In this chapter, we have looked at a number of widgets that are useful in creating GUI applications. The process of compilation remains the same. We also learned how to use layouts to present and arrange multiple widgets.
Up to this point, our application does not do anything. The QPushButton instances, when clicked, do nothing along with the other widgets that are action driven.
In the next chapter, we shall learn how to animate our application so that it responds to actions, thus making them useful.
