Rendering HTML in a JTextPane

Hi,

is it possible to render a String containing HTML (e.g.
<h1>News</h1><p>News text</p>) in a JTextPane showing the String as
rendered HTML?

Thanks!

Sure, it is as simple as this:

JTextPane textPane = new JTextPane();
textPane.setContentType("text/html");
textPane.setText("<h1>News</h1><p>News text</p>");

Wow, thats easy :) Now I have URLs in the TextPane... However, they are
not clickable, the mouse cursor doesn't change. It would be great just
to call the default browser and send the URL if a URL is being clicked.

Can you give me a hint?

Thanks!

I changed the JTextPane to a JEditorPane. The mouse cursor now changes
when hovering over a URL. But how can I launch a browser and direct it
to the clicked link?

Thanks!

Look for 'Hyperactive' in the sun tutorials, they implement an easy
Listener.

?? indeed.  Try this source..
<sscce>
import javax.swing.*;

public class TestContentType {

  public static void main(String[] args) {
    JTextPane textpane = new JTextPane();
    textpane.setContentType("text/html");
    textpane.setText("<h1>News</h1><p> Java Version: " +
      System.getProperty("java.version") + "</p>");
    JOptionPane.showMessageDialog(null, textpane);
  }
}
</sscce>

Here, that compiles and runs just fine, reporting..

I converted your code to an SSCCE:

import javax.swing.JTextPane;

public class IdentifierExpected
  {
  /**
   * test harness
   *
   * @param args not used
   */
  public static void main ( String[] args )
     {
     JTextPane textAreaTop;
     textAreaTop = new JTextPane();
     textAreaTop.setContentType( "text/html" );
     }
  }

It compiles just fine. That means the problem is elsewhere in the code
that you did not show us.  Most likely you forgot or screwed up the
import.

You were complaining of a compile time problem, so all my SSCCE had to
do was compile.  I was not about to imaginatively write a whole mini
app for you that actually did something. Neither would you have had to
do that if all you were seeking help with was the compile problem.

JTextPane is a subclass of JEditorPane, setContentType & setText are
methods of JEditorPane.

See more example about JEditorPane at http://kickjava.com/348.htm
