[SOLVED] Why the icon doesn't display in System Tray although the python code is executing without any error?

Why the icon doesn't display in System Tray although the python code is executing without any error?

I have just started learning python and trying to create a system tray icon. This program is executing without any error but isn't displaying any icon.

from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
app = QApplication([]) 
app.setQuitOnLastWindowClosed(False) 
  
# Adding an icon 
icon = QIcon("fb.png") 
  
# Adding item on the menu bar 
tray = QSystemTrayIcon() 
tray.setIcon(icon) 
tray.setVisible(True) 
  
# Creating the options 
menu = QMenu() 
option1 = QAction("Option1") 
option2 = QAction("Option2") 
menu.addAction(option1) 
menu.addAction(option2) 
  
# To quit the app 
quit = QAction("Quit") 
quit.triggered.connect(app.quit) 
menu.addAction(quit) 
  
# Adding options to the System Tray 
tray.setContextMenu(menu) 
app.exec_()

This code displays following output in VSCode

[Running] python -u "e:\python\systray\systray.py"

Solution

When you handle external files as the icon then you must use absolute paths either explicit or build them, in your case I assume that the .png is next to the script so you should use:

import os

CURRENT_DIRECTORY = os.path.dirname(os.path.realpath(__file__))
#  ...
icon = QIcon(os.path.join(CURRENT_DIRECTORY, "fb.png"))
# ...
