[SOLVED] Hyperlink

[Mir]

Hello Mir.

On the Forums, my name is Tim.

Swearing, daGame, degrades our Forums and I do not agree with the usage of such language on Java Forums. Mir made a simple mistake as we are all human.

In Java, if you want a GUI component to behave differently than normal, then you must derive a new component from it. It is different from other languages, say Visual Basics or Pascal, where new methods are added for new events for different components. That is why I created HyperLabel. The HyperLabel will handle any special events, a click in this example, without the knowledge of the user. This is called encapsulation, which is another reason I did this.

Try changing the URL to

http://www.google.com

If this doesn't work then the problem is elsewhere. However, it is strange that you got an error, because it works fine on my machine. ;)

Good luck Mir :D

ok Tim

I got your point.But problem is that i am not expert in java.First i have face a loat problem to set picture and label on dialog.Then "Niveditha" help me to solve that problem.Now if i change that code and worki in new style then i have again more problem.So i want to know how i can add backgroung picture on HyperLabel. Or Can i do work of hyperlink on same code. "Niveditha" code is here

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

public class ProgressSample2 {
  public static void main(String args[]) {
    final JProgressBar aJProgressBar = new JProgressBar(0, 100);
    aJProgressBar.setIndeterminate(true);

    JButton aJButton = new JButton("Toggle");

    ActionListener actionListener = new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        boolean indeterminate = aJProgressBar.isIndeterminate();
        aJProgressBar.setIndeterminate(!indeterminate);
      }
    };

    aJButton.addActionListener(actionListener);

    JFrame theFrame = new JFrame("Indeterminate");
    theFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container contentPane = theFrame.getContentPane();
    contentPane.add(aJProgressBar, BorderLayout.NORTH);
    contentPane.add(aJButton, BorderLayout.SOUTH);
    theFrame.setSize(300, 100);
    theFrame.show();
  }
}

I am doing work on About form. And i promiss to all of you i learn java after monday,becouse my project is just over next day.So plz help me

[Mir]

Mir, you got lots of explanation on this. As Tim, Neviditha says I'm trying to help you. I have exact code you want with me. Because I have already done those kind of things thousand times in my life up to now. I can just copy-paste the code here. But that's not the point here in our community.

Forum is a place discuss some matters/issues with friends all over the world. So you can gather wast knowledge from there. Because people have different levels of knowledge in the field. Just asking code/help like you Mir, it's not good.

So try all suggestions you have. That code given by Tim working extremely fine. So the problem is in your side.

Ok sir

i am going through your idea but after Monday.Becouse my project is just over.It's my last task to do on this project..

Thxs

Yes, it's better. Try something. And also before use any code you get try to identify what exactly it's done, and also how it's related to your question and last how to integrate in to your code without any issue at all.

Sir i set the link only this url.But HAND_CURSOR showing all over the dialog. So how can i remove this...

[Eranga]

You are asking same thing again and again. That is because you working on the dialog, not on the label you want.
