PySide6 Tutorial: Create Your First Application

Creating a Basic Window in PySide6

In PySide6, creating a basic window is one of the first steps in building a graphical user interface (GUI) application. A window serves as the main container for your application's user interface elements. In this guide, we'll walk you through the process of creating a simple window using PySide6 and explain essential terms along the way.

Terminology:

Before we begin, let's clarify some key terms:

1. Widget: A widget is a fundamental graphical element in your GUI. Examples include buttons, labels, text boxes, and windows themselves. Widgets are the building blocks of your user interface.
2. Main Window: The main window is the top-level container for your application's user interface. It typically contains the menu bar, toolbar, and central area where you place your widgets.
3. Layout: A layout is used to arrange widgets within a container (e.g., a window or a dialog) in a specific way. Common layouts include QVBoxLayout (vertical layout), QHBoxLayout (horizontal layout), and QGridLayout (grid layout).

Create the Main Window

from PySide6.QtWidgets import QApplication, QMainWindow
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Basic PySide6 Window")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec())
