[SOLVED] Windows Linux conflict - TrayIcon image not display in Linux

[Eranga]

Hi all,

I have create a TrayIcon and then add image and a pop-up menu into it as follows.

public void trayIconEventHandling()
    {
        TrayIcon trayIcon;
 
        if (SystemTray.isSupported()){
            SystemTray tray = SystemTray.getSystemTray();
            
         // I have to use this ActionEvent to exit the dialog as well
         // Exit from the complete application
            ActionListener exitListener = new ActionListener(){
                public void actionPerformed(ActionEvent e){
                    System.out.println("Exiting...");
                    System.exit(0);
                }
            };
            
        // Open the dialog in Actionevent
            ActionListener openDialogListner = new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    System.out.println("Open another Dialog here.");
                    new AboutWindow().setVisible(true);
                }
            };
            
        // Tray icon menu implimenting goes here
            PopupMenu popup = new PopupMenu();
            MenuItem defaultItem = new MenuItem("Exit");
            MenuItem openDlgItem = new MenuItem("About");
            MenuItem extartItem = new MenuItem("Others...");
            
            openDlgItem.setEnabled(false);
            
            defaultItem.addActionListener(exitListener);
            openDlgItem.addActionListener(openDialogListner);
            
            popup.add(defaultItem);
            popup.add(openDlgItem);
            popup.addSeparator();
            popup.add(extartItem);
 
            Image image = Toolkit.getDefaultToolkit().getImage("mytrayicon/RADAR.gif");
            trayIcon = new TrayIcon(image, "Pop-up", popup);
 
            ActionListener actionListener = new ActionListener(){
                public void actionPerformed(ActionEvent e){    
                    System.out.println("Main Dialog!");
 
                // Try to simply call the GUI here
                    mainWnd.setVisible(true);
                }
            };
            trayIcon.setImageAutoSize(true);
            trayIcon.addActionListener(actionListener);
            trayIcon.addMouseListener(mouseListener);
 
            try
            {
                tray.add(trayIcon);
            } 
            catch (AWTException e) 
            {
                System.err.println("TrayIcon could not be added.");
            }
        } 
        else{
            System.err.println("System tray is currently not supported.");
        }   
    }

My code working well on Windows, loaded the image correctly. But in Linux it don't.

As far as I know about Java, I believe my code is correct. Then why this is happened on Linux. Somebody can give me a hint that where I'm going wrong.

Important thing here is, Linux does not give any exception also. :(

Eranga, please give some more details.
What desktop/window manager do you use (I just have tested similar code in KDE 3.5.10 and anything gone well) and what Linux distribution it is?
Also, it would be very useful to know what's the version of Java your application is running on, both in Windows and in Linux.

[Eranga]

This is very old thread I've started. Actually the conflict there is not with the coding.

I'm working on the KDE 3.5 as well, with the JDK version 1.6 and I don't remember the minor version of it. I've use the latest at that time.

I've found two reasons effected on this,

1. Image size limitation, I cannot use an image around more than 2MB
2. *.gif types are not supported. *.png used

Eranga, thanks!
You've just saved us (I mean the forum members) some hours of investigation :)

I really like to help everyone through whatever I know.

Eranga, i was looking your code, was missing the main, a package mainWnd
and the method AboutWindow(), after that i had problems with a mouselistener but i think it is related with the first error. So i couldnt make it works.

[Eranga]

Actually that's a part of an application. There is no main method, it's only about the tray icon handling. What you want to do is, write a simple class and call this method in appropriate place.
