PyQt5 has long been the most powerful and comprehensive GUI framework available for Python, yet there is a lack of cohesive resources available to teach Python programmers how to use it. This book aims to remedy the problem by providing comprehensive coverage of GUI development with PyQt5. This book covers the following exciting features: - Get to grips with the inner workings of PyQt5 - Learn how elements in a GUI application communicate with signals and slots - Learn techniques for styling an application - Explore database-driven applications with the QtSQL module - Create 2D graphics with QPainter - Delve into 3D graphics with QOpenGLWidget - Build network and web-aware applications with QtNetwork and QtWebEngine If you feel this book is for you, get your [copy](https://www.amazon.com/dp/1-789-61290-X) today! <a href="https://www.packtpub.com/?utm_source=github&utm_medium=banner&utm_campaign=GitHubBanner"><img src="https://raw.githubusercontent.com/PacktPublishing/GitHub/master/GitHub.png" alt="https://www.packtpub.com/" border="5" /></a> ## Instructions and Navigations All of the code is organized into folders. For example, Chapter03. The code will look like the following: ``` # inside __init__() self.goodbutton = qtw.QPushButton("Good") self.layout().addWidget(self.goodbutton) self.goodbutton.clicked.connect(self.no_args) # ... def no_args(self): print('I need no arguments') ``` **Following is what you need for this book:** This book is for programmers who want to create attractive, functional, and powerful GUIs using the Python language. You’ll also find this book useful if you are a student, professional, or anyone who wants to start exploring GUIs or take your skills to the next level. Although prior knowledge of the Python language is assumed, experience with PyQt, Qt, or GUI programming is not required. With the following software and hardware list you can run all code files present in the book (Chapter 1-17). ### Software and Hardware List | Chapter | Software required | OS required | | -------- | ------------------------------------ | ----------------------------------- | | 1 - 17 | Python 3.7 or greater, PyQt 5.12 | Windows, Mac OS X, and Linux (Any) | | 17 | PyInstaller 3.4, SetupTools 41.0.1 | Windows, Mac OS X, and Linux (Any) | | 1-4 | QtDesigner/QtCreator 4.8.0 or higher | Windows, Mac OS X, and Linux (Any) | | 9 | SQLite 3 | Windows, Mac OS X, and Linux (Any) | | 12, 14 | psutil 5.6.2 | Windows, Mac OS X, and Linux (Any) | | 15 | Raspberry Pi 3B+, Raspbian 10 | Windows, Mac OS X, and Linux (Any) | We also provide a PDF file that has color images of the screenshots/diagrams used in this book.
