How to set a window icon with PyQt5?

In PyQt5, you can set a window icon using the QApplication class. Here's how you can set a window icon for your PyQt5 application:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow from PyQt5.QtGui import QIcon class MyWindow(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle('Window with Icon') self.setGeometry(100, 100, 800, 600) # Set window icon icon = QIcon('path_to_your_icon_file.png') # Replace with your icon file path self.setWindowIcon(icon) if __name__ == '__main__': app = QApplication(sys.argv) window = MyWindow() window.show() sys.exit(app.exec_())

Replace 'path_to_your_icon_file.png' with the actual path to your icon image file. The icon file should be in a supported image format, such as PNG.

In this example, the setWindowIcon() method of the QMainWindow class is used to set the window icon. The QIcon class is used to create an icon from the specified image file. The show() method displays the window, and app.exec_() starts the PyQt5 application event loop.

Remember to install PyQt5 (pip install PyQt5) if you haven't already.
