QSystemTrayIcon doesn't show messages

[superaga]

Hi all,

I can make the systray icon appear in the systraybar (Win 10) with its menu.
I can trigger actions from the menu, but I can't see any notification using the showMessage method.

I made a small example to show the issue I'm having:

import sys
from typing import Dict
from PyQt6.QtWidgets import QApplication, QSystemTrayIcon, QStyle, QMenu
from PyQt6.QtCore import QObject, pyqtSignal, QTimer
from PyQt6.QtGui import QIcon, QAction


class SysTray(QObject):
    def __init__(self, app: QApplication) -> None:
        super().__init__(parent=None)

        self.systray = QSystemTrayIcon()
        if not self.systray.isSystemTrayAvailable():
            print("System tray not available for this system")
            return

        icon = QIcon("icon_system.png")
        self.systray.setIcon(icon)
        self.systray.setVisible(True)
        self.systray.setToolTip("My running systray example")
        self.timer = QTimer()

        self._make_menu()
        self.systray.setContextMenu(self.menu)

    def _make_menu(self) -> None:
        self.menu = QMenu()
        self.tmr_single = QAction("Trigger one shot timer")
        self.tmr_periodic = QAction("Trigger periodic timer")
        self.tmr_stop = QAction("Stop timer")
        self.item_quit = QAction("Quit")

        self.menu.addAction(self.tmr_single)
        self.menu.addAction(self.tmr_periodic)
        self.menu.addAction(self.tmr_stop)
        self.menu.addAction(self.item_quit)

    def timer_single(self) -> None:
        self.timer.setSingleShot(True)
        self.timer.timeout.connect(self.msg_timer_single)
        self.timer.start(3000)

    def msg_timer_single(self) -> None:
        msg = {
            "title": "Single shot timer", 
            "txt": "3 seconds elapsed", 
            "icon": "info"}
        print("Single timer finished")
        self.show_msg(msg)

    def timer_periodic(self) -> None:
        self.timer.setSingleShot(False)
        self.timer.timeout.connect(self.msg_timer_periodic)
        self.timer.start(3000)

    def msg_timer_periodic(self) -> None:
        msg = {
            "title": "Periodic shot timer",
            "txt": "3 seconds elapsed",
            "icon": "warn",
        }
        print("Periodic timer finished")
        self.show_msg(msg)

    def timer_stop(self) -> None:
        self.timer.stop()

    def show_msg(self, msg: Dict) -> None:
        _icon = None
        if msg["icon"] == "info":
            _icon = QSystemTrayIcon.MessageIcon.Information
        elif msg["icon"] == "warn":
            _icon = QSystemTrayIcon.MessageIcon.Warning
        elif msg["icon"] == "error":
            _icon = QSystemTrayIcon.MessageIcon.Critical
        else:
            _icon = QSystemTrayIcon.MessageIcon.NoIcon
        self.systray.showMessage(msg["title"], msg["txt"], _icon, 1000)


def main():
    app = QApplication(sys.argv)
    systray = SysTray(app=app)
    systray.item_quit.triggered.connect(app.quit)
    systray.tmr_single.triggered.connect(systray.timer_single)
    systray.tmr_periodic.triggered.connect(systray.timer_periodic)
    systray.tmr_stop.triggered.connect(systray.timer_stop)
    sys.exit(app.exec())


if __name__ == "__main__":
    main()

This is the icon I used for the code, but you can of course use whatever you want.

I really hope that the issue would be in the code and doesn't belong to my system policies (where I'm employed) which it would make the problem then irresolvable 🤦‍♂️.

Any help would be super appreciated!

I've been able to test my code on a home Win 10 PC and it works.
So the problem it is related to my company policies.
Many thanks to all for the support!

Anyone that could at least test the code and give me a feedback?
It would be super appreciated!

I don't have a Windows 10 at hand, but at least on Linux and Windows 11 I can see the Periodic timer message being showed every 3 seconds.
(

It might be a Windows 10 issue, but I'd check if there are some related bugs.

Many thanks for this!
At least I know that the code works as expected.
I'll aks to IT if there are some restrictions or setting I'm not aware of.

Hi all,
I'd like to change the "message title" that appears in the picture as Python.

On the documentation page I couldn't find any method/properties related to that other then:

• title: See bold text in the image.
• message: See normal text in the message.
• icon: I can also decide which icon use.

Any idea?
Super thanks!

@superaga said in QSystemTrayIcon doesn't show messages:

I think it is the title of your application, try to change that

Hi @jsulm, many thanks for your reply.
I just tried both: QApplication.setApplicationDisplayName and QApplication.setApplicationName, but do not work.

Any other idea?
Cheers
