In this chapter, we learned the fundamentals of Qt, which included steps for how to create a Qt application. Then, we had a walk-through of both Qt Widgets and Qt Quick, and how to change the layout. Finally, we rounded off by covering an important concept about the mechanism of signals and slots.

In the next chapter, we will have a chance to put this knowledge into practice and get started on building a real-world, and of course cross-platform, Qt application.
