In this chapter, you learned a number of core Qt technologies ranging from text manipulation, to accessing devices that can be used to transfer or store data using a number of popular technologies such as XML or JSON. You should be aware that we have barely scratched the surface of what Qt offers and there are many other interesting classes you should familiarize yourself with but this minimum amount of information should give you a head start and show you the direction to follow with your future research.
In the next chapter, we will switch from describing data manipulation, which can be visualized using text or only in your imagination, to a more appealing media. We will start talking about graphics and how to transfer what you can see in your imagination to the screen of your computer.
