Hands-On GUI Programming with C++ and Qt5

By: Lee Zhi Eng

Overview of this book

Qt 5, the latest version of Qt, enables you to develop applications with complex user interfaces for multiple targets. It provides you with faster and smarter ways to create modern UIs and applications for multiple platforms. This book will teach you to design and build graphical user interfaces that are functional, appealing, and user-friendly. In the initial part of the book, you will learn what Qt 5 is and what you can do with it. You will explore the Qt Designer, discover the different types of widgets generally used in Qt 5, and then connect your application to the database to perform dynamic operations. Next, you will be introduced to Qt 5 chart which allows you to easily render different types of graphs and charts and incorporate List View Widgets in your application. You will also work with various Qt modules, like QtLocation, QtWebEngine, and the networking module through the course of the book. Finally, we will focus on cross-platform development with QT 5 that enables you to code once and run it everywhere, including mobile platforms. By the end of this book, you will have successfully learned about high-end GUI applications and will be capable of building many more powerful, cross-platform applications.

The Qt networking module

In the following section, we will learn about the Qt networking module and how it can help us to achieve server-client communication via the TCP or UDP connection protocols.

Connection protocols

The networking module in Qt is the module that offers both low-level networking functionality, such as TCP and UDP sockets, as well as high-level networking classes for web integration and network communication.

In this chapter, we will use the TCP (Transmission Control Protocol) internet protocol for our program instead of the UDP (User Datagram Protocol) protocol. The main difference is that TCP is a connection-oriented protocol that requires all clients to establish a connection to the server before they...
