Project Structure

In this chapter, we will create a new multiproject solution that will be the foundation of our example application. We will apply a Model View Controller pattern, separating the user interface and business logic. We will also introduce Qt’s unit testing framework—QtTest—and demonstrate how to integrate it into our solution. We will cover these things in this chapter:

Projects, MVC, and unit testing
Creating a library project
Creating a unit tests project
Creating a user interface project
Mastering MVC
The QObject base class
QML
Controlling project output

Key benefits

• A practical guide on the fundamentals of application development with QT 5

• Learn to write scalable, robust and adaptable C++ code with QT

• Deploy your application on different platforms such as Windows, Mac OS, and Linux

Description

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.

This is an extremely well written Qt 5 book. It does NOT cover C++, but serves as a pedagogical guide to help you off the ground to start Qt programming using QML and a illustrative sample project from the beginning to the end. It is not exhaustive, but includes all the necessary points you would need to get a jump start.The author writes really well. Beyond the technical contents, the writing itself is very enjoyable to read. The book itself is also a very good example of what technical writing should be.

Following the author's explanations and the code examples provided from the website, it is hard to get lost in this book. The formula of concept->plan->code->explanation is well done here, and the code ran smoothly throughout the book. Halfway through chapter 5 I felt confident enough to "split" from the book example of a client management system and create a system for inputting CCG matches. While these two systems are very similar, all the differences I encountered were remedied by the author's in-depth explanations of the underlying Qt concepts.The only time my program majorly blew up was during the object factory part of chapter 9. The primary way I solved it was by religiously following the code examples. For this though, I blame my lackluster C++ skills. I also had difficulty getting the RSS feed to work properly on any website that wasn't the book example one.TLDR; Well-written book for learning Qt framework -- especially QML. Shore up on your C++ skills. Follow provided code examples if you get really stuck.

I have been a programmer in the Microsoft world for a long time and have been wondering about going over to the other side. This book made the conversion super easy and I think I am going to stay with it.I am delightedFor anyone who has some experience with other methods, this book is super easy to follow and you'll be a C++ programmer in no time at all.

Very good book for those, who would like to make UI Applications using Qt. You dont need to have previous knowledge about QML, however definetely have to have some Qt and C++ techniques. You start to develop an together with author step by step. The first four chapter makes a very good introduction to QML. Then you start dealing with data with data, JSON Serialization and saving them into SQL. If you have couple of years experience with Qt, I suggest it.

If you wanna dabble with Qt Quick (QML), then this book is a MUST!I doesn't cover Qt Widgets at all, and that's all good! I wanted a book focusing on Qt Quick (QML) and I found it!So many valuable tips and tricks! The project you build throughout the book is sooooooo good. You'll learn A LOT!Covers QML <-> C++ integration, building libraries, Qt Testing, and so much more.Worth every penny!
