Overview of this book

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Designing a maintainable project


The first step in designing a maintainable project is to properly split it in clearly defined modules. A common approach is to separate the engine from the user interface. This separation forces you to reduce coupling between the different parts of your code and make it more modular.

This is exactly the approach we will take with the gallery application. The project will be divided into three sub-projects:

The sub-projects are as follows:

  • gallery-core: This is a library containing the core of the application logic: the data classes (or business classes), persistent storage (in SQL), and the model that makes the storage available to the UI through a single entry point.

  • gallery-desktop: This is a Qt widgets application that will depend on the gallery-core library to retrieve data and display it to the user. This project will be covered in Chapter 4Conquering the Desktop UI.

  • gallery-mobile: This is a QML application targeted at mobile platforms (Android and iOS...
