Steps to Change Icon

To change the icon of a QCommandLinkButton, follow these steps:

1. Import the necessary PyQt5 modules:

from PyQt5.QtWidgets import QApplication, QMainWindow, QCommandLinkButton
from PyQt5.QtGui import QIcon

2. Create a QMainWindow:

app = QApplication([])
window = QMainWindow()

3. Create a QCommandLinkButton with default text and icon:

button = QCommandLinkButton('Click me')

4. Set the icon of the QCommandLinkButton using QIcon:

icon = QIcon('path_to_icon')
button.setIcon(icon)

Note: Replace 'path_to_icon' with the actual path to the icon image file.
