Don't use the PyQt docs (they are almost unmaintained), nor the PySide/Qt for Python pages (they are often misleading and sometimes ...

2022年5月24日 · Another important aspect to consider is that, similarly to QPixmap, when you set a QIcon on a widget, you are not actually setting that QIcon instance, but rather a copy of it. Also, QIcon is actually a sort of "abstract object", which actually interfaces with a QIconEngine that eventually returns QPixmap or paints the icon on a given paint ...
