After this chapter, you're expected to handle common tasks and write types of real-world applications. You'll get your own understanding of Qt Quick and traditional Qt.

QML has an unbeatable advantage of flexible UI design, which is even more obvious on mobile platforms. While the development part is nearing the end, in the next chapter we'll talk about how to support multiple languages.
