[SOLVED] Problem with setVisible(); on LINUX

[lepetitprince]

Hello,

Could anyone please tell me why the following code does not work on LINUX but on WINDOWS and what I could do to make it work? I have tried so many workarounds but nothing really worked out, I cannot get it visible again - at least not properly! Thank you in advance!

Code:

 private void formWindowIconified(java.awt.event.WindowEvent evt) {                                     

        setVisible(false);
        
    }                                    
    
    public void SysTray () {
        
            final TrayIcon trayIcon;

            if (SystemTray.isSupported()) {

                SystemTray tray = SystemTray.getSystemTray();
                java.net.URL iconUrl = this.getClass().getResource("jack_in_box.gif");
                Image image = getToolkit().getImage(iconUrl);

                MouseListener mouseListener = new MouseListener() {

                    public void mouseClicked(MouseEvent e) {
                        setVisible(true);
                        setExtendedState(Frame.NORMAL);
                   }

                    public void mouseEntered(MouseEvent e) {

                    }

                    public void mouseExited(MouseEvent e) {

                    }

                    public void mousePressed(MouseEvent e) {

                    }

                    public void mouseReleased(MouseEvent e) {

                    }
                };

                ActionListener exitListener = new ActionListener() {
                    public void actionPerformed(ActionEvent e) {
                        System.exit(0);
                    }
                };

                PopupMenu popup = new PopupMenu();
                MenuItem defaultItem = new MenuItem("Exit");
                defaultItem.addActionListener(exitListener);
                popup.add(defaultItem);

                trayIcon = new TrayIcon(image, "CheckInBox", popup);

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

                //  System Tray is not supported

            }
        
    }

I think you use JFrame form in a IDE? So use a reference to the current object.

Code:

this.setVisible(false);

Should work.

Hi Eranga,

Thanks for the quick reply, but the problem is not the reference, the problem is that setVisible(true); in the MouseEvent does not set the JFrame visible again. It just -sometimes- blinks very fast in the panel (Task Bar), looses the focus and stays invisible. Only after I click it a couple of times I get it on the screen again. Oddly enough, it works fine on Windows. Maybe a "paint" problem?!

Thank you for further help

Ah, got the point. Did you try to use an action listener, rather using a mouse listener?

[lepetitprince]

I've just tried that - no success. Any other ideas?

[lepetitprince]

I think I have to accept that it just do not work on Linux (Gnome).

Thank you all anyway!

I don't think it;s a good idea at all. Better to try different thing there. As much as possible try to get the exceptions and see what it mean. You may have a solution.

Did you try it on formWindowOpened(). If so what happened there.
