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.

Summary

In this chapter, we made our application even more testable by introducing our first object factory. They are a really useful layer of abstraction that make unit testing so much easier, and on larger projects, it's common to end up with several factories. We then made our UI even more dynamic by having Style properties that can scale along with the Window. EnumeratorDecorators got some love and an editor component of their own, fully finger-friendly to boot. We then put that editor to use and implemented Contact management, showing how collections of objects can easily be viewed and edited.

With our application more fleshed out, we then took a look at how to get our shiny new work of genius into the hands of our end users. Different operating systems each have their own take on things, and you will undoubtedly discover quirks and encounter challenges in your own...
