Problems with QMenu and QSystemTrayIcon

Mizmas

Hi, I'm trying to add a QMenu to the applications tray icon, and am experiencing a few problems.

Problem #1: The system tray closes when I hover outside the menu of the my app

Normal:
alt text
Mine:

Problem #2: I'm trying to style the menu with a stylesheet, but there's some weird behaviour.

For example, the I increased the border-radius to show that the background color overflows outside of its border.
I also can't seem to decrease the size of the QIcon in the stylesheet.

This is how I make the tray and menu:

        # Create tray and set icon
        self.tray = QSystemTrayIcon(self)
        self.tray.setIcon(QIcon(":/Icons/master.png"))

        # Add a context menu to the tray icon
        self.tray_menu = QMenu()

        # Create quit action
        quit_action = QAction(QIcon(":/Icons/exit.png"), "Quit", self)
        quit_action.triggered.connect(sys.exit)
        self.tray_menu.addAction(quit_action)

        # Add menu to tray
        self.tray.setContextMenu(self.tray_menu)

        # Connect the tray icon activation event
        self.tray.activated.connect(self.tray_icon_clicked)

And then set the stylesheet:

        # Apply stylesheet to tray menu
        self.tray_menu.setStyleSheet("""
            QMenu {
                background-color: #1e1e29;
                color: white;
                font: 8pt "Heebo SemiBold";
                border: 2px solid #107672;
                border-radius: 10px;
            }

            QMenu::item {
                padding: 2px;
                padding-left: 10px;
            }

            QMenu::item:selected {
                background-color: #343446;
            }

            QMenu::icon {
                padding: 10px;  # Didn't work
                height: 2px;    # Didn't work
            }
        """)

I seem to have fixed the overflow issue with:

self.tray_menu.setWindowFlags(self.tray_menu.windowFlags() | Qt.WindowType.FramelessWindowHint)
self.tray_menu.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)

Hi, you can use property-iconSize in qss to change the icon size.

I'm a C++er, not a Pythonologist;
But I have a hinge that qApp->setQuitOnLastWindowClosed(false); is what would solve the C++ version of your issue.

@Axel-Spoerl Didn't work :P

    my_app.setQuitOnLastWindowClosed(False)

Here's an example I've made that anyone can run, you will need to replace self.path_to_tray_image to a path of an image in order for it to actually appear in the system tray.

self.path_to_tray_image = "C:/Users/username/Downloads/image.png"

import sys
from PyQt6.QtWidgets import QApplication, QMainWindow, QPushButton, QSystemTrayIcon, QMenu
from PyQt6.QtCore import QPoint
from PyQt6.QtGui import QIcon, QAction, QCursor


class TrayApplication(QMainWindow):
    def __init__(self):
        
        # replace to your tray image
        self.path_to_tray_image = "C:/Users/username/Downloads/image.png"

        super().__init__()
        self.setWindowTitle("Tray Example")
        self.setGeometry(100, 100, 400, 300)

        # Create a button to minimize to tray
        self.minimize_button = QPushButton("Minimize to Tray", self)
        self.minimize_button.setGeometry(150, 120, 100, 40)
        self.minimize_button.clicked.connect(self.minimize_to_tray)

        # Set up the system tray icon
        self.tray_icon = QSystemTrayIcon(self)
        self.tray_icon.setIcon(QIcon(self.path_to_tray_image))  # Replace with your icon file

        # Add a context menu to the tray icon
        self.tray_menu = QMenu()

        quit_action = QAction(QIcon(":/path_to_exit_action_image"), "Quit", self)  # Replace with your icon file
        quit_action.triggered.connect(self.close_application)
        self.tray_menu.addAction(quit_action)

        # Connect the tray icon activation event
        self.tray_icon.activated.connect(self.tray_icon_clicked)

    def minimize_to_tray(self):
        self.hide()
        self.tray_icon.show()

    def restore_from_tray(self):
        self.show()
        self.tray_icon.hide()

    def tray_icon_clicked(self, reason):
        # Left click
        if reason == QSystemTrayIcon.ActivationReason.Trigger:
            self.restore_from_tray()

        # Right click
        elif reason == QSystemTrayIcon.ActivationReason.Context:
            # Get the current cursor position
            cursor_pos = QCursor.pos()

            # Calculate the menu position: align bottom-right corner of the menu to the cursor
            menu_width = self.tray_menu.sizeHint().width()
            menu_height = self.tray_menu.sizeHint().height()
            pos = QPoint(cursor_pos.x() - menu_width, cursor_pos.y() - menu_height)

            # Show the menu at the calculated position
            self.tray_menu.popup(pos)

    def close_application(self):
        self.tray_icon.hide()
        self.close()


if __name__ == "__main__":
    app = QApplication(sys.argv)

    window = TrayApplication()
    window.show()

    sys.exit(app.exec())
