![]() ![]() Next, expand the selected version and you will see a secondary list of options. Let's select the latest and greatest (Qt 5.10 at the time of writing) and leave all the older versions unchecked. You can have multiple versions installed side by side. Your first decision is which version(s) of the Qt framework you want. You are then asked to select which components you wish to install. We will create a simple scratchpad application that we will use throughout the remainder of the book to demonstrate various techniques. In this chapter, we will install and configure the Qt framework and associated Integrated Development Environment ( IDE) Qt Creator. Finally, we will produce an installation package so that we can deploy our application onto other machines. We will reach out to the internet and consume an RSS feed. We will persist those data entities in a database and learn how to find and update them. We will build “self-aware” data entities that can serialize themselves to and from JSON. We will control every aspect of our project configuration and output with QMake, including platform detection and conditional expressions. We will cover building a modern, responsive user interface with QML and wiring it up to rich C++ classes. We will build a complete real-world line of business ( LOB) solution from scratch, with distinct library, user interface, and unit test projects. This book aims to demonstrate the power and flexibility of the Qt framework and show how you can write your application once and deploy it to multiple operating system desktops. However, in the Microsoft Windows and Apple Mac OS X worlds, the dominance of C#/.NET and Objective-C/Cocoa mean that Qt is often overlooked. It has also made great strides in the Mobile arena over the past several years. It also has a rich history in the Linux world, with KDE and Sailfish OS using it extensively and many apps in the stores being developed using Qt. It is widely used in embedded devices including TVs, satellite set-top boxes, medical equipment, car dashboards, and much more. Qt is a mature and powerful framework for delivering sophisticated applications across a multitude of platforms. ![]()
