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.

Time for action – creating a Qt Script editor

Let's do a simple exercise and create a graphical editor to write and execute scripts. Start by creating a new GUI project and implement a main window composed of two plain text edit widgets (ui->codeEditor and ui->logWindow) that are separated using a vertical splitter. One of the edit boxes will be used as an editor to input code and the other will be used as a console to display script results. Then, add a menu and toolbar to the window and create actions to open (ui->actionOpen) and save (ui->actionSave) the document, create a new document (ui->actionNew), execute the script (ui->actionExecute), and to quit the application (ui->actionQuit). Remember to add them to the menu and toolbar. As a result, you should receive a window similar to the one shown in the following screenshot:

Connect the quit action to the QApplication::quit() slot. Then, create an openDocument() slot and connect it to the appropriate action. In the...
