package com.abc.dao;
import java.awt.AWTException;
import java.awt.CheckboxMenuItem;
import java.awt.Menu;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
public class MyTaskTray {
public static void main(String arg[]){
//Check the SystemTray is supported
if (!SystemTray.isSupported()) {
System.out.println("SystemTray is not supported");
return;
}
final PopupMenu popup = new PopupMenu();
final TrayIcon trayIcon =
new TrayIcon(Toolkit.getDefaultToolkit().getImage(new java.io.File("").getAbsolutePath()+"/bin/img/titleImg.jpg"), "Library Drop");
final SystemTray tray = SystemTray.getSystemTray();
// Create a pop-up menu components
MenuItem aboutItem = new MenuItem("About");
CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size");
CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip");
Menu displayMenu = new Menu("Display");
MenuItem errorItem = new MenuItem("Error");
MenuItem warningItem = new MenuItem("Warning");
MenuItem infoItem = new MenuItem("Info");
MenuItem noneItem = new MenuItem("None");
MenuItem exitItem = new MenuItem("Exit");
//Add components to pop-up menu
popup.add(aboutItem);
popup.addSeparator();
popup.add(cb1);
popup.add(cb2);
popup.addSeparator();
popup.add(displayMenu);
displayMenu.add(errorItem);
displayMenu.add(warningItem);
displayMenu.add(infoItem);
displayMenu.add(noneItem);
popup.add(exitItem);
trayIcon.setPopupMenu(popup);
try {
tray.add(trayIcon);
} catch (AWTException e) {
System.out.println("TrayIcon could not be added.");
}
}
}
What you actually lack is a parent component to show your PopupMenu. One way to achieve this, is to use an "invisible" frame (actually it is visible but with 0-bounds and undecorated, so you can't see it) like this:
import java.awt.AWTException;
import java.awt.CheckboxMenuItem;
import java.awt.Frame;
import java.awt.Menu;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.net.MalformedURLException;
import java.net.URL;
public class MyTaskTray {
public static void main(String arg[]) throws MalformedURLException {
final Frame frame = new Frame("");
frame.setUndecorated(true);
// Check the SystemTray is supported
if (!SystemTray.isSupported()) {
System.out.println("SystemTray is not supported");
return;
}
final TrayIcon trayIcon = new TrayIcon(Toolkit.getDefaultToolkit().getImage(
new URL("http://home.comcast.net/~supportcd/Icons/Java_Required.jpg")), "Library Drop");
final SystemTray tray = SystemTray.getSystemTray();
// Create a pop-up menu components
final PopupMenu popup = createPopupMenu();
trayIcon.setPopupMenu(popup);
trayIcon.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON1) {
frame.add(popup);
popup.show(frame, e.getXOnScreen(), e.getYOnScreen());
}
}
});
try {
frame.setResizable(false);
frame.setVisible(true);
tray.add(trayIcon);
} catch (AWTException e) {
System.out.println("TrayIcon could not be added.");
}
}
protected static PopupMenu createPopupMenu() {
final PopupMenu popup = new PopupMenu();
MenuItem aboutItem = new MenuItem("About");
CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size");
CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip");
Menu displayMenu = new Menu("Display");
MenuItem errorItem = new MenuItem("Error");
MenuItem warningItem = new MenuItem("Warning");
MenuItem infoItem = new MenuItem("Info");
MenuItem noneItem = new MenuItem("None");
MenuItem exitItem = new MenuItem("Exit");
// Add components to pop-up menu
popup.add(aboutItem);
popup.addSeparator();
popup.add(cb1);
popup.add(cb2);
popup.addSeparator();
popup.add(displayMenu);
displayMenu.add(errorItem);
displayMenu.add(warningItem);
displayMenu.add(infoItem);
displayMenu.add(noneItem);
popup.add(exitItem);
return popup;
}
}
As of Java 1.7, you can add the following line to remove the application bar from the taskbar:
frame.setType(Type.UTILITY);
