Bug ID: 495064
Summary: Java AWT TrayIcon stopped working on KDE 6.6 Plasma
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: unspecified
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: perini.dav...@dpsoftware.org
CC: aleix...@kde.org
Target Milestone: ---
Running Ubuntu 24.10 and KDE 6.6 Plasma.
Java TrayIcon stopped working.
With this simple code:
```
import java.awt.*;
import java.awt.event.*;
public class TrayIconExample {
public static void main(String[] args) {
if (SystemTray.isSupported()) {
SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().createImage("icon.png");
TrayIcon trayIcon = new TrayIcon(image, "Tray Demo");
trayIcon.setImageAutoSize(true);
trayIcon.setToolTip("Tray Icon Demo");
trayIcon.addMouseListener(new MouseAdapter() {
u/Override
public void mouseClicked(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON1) {
System.out.println("Left button clicked");
} else if (e.getButton() == MouseEvent.BUTTON3) {
System.out.println("Right button clicked");
} else if (e.getButton() == MouseEvent.BUTTON2) {
System.out.println("Middle button clicked");
}
}
});
try {
tray.add(trayIcon);
} catch (AWTException e) {
System.err.println("TrayIcon could not be added.");
}
} else {
System.err.println("System tray not supported!");
}
}
}
```
Tray icon is correctly added to the tray bar but there is no way to listen to
mouse button on it making it unusable.
No event is triggered when I click on the tray icon.
This issue is blocking making all Java programs that uses a tray icon to not
work correcly.
