How to add an icon to an exe in qt5 that would not be in the folder?

Question

Python

When I run it with an icon in the folder, it works, but when I remove the icon from the folder, there are no icons!

app_icon = QtGui.QIcon()
        app_icon.addFile('1.ico', QtCore.QSize(16,16))
        app_icon.addFile('3.ico', QtCore.QSize(24,24))
        app_icon.addFile('4.ico', QtCore.QSize(32,32))
        app_icon.addFile('5.ico', QtCore.QSize(48,48))
        app_icon.addFile('10.ico', QtCore.QSize(118,118))
        Dialog.setWindowIcon(app_icon)

How to embed in exe file?

Compiled like this:

pyinstaller --onefile --icon=1.ico -w outputpyfile.py

In the folder, the program shows an icon, but if you run it, you can see that the icon does not work in qt itself

Answer 1

Using the environment variable _MEIPASS will save the poor cat from starvation. I have answered questions like this many times here. Whether you added an icon to the "distribution", I don't know. One, maybe, but obviously not all.
