Hi

I search for a sample RTF Editor to study RTF editing in Java.
I found one really interesting in legacy forum java answer, at URL http://www.artima.com/legacy/answers/Feb2002/messages/153.html.

I tried to compile it but it can't find LoadRtf object.

Could someone tell me where can I find it ?

Thanks for your help.

Jean-Paul

Try the RTFReader.java code at:
http://www.quantumhyperspace.com/SourceBank/viewCode.jsp?javaFile=RTFReader.java
or the following:

/* RTFViewer.java
* March 9, 2003
*/

import java.awt.*;
import java.io.*;
import javax.swing.*;
import javax.swing.filechooser.*;
import javax.swing.text.*;
import javax.swing.text.rtf.*;


/** Constructs an RTF editor kit to display the
* contents of an RTF document in a JEditorPane.
* @author: Charles Bell
* @version March 8, 2003
*/
public class RTFViewer extends JFrame{

private RTFEditorKit kit;
private File file;
private JEditorPane editor;

/** Default constructor. */
public RTFViewer(){
super("RTF Viewer");
init();
}


/** Constructor using file object as input. */
public RTFViewer (File file){
super("RTF Viewer: " + file.getName());
this.file = file;
init();
}

/** Constructor using filename string object as input. */
public RTFViewer (String fileName){
super("RTF Viewer: " + fileName);
this.file = new File(fileName);
init();
}

/** Runs as application. */
public static void main(String[] args){
if (args.length == 0){
new RTFViewer();
}else{
new RTFViewer(args[0]);
}
}

/** Creates a default document to hold the contents of the RTF
* file, and displays its contents in a JEditorPane.
*/
public void init(){
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
try{
kit = new RTFEditorKit();
editor = new JEditorPane();
editor.setEditable(false);
kit.install(editor);
Document doc = kit.createDefaultDocument();
if (file == null) {
file = getFile();
if (file == null) {

}
}

FileInputStream fis = new FileInputStream(file);
kit.read(fis,doc,0);
editor.setText(doc.getText(0,doc.getLength()));
setSize(Toolkit.getDefaultToolkit().getScreenSize());
getContentPane().add(new JScrollPane(editor), BorderLayout.CENTER);
show();
}catch (BadLocationException ble){
System.err.println("BadLocationException: " + ble.getMessage());
}catch (IOException ioe){
System.err.println("IOException: " + ioe.getMessage());
}
}

/** Uses a JFileDialog to retrieve a file from the user.
*/
private File getFile(){
File f = null;
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new RTFFileNameFilter());
if (fileChooser.showOpenDialog(this) == JFileChooser.APPROVE_OPTION){
f = fileChooser.getSelectedFile();
}
return f;
}

/** Control exit. */

private void exit(){
System.exit(0);
}

/** For the rtf file filter.
*/
class RTFFileNameFilter extends javax.swing.filechooser.FileFilter{

public boolean accept(File file){
boolean status = false;
String filename = file.getName().toLowerCase();
return (filename.indexOf("rtf") > 0);
}

public String getDescription(){
return "RTF file";
}
}

}
