Re: using HTML in JLabels

Hi all,
I am currently devloping a java application that has a dialogue box
with a JLabel with HTML embedded into it the label. This works fine
however I want to make a section of the text a link to a file. The
problem is I am adding the code and it is recognising that I have
added a link because part of the text has turned blue and underlined
but java is not recognising it as a link that I can click on.
Any help in this matter would be highly appreciated.
Thank you
JEditorPane has a built in listener for catching HyperlinkEvents.
JLabel does not. You could probably duplicate this with some sort of
mouse listener on the JLabel but the code below will probably work for
you. This requires 1.6 or later for the Desktop class.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class test {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
JFrame f = new JFrame();
f.setLayout(new FlowLayout());
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JEditorPane p = new JEditorPane(
"text/html","<a href=http://www.knutejohnson.com>my
website</a>");
p.setBackground(Color.RED);
p.setEditable(false);
p.addHyperlinkListener(new HyperlinkListener() {
public void hyperlinkUpdate(HyperlinkEvent he) {
if (he.getEventType() ==
HyperlinkEvent.EventType.ACTIVATED) {
try {
Desktop top = Desktop.getDesktop();
top.browse(he.getURL().toURI());
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
f.add(p);
f.pack();
f.setVisible(true);
}
});
}
}
