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.

In this chapter, we will implement classes to handle the most critical part of any Line of Business application—the data. We will introduce self-aware data entities, which can automatically serialize to and from JavaScript Object Notation (JSON), a popular serialization format used a lot in web communications. We will create the core models we need for our application and wire them up to our UI for reading and writing via custom controls. We will cover the following topics:

  • JSON
  • Data decorators
  • Abstract data entities
  • Collections of data entities
  • Concrete data models
  • UI controls and data binding
