def add_task(self): task = self.input_field.text().strip() if task: self.task_list.addItem(task) self.input_field.clear() else: QMessageBox.warning(self, "Warning", "Task cannot be empty.")

if == " main ": app = QApplication(sys.argv) window = TodoApp() window.show() sys.exit(app.exec())

Once you have a window open, you'll want to explore these advanced features that elevate your apps from basic scripts to professional software:

Here's a simple "Hello, World!" application using PyQt6:

button = QPushButton("Click Me", window) button.setGeometry(50, 50, 100, 30) # x, y, width, height

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.

This paper provides a ready-to-use tutorial for beginners and intermediate Python developers. Each code block is executable and demonstrates a standalone concept.
