.swing.Action; import javax.swing.JEditorPane; import javax.swing.text.JTextComponent; public class ListActionsJEditorPane {

 public static void main(String args[]) {
   JTextComponent component = new JEditorPane();
   // Process action list
   Action actions[] = component.getActions();
   // Define comparator to sort actions
   Comparator<Action> comparator = new Comparator<Action>() {
     public int compare(Action a1, Action a2) {
       String firstName = (String) a1.getValue(Action.NAME);
       String secondName = (String) a2.getValue(Action.NAME);
       return firstName.rupareTo(secondName);
     }
   };
   Arrays.sort(actions, comparator);
   int count = actions.length;
   System.out.println("Count: " + count);
   for (int i = 0; i < count; i++) {
     System.out.printf("%28s : %s\n",actions[i].getValue(Action.NAME),actions[i].getClass().getName());
   }
 }
