Hi, I am trying to show more detailed information after a user clicks on the message balloon tooltip.
However, I can't find how to capture that event.
Is this possible to do?
How to capture trayicon.displayMessage() mouse click on the tooltip baloon
1) Is possible to listening MouseClickEvents by add ActionListener to the TrayIcon, then Message body listening for MouseClicked
2) (not asked directly) but I can't to give you an answer listening if message was closed by close button, and Message gone away from screen same way, but without catch any event(s)
3) looks like as this Java TrayIcon message close button should be only one solutions, because API doesn't implements another methods,
import java.awt.*;
import java.awt.event.*;
public class FullTray {
private static class ShowMessageListener implements ActionListener {
private TrayIcon trayIcon;
private String title;
private String message;
private TrayIcon.MessageType messageType;
ShowMessageListener(TrayIcon trayIcon, String title, String message, TrayIcon.MessageType messageType) {
this.trayIcon = trayIcon;
this.title = title;
this.message = message;
this.messageType = messageType;
}
public void actionPerformed(ActionEvent e) {
trayIcon.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("Message Clicked");
}
});
trayIcon.displayMessage(title, message, messageType);
}
}
public static void main(String args[]) {
Runnable runner = new Runnable() {
public void run() {
if (SystemTray.isSupported()) {
final SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("gifIcon.gif");
PopupMenu popup = new PopupMenu();
final TrayIcon trayIcon = new TrayIcon(image, "The Tip Text", popup);
MenuItem item = new MenuItem("Error");
item.addActionListener(new ShowMessageListener(trayIcon, "Error Title", "Error", TrayIcon.MessageType.ERROR));
popup.add(item);
item = new MenuItem("Warning");
item.addActionListener(new ShowMessageListener(trayIcon, "Warning Title", "Warning", TrayIcon.MessageType.WARNING));
popup.add(item);
item = new MenuItem("Info");
item.addActionListener(new ShowMessageListener(trayIcon, "Info Title", "Info", TrayIcon.MessageType.INFO));
popup.add(item);
item = new MenuItem("None");
item.addActionListener(new ShowMessageListener(trayIcon, "None Title", "None", TrayIcon.MessageType.NONE));
popup.add(item);
item = new MenuItem("Close");
item.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
tray.remove(trayIcon);
}
});
popup.add(item);
try {
tray.add(trayIcon);
} catch (AWTException e) {
System.err.println("Can't add to tray");
}
} else {
System.err.println("Tray unavailable");
}
}
};
EventQueue.invokeLater(runner);
}
private FullTray() {
}
}
I'm notified in my point 3rd. about..., maybe I'm post code for this event on this forum too, not sure –
Dentilabial
Something must have changed because this exact code is not working on my config. Running with jdk1.8.0_72 under Windows 10. Seems related to this JDK issue bugs.openjdk.java.net/browse/JDK-8146537 –
Pathognomy
Confirmed: ActionListener is not working with Java 7 - 9 (at least on Windows 10) - see bugs.openjdk.java.net/browse/JDK-8146537. I have tested Java 11 works fine –
Enervated
Even though this topic isn't exactly recent, I figured I'd share my solution since this kind of thing doesn't really change.
How To Use
To use this code, just create the 1 public class and the 2 public interfaces.
Now create an instance of the CustomTrayIcon class and call the addToSystemTray() method, once you're done initializing it.
Anytime you want to show a notification bubble, call the showBubbleNotification(...) method.
To remove this tray icon, just call the removeFromSystemTray() method.
CustomTrayIcon
This class is the base which does all of the heavy lifting.

This code is much too verbose.... You should be more concise if you want to show a point. –
Pathognomy
I wasn't proving a point but rather providing a solution. Too many people take code samples from SO and put it into production without adding proper error handling or documentation. Most of the time, they don't understand how the code works. It's not the posters fault or responsibility to do this, but I don't like posting half-assed solutions. –
