Summary
In this chapter, we learned about using graphics with Qt. You should be aware we have only scratched the surface of Qt capabilities in this regard. What was presented in this chapter will let you implement custom widgets, do some basic painting on images, and render OpenGL scenes. There are many more functionalities that we didn't go through, such as composition modes, paths, SVG handling, and many others. We will come back to some of these features in subsequent chapters, but we will leave most for you to discover on your own.
In the next chapter, we will learn a more object-oriented approach to do graphics, called Graphics View.
