insertHTML in a JEditorPane

[olbion]

Hi all,

I have created a JEditorPane which I use in a chat client, with the purpose of interpreting HTML and supporting links. It's working, but I believe I havn't come up with the optimal solution for inserting new html code. I store new strings in a StringBuffer, and then after each new string is appended, I update the HTML content using setText. See my code below.

Code:

package com.olof.chat;

import java.awt.Color;
import java.awt.Font;

import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
import javax.swing.JEditorPane;

import com.olof.applet.AppletActions;

public class EditorPaneHyperlinked extends JEditorPane implements HyperlinkListener
{
	private AppletActions aa;
	private StringBuffer sb;
	
	public EditorPaneHyperlinked(AppletActions aa)
	{
		setContentType("text/html");
		addHyperlinkListener(this);
		setEditable(false);
		setFocusable(true);
		this.aa = aa;
		sb = new StringBuffer();
	}
	
	public void append(String message, Font font, Color color)
	{
		String html = "<span style=\"color:#"
			+ Integer.toHexString(color.getRGB()).substring(2)
			+ "; font-family:"
			+ font.getFamily()
			+ "; font-size:"
			+ font.getSize()
			+ "pt; font-weight:"
			+ (font.getStyle() == font.BOLD ? "bold" : "")
			+ "\">"
			+ message
			+ "</span>";
		append(html);
	}
	
	public void append(String message)
	{
		System.out.println("Appending: " + message);
		sb.append(message);
		setText(sb.toString());
	}
	
	public void clear()
	{
		sb = new StringBuffer();
		setText("");
	}
	
	public void hyperlinkUpdate(HyperlinkEvent ev) {
		System.out.println("hyperlink event");
		System.out.println("type: "+ev.getEventType());
		System.out.println("url: "+ev.getURL());
		if (ev.getEventType() == HyperlinkEvent.EventType.ACTIVATED)
		{
			System.out.println("goTo: "+ev.getURL());
			//applet.goTo(ev.getURL(), "_blank");
			aa.action();
		}
	}
	
	public void newLine()
	{
		append("<br/>");
	}
}

Optimally, I believe I would use something like

Code:

doc = getDocument;
doc.insert();

However, if I do that, it does not interpret the HTML anymore. Perhaps I need to use a HTMLDocument, but how do I achieve that?

You might want to use the Cobra HTML parser, a component of the pure-Java Lobo browser. (But don't ask me for details; I'm a Lobo newbie. )
