描述

Describe the bug

On non KDE environment with many KDE elements systray icon is missed in lxpanel (and in fpanel too) on openbox when dbus is available (DBUS_SESSION_BUS_ADDRESS or XDG_RUNTIME_DIR are set).

CopyQ print warning on start:

Warning: [default] QDBusTrayIcon encountered a D-Bus error: QDBusError("org.freedesktop.DBus.Error.UnknownObject", "No such object path '/StatusNotifierWatcher'")

After unset these env variables systray icon is show and work correctly.

Tested on 10.0.0 from Debian Trixie and on 13.0.0 from github. (10.0.0 systray icon was missed also when QT_QPA_PLATFORMTHEME was set)

To Reproduce (I'm not sure) run CopyQ on system with dbus but without "StatusNotifierWatcher"

Version, OS and Environment CopyQ Clipboard Manager 13.0.0 Qt: 5.15.15 KNotifications: 5.116.0 Compiler: GCC Arch: x86_64-little_endian-lp64 OS: Debian GNU/Linux 13 (trixie)

研究方向
Investigate how CopyQ initializes the system tray icon. Look for logic that decides between using QDBusTrayIcon and QSystemTrayIcon. Check the error message 'No such object path /StatusNotifierWatcher' and ensure a fallback exists when StatusNotifierWatcher is not available. The fix may involve detecting the presence of the DBus service and using the X11 tray fallback. See relevant code in the tray icon source files.
