Getting Started with PySide6: Building Your First Window

In this article we want to learn about Getting Started with PySide6: Building Your First Window.

What is PySide6 ?

PySide6 is Python binding for the cross-platform graphical user interface (GUI) toolkit Qt. It is powerful tool that can be used to develop desktop applications that are compatible with multiple operating systems such as Windows, Linux, and macOS.

In this article, we will provide a brief introduction to PySide6 and demonstrate how to create basic window using PySide6.

Getting Started with PySide6

To get started with PySide6, you will need to install it on your system. You can do this by running the following command in your terminal:

pip install PySide6

1	pip install PySide6

Once you have installed PySide6, you can begin creating your first window.

Creating a Basic Window

for creating basic window in PySide6, you will need to create QApplication object and QMainWindow object. The QApplication object is responsible for managing the application’s event loop, while the QMainWindow object is the main window of the application.

This is a simple code to create your first GUI Window with PySide6:

import sys
from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication(sys.argv)

window = QMainWindow()
window.show()

sys.exit(app.exec())

import sys

from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication(sys.argv)

window = QMainWindow()

window.show()

sys.exit(app.exec())

In the above code we first imported the necessary modules from PySide6. after that we have created QApplication object and QMainWindow object. The QMainWindow object is assigned to the window variable.

Finally, we call the show() method to display the window and the sys.exit() method to start the application’s event loop.

Run the complete code and this will be the result.

Customizing the Window

Now that we have created basic window we can customize it according to our needs. we can add widgets such as buttons, labels, and text boxes, and also we can modify the window’s appearance by changing its size, title, and background color.

This is the code that demonstrates how to change the window’s title and size:

import sys
from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication(sys.argv)

window = QMainWindow()
window.setWindowTitle("My First PySide6 Window")
window.setGeometry(100, 100, 500, 500)
window.show()

sys.exit(app.exec())

import sys

from PySide6.QtWidgets import QApplication, QMainWindow

app = QApplication(sys.argv)

window = QMainWindow()

window.setWindowTitle("My First PySide6 Window")

window.setGeometry(100, 100, 500, 500)

window.show()

sys.exit(app.exec())

In the above code, we have added two new lines. The first line sets the window’s title to “My First PySide6 Window,” and the second line sets the window’s geometry to (100, 100, 500, 500), which specifies the window’s position on the screen (100 pixels from the left and 100 pixels from the top) and its size (500 pixels wide and 500 pixels high).

Final Thoughts

In this article we have provided brief introduction to PySide6 and demonstrated how to create basic window using PySide6. We have also shown how you can customize window’s appearance and add widgets to it. with PySide6 you can create powerful and beautiful desktop applications that are compatible with multiple operating systems.
