import sys from PyQt6.QtWidgets import QApplication, QWidget, QLabel def main(): # 1. Create the application instance app = QApplication(sys.argv) # 2. Create a basic widget (the window) window = QWidget() window.setWindowTitle("My First PyQt6 App") window.resize(300, 200) # 3. Add a UI element label = QLabel("Hello, PyQt6!", parent=window) label.move(100, 80) # 4. Show the window and start the event loop window.show() sys.exit(app.exec()) if __name__ == "__main__": main() Use code with caution. 3. Core Concepts: Signals and Slots
PyQt6 uses a signal-slot mechanism to connect widgets and handle events. A signal is emitted when a widget performs an action, and a slot is a function that responds to the signal.

Layouts automatically arrange widgets; avoid fixed geometry. import sys from PyQt6

PyQt6 is a set of Python bindings for the Qt6 application framework, enabling developers to create cross-platform desktop applications with native look and feel. This paper provides a structured tutorial on PyQt6, covering installation, fundamental concepts (signals, slots, widgets, layouts), event handling, and practical application development. By the end, readers will be able to build functional GUI applications.
Here's a simple "Hello, World!" application using PyQt6: Add a UI element label = QLabel("Hello, PyQt6
import sys from PyQt6.QtWidgets import QApplication, QWidget
app = QApplication(sys.argv) # Create application object window = QWidget() # Create main window window.setWindowTitle("My First PyQt6 App") window.resize(400, 300) window.show() # Display window
