how to open url from string on JOptionPane?

807600Jul 24 2007 — edited Jul 25 2007

hello there
i've made a JOptionPane that contains a string url
and i'm wondering if it is possible to add MousMotionListener
to the url and if it is possible to open that url in the default Browser?

JOptionPane.showMessageDialog(null, " Visit us at www.google.com" ,"Visit us",JOptionPane.ERROR_MESSAGE);

is it not possible?
any ideas?

I wanted to do the same thing a few weeks ago, but I gave up. It's not impossible, but a bit complicated for my needs. To open the URL in the browser you need to do a system call to open an external application (the web browser) from your Java app. Therefore you must know the correct path to the application and be aware that the syntax could change depending on the OS.
Another way could be to retrieve the remote web content and display it in a JEditorPane. In this manner you can show a remote HTML page, but you don't have the functionalities of a web browser (i.e. navigation through links). And it won't work with dynamically-generated web content.
HTH.

Feh. If you are using the current version of Java, there's no need to get your knickers in a twist:

Desktop.getDesktop().browse(uri);

????????

i know that code bigdaddy posted but i think i can't use it in my case
is that possible?

807600

Possible that you can't use it? Have you fallen and can't up?

the sense of neophyte helplessness does seem to be
permeating these forums lately.
(2 words-of-the-day down, 354 to go...)

so i have to invoke a mouse event to the url
meaning when the mouse passes on the url it is highlited and when he presses it the browser is opened

807600

why not just make your life easier and put a non editable
jeditorpane in the dialog and let it do all the work for you.

i would be so grateful if you give me a little demo or link to study
because i'm so new

Yes, there is no prepacked "hyperlink" widget in the J2SE, so you have to listen for
a mouse press. Unless you use JEditorPane, but that's overkill:

import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;

public class HyperExample extends MouseAdapter implements Runnable {
    @Override
    public void run() {
        JLabel label = new JLabel("<html><u>http://java.sun.com</u></html>");
        label.addMouseListener(this);
        JFrame f = new JFrame();
        f.getContentPane().add(label);
        f.pack();
        f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    @Override
    public void mousePressed(MouseEvent evt) {
        try {
            URI uri = new URI("http://java.sun.com");
            Desktop.getDesktop().browse(uri);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new HyperExample());
    }
}

I learn something every day. ;-) Thanks BigDaddy.

807600

thanks so much bigdaddy for the help
is there another example for the JOptionPane because it seems difficult to me

807600

i need the JOptionPane example also please

807600

Post what you have. It's not hard to display a given component on a JOptionPane.

807600

sir the following JOptionPane contains a url
i want to open the default browser when the user presses the link
by left mouse click and change the mouse cursor when it passes over the link and it is difficult to me as a newer could you help me?

807600

JOptionPane.showMessageDialog(null, " Visit us at www.google.com" ,"Visit us",JOptionPane.ERROR_MESSAGE);

807600

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class OptionPaneExample extends MouseAdapter{
    public static void main(String[] args) {
        String msg = "<html><u>http://java.sun.com</u></html>";
        JLabel url = new JLabel(msg);
        url.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
        url.addMouseListener(new OptionPaneExample());

        JPanel message = new JPanel();
        message.add(new JLabel("Visit us at "));
        message.add(url);

        JOptionPane.showMessageDialog(null, message);
    }

    public void mousePressed(MouseEvent evt) {
        System.out.println("etc...");
    }

    public void mouseEntered(MouseEvent evt) {
        evt.getComponent().setForeground(new Color(0xC0, 0xC0, 0xF0));

    }

    public void mouseExited(MouseEvent evt) {
        evt.getComponent().setForeground(Color.BLACK);
    }
}
