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.

Setup


The MySQL database will need to be configured to let you have remote access to it. Let's look at how we can do this:

  1. You will need to have the server and/or client installed.
  2. Then, we'll create the database and make it accessible from the network, if needed. This will be done using the command line and a Terminal application.

The MySQL server

I am using Ubuntu, so these commands will be mostly specific to a Debian-based Linux. If you are using a different Linux distribution, only the installation command would be different. You should install the MySQL server and client according to your distribution. The commands to create the database would be the same.

Here's how we will set up the server:

  1. You will need the MySQL server and client installed:

sudo apt-get install mysql-server mysql-client

  1. Run sudo mysql_secure_installation, which will allow you to set up the root account. Then, log in to the mysql root account:

sudo mysql -u root -p

  1. Create a new database username and passwordGRANT ALL PRIVILEGES...
