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.")

def mousePressEvent(self, event): print(f"Mouse click at (event.x(), event.y())") This example combines signals, slots, layouts, and widgets.

from PyQt6.QtWidgets import QVBoxLayout layout = QVBoxLayout() layout.addWidget(button1) layout.addWidget(button2) window.setLayout(layout) Override event handlers in a subclass of QWidget : pyqt6 tutorial

# Signals self.add_button.clicked.connect(self.add_task) self.delete_button.clicked.connect(self.delete_task)

main_layout = QVBoxLayout() main_layout.addLayout(input_layout) main_layout.addWidget(self.task_list) main_layout.addWidget(self.delete_button) def add_task(self): task = self

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

Abstract 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. 1. Introduction Qt is a powerful C++ framework for GUI development. PyQt6, developed by Riverbank Computing, allows Python programmers to harness Qt’s capabilities. Compared to Tkinter, PyQt6 offers more widgets, better styling (QSS), and advanced features like OpenGL integration, multimedia, and networking.
