Game Programming Using Qt: Beginner's Guide

By: Lorenz Haas, Witold Wysota, Witold Wysota, Lorenz Haas

Overview of this book

Qt is the leading cross-platform toolkit for all significant desktop, mobile, and embedded platforms and is becoming more popular by the day, especially on mobile and embedded devices. Despite its simplicity, it's a powerful tool that perfectly fits game developers’ needs. Using Qt and Qt Quick, it is easy to build fun games or shiny user interfaces. You only need to create your game once and deploy it on all major platforms like iOS, Android, and WinRT without changing a single source file. The book begins with a brief introduction to creating an application and preparing a working environment for both desktop and mobile platforms. It then dives deeper into the basics of creating graphical interfaces and Qt core concepts of data processing and display before you try creating a game. As you progress through the chapters, you’ll learn to enrich your games by implementing network connectivity and employing scripting. We then delve into Qt Quick, OpenGL, and various other tools to add game logic, design animation, add game physics, and build astonishing UI for the games. Towards the final chapters, you’ll learn to exploit mobile device features such as accelerators and sensors to build engaging user experiences. If you are planning to learn about Qt and its associated toolsets to build apps and games, this book is a must have.

Clear their text property so that they don't display anything. Then, drag Widget from the widget box, drop it between the two labels' and set its object name to gameBoard. Invoke the context menu on the widget that you just dropped and choose Promote to. This allows us to substitute a widget in the form with another class; in our case, we will want to replace the empty widget with our game board. Fill the dialog that has just appeared with the values shown in the following figure:

Then, click on the button labeled Add and then Promote to close the dialog and confirm the promotion. You will not notice any changes in the form because the replacement only takes place during compilation. Now, apply a vertical layout on the form...
