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.

Data models

Now that we have the infrastructure in place to be able to define data objects (entities and entity collections) and properties of various types (data decorators), we can move on and build the object hierarchy we laid out earlier in the chapter.

Class

Purpose

Address

Represents a supply or billing address

Appointment

Represents an appointment with a client

Contact

Represents a method of contacting a client

We’ll start with the simplest of the models—the address.

address.h:

#ifndef ADDRESS_H
#define ADDRESS_H
#include <QObject>
#include <cm-lib_global.h> #include <data/string-decorator.h> #include <data/entity.h>
namespace cm { namespace models {
class CMLIBSHARED_EXPORT...
