Beginner Python GUI using PySide6

Creating graphical user interfaces (GUIs) in Python can be a daunting task for beginners, but with the help of PySide6, it can be relatively easy. PySide6 is a Python binding to the Qt framework, which allows you to create native and cross-platform GUI applications with ease.

Setting up PySide6

To get started with PySide6, you first need to install it using pip:

pip install PySide6

Once you have installed PySide6, you can start creating your first GUI application.

Creating a simple GUI application

Let’s create a simple GUI application that displays a basic window with a label.

from PySide6.QtWidgets import QApplication, QLabel

app = QApplication([])

label = QLabel("Hello, World!")
label.show()

app.exec()

This code creates an instance of the QApplication class, then creates a QLabel widget with the text “Hello, World!” and displays it on the screen. Finally, the app.exec() method starts the application event loop.

Adding interactivity to your GUI

You can also add interactivity to your GUI applications by connecting signals and slots. Signals are emitted when a user interacts with a widget, while slots are functions that are called in response to a signal.

Here’s an example of how you can connect a button click signal to a slot that changes the text of a label:

from PySide6.QtWidgets import QApplication, QLabel, QPushButton, QVBoxLayout, QWidget

app = QApplication([])

widget = QWidget()
layout = QVBoxLayout()

label = QLabel("Hello, World!")
button = QPushButton("Click me!")

layout.addWidget(label)
layout.addWidget(button)

widget.setLayout(layout)
widget.show()

def on_button_click():
    label.setText("Button clicked!")

button.clicked.connect(on_button_click)

app.exec()

This code creates a button that, when clicked, changes the text of the label to “Button clicked!”.

Conclusion

Creating GUI applications in Python using PySide6 doesn’t have to be difficult, even for beginners. By following these simple examples, you can start building your own GUI applications with ease.
