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.

Designing GUIs


So far, we have coded all the user interfaces manually by writing C++ code that instantiates widgets, arranges them in layouts, and connects signals to slots. It is not that hard for simple widgets, but becomes tedious and time-consuming when the UI becomes more and more complex. Fortunately, Qt provides tools to do all this in a more pleasant way. Instead of writing C++ code, we can create forms using a graphical tool by dragging and dropping widgets on a canvas, applying layouts to them, and even establishing signal-slot connections using the point-and-click technique. Later during the compilation, such forms will get converted into C++ code for us and will be ready for applying onto a widget.

The tool is called Qt Designer and is integrated with Qt Creator. To use it, select New File or Project from the File menu and choose the Qt Designer Form Class template available after selecting Qt in the Files and Classes section of the dialog box. You get to choose a template for...
