Adding an Icon to a PySide6 Window

Python PySide6

About Lesson

In this lesson we want to talk about Adding an Icon to PySide6 Window, When we create desktop applications with PySide6, it is often useful to add an icon to the window. An icon can make the application easier to recognize and distinguish from other applications. In this lesson, we will learn how to add an icon to a PySide6 window.

Step 1: Choose an Icon

The first step is to choose an icon for your application. The icon can be in any image format, such as PNG, SVG, or ICO. The recommended size for desktop application icon is 256×256 pixels. You can create your own icon using an image editor like GIMP or Photoshop, or you can download an icon from websites like Flaticon or Iconfinder.

Step 3: Load the Icon in Your Code

To load icon in your code, you can use the QIcon class. This is the example of how to load icon file in your PySide6 code.

from PySide6.QtGui import QIcon
from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication([])
window = QMainWindow()
window.setWindowTitle("Codeloop.org")

icon = QIcon("qt.png")
window.setWindowIcon(icon)

window.show()
app.exec()

from PySide6.QtGui import QIcon

from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication([])

window = QMainWindow()

window.setWindowTitle("Codeloop.org")

icon = QIcon("qt.png")

window.setWindowIcon(icon)

window.show()

app.exec()

Run the complete code and you can see that we have the icon within our window.

Adding an Icon to a PySide6 Window

This is the code with OOP (Object Oriented Programming) and the result will be the same.

from PySide6.QtGui import QIcon
from PySide6.QtWidgets import QApplication, QMainWindow

class MyWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Codeloop.org")

        icon = QIcon("qt.png")
        self.setWindowIcon(icon)

        self.show()

app = QApplication([])
window = MyWindow()
app.exec()

from PySide6.QtGui import QIcon

from PySide6.QtWidgets import QApplication, QMainWindow

class MyWindow(QMainWindow):

def __init__(self):

super().__init__()

self.setWindowTitle("Codeloop.org")

icon = QIcon("qt.png")

self.setWindowIcon(icon)

self.show()

app = QApplication([])

window = MyWindow()

app.exec()

By using OOP with PySide6, we can encapsulate the logic and behavior of the window within its own class, making it easier to manage and modify in the future. We can also create multiple instances of the MyWindow class with different icons, if desired.
