Introduction to Qt 5 for Cross-Platform Application Development

Learn how to develop graphical user interface (GUI) applications using the key concepts of the Qt framework with this practical guide.

Starting with the basics, you will gain an understanding of how to write, assemble, and build Qt applications from the command line. You will also learn about key concepts like Signals and Slots in Qt, and discover best practices and effective techniques for designing graphical user interfaces using Qt 5.

Qt is a popular cross-platform application framework and widget toolkit used to create GUI applications for different hardware and operating systems. This book aims to introduce readers to Qt with simple, practical examples that focus on building blocks rather than theory.

With Qt installation and setup covered, you will learn to create your first application and explore Widgets, Qt's interface building blocks. The core concept of signals and slots is thoroughly illustrated through examples, along with creating custom widgets, signals, slots, and communicating information via dialog boxes. The book also covers writing applications that can connect to databases to persist data.

By the end of the book, you will be equipped to start creating your own Qt applications and have the confidence to delve into more advanced techniques and materials to further develop your skills.

Key topics covered in this book include: - Setting up and configuring your machine to begin developing Qt applications - Exploring different widgets and layouts for constructing UIs - Understanding the key concept of signals and slots and how they animate a GUI - Creating customized widgets with signals and slots - Subclassing and creating custom windows applications - Writing database-connected applications

This book is suitable for anyone looking to start development of graphical user interface applications, regardless of prior exposure to other toolkits. However, basic knowledge of C++ and Object Oriented Programming is recommended. Familiarity with GNU/Linux is also beneficial, although not required.
