Doesn't seem to be distro specific, seeing this on Arch (Plasma 6.2.4, KDE Frameworks 6.8.0, Qt 6.8.1) Debian Trixie (Plasma 6.2.4, KDE Frameworks 6.6.0, Qt 6.7.2) I am also experiencing this issue with my app ControllerBuddy -> https://controllerbuddy.org As far as I can tell this appeared with KDE 6.0 - on KDE 5 the tray works flawlessly with AWT. As this issue renders the tray icon useless, in my app I even started checking for KDE versions >= 6 to handle them as if the tray is not supported at all, which is really unfortunate... :( I might be willing to look into this if nobody else cares, but at least some intial pointers on where to start digging would be helpful... |
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.
