Icons in PyQt application not showing up

If you're encountering issues with icons not displaying in your PyQt application, here's a solution that has helped others resolve this problem:

1. Add "icons" to the Prefix: In your resource file (.qrc), add "icons" to the prefix of the resources. For instance, if you have an icon named "icon.png," you would change the prefix to "icons.icon.png."
2. Convert .qrc File to Python Code: Use the pyside-rcc tool to convert the .qrc file into a Python code file, such as icons_rc.py. Refer to the PyQt documentation page for guidance on using pyside-rcc.
3. Import the Generated Python Code: In your main Python script, import the generated Python code (e.g., import icons_rc) to access the icons.

After implementing these steps, the icons should appear correctly in your PyQt application.

Additionally, for those using PyQt5 or PyQt6 on Python, here's a crucial tip:

When compiling or designing your application, use the MEI PASS to specify the location of the icons. This ensures that the executable can find the icons in the temporary folder rather than the executable's location.

executable_dir = getattr(sys, '_MEIPASS', os.path.abspath(os.path.dirname(sys.argv[0])))

By incorporating this code, you can ensure that the icons will be correctly displayed in your PyQt application.
