Learn Qt 5

Overview of this book

Qt is a mature and powerful framework for delivering sophisticated applications across a multitude of platforms. It has a rich history in the Linux world, is widely used in embedded devices, and has made great strides in the Mobile arena over the past few years. However, in the Microsoft Windows and Apple Mac OS X worlds, the dominance of C#/.NET and Objective-C/Cocoa means that Qt is often overlooked. This book demonstrates the power and flexibility of the Qt framework for desktop application development and shows how you can write your application once and deploy it to multiple operating systems. Build a complete real-world line of business (LOB) solution from scratch, with distinct C++ library, QML user interface, and QtTest-driven unit-test projects. This is a suite of essential techniques that cover the core requirements for most LOB applications and will empower you to progress from a blank page to shipped application.

Projects, MVC, and unit testing

The scratchpad application we built in the previous chapter is a Qt project, represented by a .pro file. In a business environment, technical solutions are generally developed as part of company initiatives, and these initiatives are generally also called projects. To try and minimize confusion (and the number of times the word project appears!), we’ll use project to mean a Qt project defined by a .pro file and the word initiative to refer to projects in the business sense.

The initiative we will work on will be a generic client management system. It will be something that can be tweaked and re purposed for multiple applications—for a supplier managing customers, a health service managing patients, and so on. It will perform common tasks found over and over in real-world Line of Business (LOB) applications, principally adding, editing...
