Use the function setWindowIcon function.

Setting the icon requires the import from PyQt5.QtGui import Qicon of the class library

Initialize the Qicon class with the constructor, passing in the path of the icon, and it is recommended to set the relative path.

Question: where can I download the icon?

Alibaba icon library

Https://www.iconfont.cn

Note: the download icon should be png or gif as much as possible, which makes the background of the image transparent.

In a project, we tend to put all the icons in the same folder and then call them through the relative path.

Question: what is the difference between setting icons in QWidget and setting icons in QApplication?

The icon of a form set through Qwidget's setWindowIcon can be one icon per form.

The icon of the form is set through QAapplication's setWindowIcon, and the default icon of all forms is set.

Note: only icons set by QApplication can be recognized in mac systems.
