Hands-On Mobile and Embedded Development with Qt 5

By: Lorn Potter

Overview of this book

Qt is a world-class framework, helping you to develop rich graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. The framework helps you connect the dots across platforms and between online and physical experience. This book will help you leverage the fully-featured Qt framework and its modular cross-platform library classes and intuitive APIs to develop applications for mobile, IoT, and industrial embedded systems. Considerations such as screen size, device orientation changes, and small memory will be discussed. We will focus on various core aspects of embedded and mobile systems, such as connectivity, networking, and sensors; there is no IoT without sensors. You will learn how to quickly design a flexible, fast, and responsive UI that looks great. Going further, you will implement different elements in a matter of minutes and synchronize the UI elements with the 3D assets with high precision. You will learn how to create high-performance embedded systems with 3D/2D user interfaces, and deploy and test on your target hardware. The book will explore several new features, including Qt for WebAssembly. At the end of this book, you will learn about creating a full software stack for embedded Linux systems using Yocto and Boot to Qt for Device Creation.

Summary


Qt Quick is ready-made for using on mobile and embedded devices. From the simple building blocks of basic Qt Quick items to 3D data charts, you can write complicated animated applications using various data sets and presentations in QML.

You should now be able to use basic components such as Rectangle or Text to create Qt Quick applications that use dynamic variable bindings and signals.

We also covered how to use anchors to position the components visually and will be able to accept changing orientations and various screen sizes of target devices.

You are now able to use more conventional-looking components such as ready-made Button, Menu and ProgressBar instances, as well as more advanced graphical elements such as PieChart and BarChart.

 

We also examined using different animation methods available in Qt Quick, such as ProperyAnimation and NumberAnimation.

In the next chapter, we will learn about using particles and special graphical effects.
