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.

The menu should open now and you can drag the action so that a red bar appears in the submenu in the position where you want the menu entry to appear—now you can release the mouse button to create the entry. Afterwards, open the menu again by clicking on File and choose Add Separator. Then, repeat the drag-and-drop operation for the Quit action to insert a menu entry for it just below the separator in the File menu, as shown in the following figure:

What just happened?

Using graphical tools, we created a menu for our program and added a number of actions (that were automatically transformed into menu items) to that menu. Each menu entry received some text and an icon specified by the action that was dropped in...
