I have a little control-panel, just a little application that I made. I would like to minimize/put the control-panel up/down with the systemicons, together with battery life, date, networks etc.
Anyone that can give me a clue, link to a tutorial or something to read?
As of Java 6, this is supported in the SystemTray and TrayIcon classes. SystemTray has a pretty extensive example in its Javadocs:
TrayIcon trayIcon = null;
if (SystemTray.isSupported()) {
// get the SystemTray instance
SystemTray tray = SystemTray.getSystemTray();
// load an image
Image image = Toolkit.getDefaultToolkit().getImage("your_image/path_here.gif");
// create a action listener to listen for default action executed on the tray icon
ActionListener listener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
// execute default action of the application
// ...
}
};
// create a popup menu
PopupMenu popup = new PopupMenu();
// create menu item for the default action
MenuItem defaultItem = new MenuItem(...);
defaultItem.addActionListener(listener);
popup.add(defaultItem);
/// ... add other items
// construct a TrayIcon
trayIcon = new TrayIcon(image, "Tray Demo", popup);
// set the TrayIcon properties
trayIcon.addActionListener(listener);
// ...
// add the tray image
try {
tray.add(trayIcon);
} catch (AWTException e) {
System.err.println(e);
}
// ...
} else {
// disable tray option in your application or
// perform other actions
...
}
// ...
// some time later
// the application state has changed - update the image
if (trayIcon != null) {
trayIcon.setImage(updatedImage);
}
// ...

It's very simple
import java.awt.*;
import java.awt.event.*;
import javax.swing.JOptionPane;
public class SystemTrayDemo{
//start of main method
public static void main(String []args){
//checking for support
if(!SystemTray.isSupported()){
System.out.println("System tray is not supported !!! ");
return ;
}
//get the systemTray of the system
SystemTray systemTray = SystemTray.getSystemTray();
//get default toolkit
//Toolkit toolkit = Toolkit.getDefaultToolkit();
//get image
//Toolkit.getDefaultToolkit().getImage("src/resources/busylogo.jpg");
Image image = Toolkit.getDefaultToolkit().getImage("src/images/1.gif");
//popupmenu
PopupMenu trayPopupMenu = new PopupMenu();
//1t menuitem for popupmenu
MenuItem action = new MenuItem("Action");
action.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "Action Clicked");
}
});
trayPopupMenu.add(action);
//2nd menuitem of popupmenu
MenuItem close = new MenuItem("Close");
close.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
trayPopupMenu.add(close);
//setting tray icon
TrayIcon trayIcon = new TrayIcon(image, "SystemTray Demo", trayPopupMenu);
//adjust to default size as per system recommendation
trayIcon.setImageAutoSize(true);
try{
systemTray.add(trayIcon);
}catch(AWTException awtException){
awtException.printStackTrace();
}
System.out.println("end of main");
}//end of main
}//end of class
Set appropriate path for image and then run the program. t.y. :)
This is the code you can use to access and customize the system tray:
final TrayIcon trayIcon;
if (SystemTray.isSupported()) {
SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("tray.gif");
MouseListener mouseListener = new MouseListener() {
public void mouseClicked(MouseEvent e) {
System.out.println("Tray Icon - Mouse clicked!");
}
public void mouseEntered(MouseEvent e) {
System.out.println("Tray Icon - Mouse entered!");
}
public void mouseExited(MouseEvent e) {
System.out.println("Tray Icon - Mouse exited!");
}
public void mousePressed(MouseEvent e) {
System.out.println("Tray Icon - Mouse pressed!");
}
public void mouseReleased(MouseEvent e) {
System.out.println("Tray Icon - Mouse released!");
}
};
ActionListener exitListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("Exiting...");
System.exit(0);
}
};
PopupMenu popup = new PopupMenu();
MenuItem defaultItem = new MenuItem("Exit");
defaultItem.addActionListener(exitListener);
popup.add(defaultItem);
trayIcon = new TrayIcon(image, "Tray Demo", popup);
ActionListener actionListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
trayIcon.displayMessage("Action Event",
"An Action Event Has Been Performed!",
TrayIcon.MessageType.INFO);
}
};
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 Tray is not supported
}

I need some guidance in how to get the application to show up from the System Tray when I click on it.
I have managed to minimize the app on closure but I can't make it to show up.
If I'm builduing a new shell with same Contents would help?(I am building a SWT application)
This is how I am initializing my Shell: (I have modified it so I don't use AWT with SWT)
protected Shell shlSmartHouseSystem;
public void open() {
Display display = Display.getDefault();
createContents();
shlSmartHouseSystem.open();
shlSmartHouseSystem.layout();
while (!shlSmartHouseSystem.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
}
And this is my function where I am minimizing in Tray:
public void minimizeToTrayOnClose() {
final Display display = shlSmartHouseSystem.getDisplay();
Image image = new Image(display,"D:\\VIA_University_(Embedded_Systems)\\AJP_Workspace\\HouseSystem_Server\\icon-smart-house.png");
Tray tray = display.getSystemTray();
if (tray != null) {
TrayItem trayItm = new TrayItem(tray,SWT.NONE);
trayItm.setImage(image);
final Menu menu = new Menu(shlSmartHouseSystem, SWT.POP_UP);
MenuItem menuItem = new MenuItem(menu, SWT.PUSH);
menuItem.setText("Show");
menuItem.addListener (SWT.Selection, new Listener () {
public void handleEvent (Event e) {
System.out.println("Opened");
}
});
menuItem = new MenuItem(menu, SWT.PUSH);
menuItem.setText("Exit");
menuItem.addListener (SWT.Selection, new Listener () {
public void handleEvent (Event e) {
System.exit(0);
}
});
trayItm.addListener (SWT.MenuDetect, new Listener () {
public void handleEvent (Event event) {
menu.setVisible (true);
}
});
}
}
I have menu in my application, and I want to set menu item normal state icon, and pressed state icon. Normal state icon is added, but when I press menu item, normal state icon is not changed by pressed state icon. What is problem here:
JMenu m=new JMenu(text);
m.setBackground(getTheme().colors.menuColor());
m.setOpaque(false);
m.setIcon(core.getIcon(text, "normal"));
m.setPressedIcon(core.getIcon("webmaps", "pressed"));
This issue has been seen before. The inherited setPressedIcon does not change the background Icon on the the JMenu (or indeed JMenuItem). You could use a MenuListener on the component as a workaround:
m.addMenuListener(new MenuListener() {
#Override
public void menuSelected(MenuEvent e) {
JMenu menu = (JMenu) e.getSource();
menu.setIcon(core.getIcon("webmaps", "pressed"));
}
#Override
public void menuDeselected(MenuEvent e) {
JMenu menu = (JMenu) e.getSource();
menu.setIcon(core.getIcon(text, "normal"));
}
#Override
public void menuCanceled(MenuEvent e) {
JMenu menu = (JMenu) e.getSource();
menu.setIcon(core.getIcon(text, "normal"));
}
});
i am working on a java project and i want to display a message in popup like the popup of "Safe To Remove Hardware" occurred in the windows when we click on the Eject icon for USB Drives.
I want show my message in the same kind of popup using java code.
Use the SystemTray class.
To create an icon with a tooltip, use something like this:
SystemTray tray = SystemTray.getSystemTray();
TrayIcon icon = new TrayIcon(....);
icon.setToolTip("I have finished my work");
icon.setActionListener(this);
tray.add(trayIcon);
Then in the class that displays the tooltip, implement the ActionListener interface to be informed when the user clicks on the icon and/or the tooltip (that's what the setActionListener() is for)
For more details refer to the Javadocs of SystemTray, TrayIcon and ActionListener
You simply need to use the displayMessage(...) method of the TrayIcon class.
Try your hands on this code, is this what you wanted :
import java.awt.*;
import java.net.URL;
import javax.swing.*;
public class BalloonExample
{
private void createAndDisplayGUI()
{
TrayIcon trayIcon = new TrayIcon(createImage(
"/image/caIcon.png", "tray icon"));
SystemTray tray = SystemTray.getSystemTray();
try
{
tray.add(trayIcon);
}
catch (AWTException e)
{
System.out.println("TrayIcon could not be added.");
return;
}
trayIcon.displayMessage("Balloon", "My First Balloon", TrayIcon.MessageType.INFO);
}
//Obtain the image URL
protected static Image createImage(String path, String description) {
URL imageURL = BalloonExample.class.getResource(path);
if (imageURL == null) {
System.err.println("Resource not found: " + path);
return null;
} else {
return (new ImageIcon(imageURL, description)).getImage();
}
}
public static void main(String... args)
{
SwingUtilities.invokeLater(new Runnable()
{
public void run()
{
new BalloonExample().createAndDisplayGUI();
}
});
}
}
Have a look at my question here. Basically that tooltip is a Balloon tip and you can use ShellNotifyIcon to create one.
I want to add my application to the system tray when it's window is closed (similar to the Google Talk application). And then when I click the on icon in the system tray the application window becomes active again. How can I do this in Java?
final SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("images.jpg");
final TrayIcon trayIcon = new TrayIcon(image);
try {
SystemTray.getSystemTray().add(trayIcon);
} catch (AWTException e2) {
e2.printStackTrace();
}
this.addWindowStateListener(new WindowStateListener() {
public void windowStateChanged(WindowEvent e) {
if (e.getNewState() == EXIT_ON_CLOSE) {
trayIcon.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
setVisible(true);
}
});
setVisible(false);
}
}
});
you have set DefaultCloseOperations correctly
myFrame.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE)
this code line is same as myFrame.setVisible(false), then for restore of JFrame from JPopupMenu to call only myFrame.setVisible(true)
I got answer. Now when i close window its closing and when i click on System tray icon then it again open my window
Image image = Toolkit.getDefaultToolkit().getImage("src/resources/ChatIcon1.jpeg");
final TrayIcon trayIcon = new TrayIcon(image);
trayIcon.setToolTip("OfficeCommunicator");
try {
SystemTray.getSystemTray().add(trayIcon);
} catch (AWTException e2) {
e2.printStackTrace();
}
trayIcon.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
trayIcon.displayMessage("hi", "You Opened Me Again", TrayIcon.MessageType.INFO);
setVisible(true);
}
});
}
I would like to show my own icon instead of the Java cup in the window.
Also when minimized, I would like to display, my own image. How will I be able to do so?
And where should I position my image relative to the source file?
[UPDATE]
I tried but no luck
TrayIcon trayIcon = new TrayIcon(Toolkit.getDefaultToolkit().createImage("image/accounting.gif"));
//setIconImage();
SystemTray tray = SystemTray.getSystemTray();
try {
tray.add(trayIcon);
} catch (AWTException e) {
System.out.println("TrayIcon could not be added.");
}
Also i tried
TrayIcon trayIcon = new TrayIcon(createImage("images/bulb.gif", "tray icon"));
But seriously doubt createImage( and even if it is Object don't know what to import.
Regards,
Regarding your TrayIcon issue, you can refer below for a solution:
public static void createSystemTrayIcon() {
if (SystemTray.isSupported()) {
SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage(
System.getenv("MY_PROGRAM_HOME") + "game.ico"
);
PopupMenu popup = new PopupMenu();
final MenuItem menuExit = new MenuItem("Quit");
MouseListener mouseListener =
new MouseListener() {
public void mouseClicked(MouseEvent e) {}
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) {
Runtime r = Runtime.getRuntime();
System.out.println("Exiting...");
r.exit(0);
}
};
menuExit.addActionListener(exitListener);
popup.add(menuExit);
final TrayIcon trayIcon = new TrayIcon(image, "My program", popup);
ActionListener actionListener =
new ActionListener() {
public void actionPerformed(ActionEvent e) {
trayIcon.displayMessage(
"My program ",
"version: blahblah",
TrayIcon.MessageType.INFO
);
}
};
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 Tray is not supported
}
}
Use JFrame.setIconImage()
An example using setIconImages() : (same applies for setIconImage())
public MyFrame() {
initComponents(); //Added by Netbeans
List<Image> icons = new ArrayList();
icons.add(new ImageIcon(getClass().getResource("/com/example/icons/16/app.png")).getImage());
icons.add(new ImageIcon(getClass().getResource("/com/example/icons/32/app.png")).getImage());
this.setIconImages(icons);
}
The clue is in using the "getImage()" in order to return the Image (as ImageIcon can not be used directly in setIconImages() ).
I havent written about tray icon but Finally I found the main issue in setting the jframe icon. Here is my code. It is similar to other codes but here are few things to mind the game.
this.setIconImage(new ImageIcon(getClass().getResource("Icon.png")).getImage());
1) Put this code in jframe WindowOpened event
2) Put Image in main folder where all of your form and java files are created e.g.
src\ myproject\ myFrame.form
src\ myproject\ myFrame.java
src\ myproject\ OtherFrame.form
src\ myproject\ OtherFrame.java
src\ myproject\ Icon.png
3) And most important that name of file is case sensitive that is icon.png won't work but Icon.png.
this way your icon will be there even after finally building your project.
