package org.me.hello;

import java.applet.Applet;
import java.awt.AWTException;
import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.MenuItem;
import java.awt.Panel;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.TextArea;
import java.awt.TextField;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JTextField;



public class AppletIcon extends JApplet implements ActionListener{
private JButton ok = new JButton("Envoyer");
private JTextField msg = new JTextField("",35);
    public void init(){
    //setLayout ( new BorderLayout());
     ok.addActionListener(this);
     this.getContentPane().add(ok,BorderLayout.SOUTH);
     this.getContentPane().add(msg,BorderLayout.NORTH);
}
public void actionPerformed(ActionEvent act) {
 
final TrayIcon trayIcon;

if (SystemTray.isSupported()) {

SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("tray.gif");
//PopupMenu popup = new PopupMenu();
trayIcon = new TrayIcon(image, "Platforme");

ActionListener actionListener = new ActionListener() {

public void actionPerformed(ActionEvent e) {

trayIcon.displayMessage("You have a new message", msg.getText(), TrayIcon.MessageType.INFO);
                     
        }
    };


trayIcon.setImageAutoSize(true);

trayIcon.addActionListener(actionListener);

try {
        tray.add(trayIcon);
    }
catch (AWTException e) {
        System.err.println("TrayIcon could not be added.");

 }


}

 }

}

my problem is that in the html page the icon is not displayed.
Thank you for your support

Is the applet in its JAR ?

[Eranga]

You cannot do this from the applet, it dosen't have the control over the user desktop.

[Eranga]

At least, did you debug the code?

[Webuser]

Emm...
Applet can run as a desktop app unless it is signed.
So do next:
1) put your applet into jar
2) put the image into jar
3) invoke image as A.class.getResourceAsStream("*.PNG"); where A is an empty anchor class
4) sign the applet jar

And then I think that should work... If not come here again ;)

Of course that's fine. But that's not what OP is tried. He dosen't do anything like that.

[Webuser]

But the author can replace applet with a JWS application and that would be more interesting I guess :)

[Eranga]

Agreed. But even as you said applet can be run as a desktop application, which not tried by OP. :)

[ramroum]

thank you for your help.
I'm a beginner in java is that you can tell me how to put the applet and the image in a file. jar

how to put the applet and the image in a file. jar

That's done using the jar command. Read the API doc for jar and also do a search for the many sample usages on the forum.

Check on Suns' tutorial as well. You can find lots of useful hints there.

You can do this easy with WinRAR program ;)
Also with your IDE...
Or study the jar util commands

Webuser, please come back to my thread I am really not able to understand why my applet cannot run :(

[Webuser]

Webuser, please come back to my thread I am really not able to understand why my applet cannot run :(

It's OK, gafa, I am watching the threads' list :)
I am to come back a little bit later ...

This is what I'm suggesting to move with as a Java developer. Better not to stick with other stuff at the time of learning the basis.

Watch your code closely. You are trying to access the system tray :rolleyes:
Browser is not about here :D

watch it

if (SystemTray.isSupported()) {

SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("tray.gif");

That's why I recommend you to use a JWS application way ;)
