Summary
In this chapter, we learned how Qt provides the QPaintDevice interface and QPainter class to perform graphics operations. Using QPaintDevice subclasses such as QWidget, QImage, and QPixmap, you can perform onscreen and offscreen drawing. We also saw how Qt provides a separate viewable object hierarchy for large numbers of lightweight objects through the Graphics Scene Framework, supported by the classes QGraphicsView and QGraphicsScene and the QGraphicsItem interface.
In the next chapter, we turn from Qt's support for GUIs in C++ to that of Qt Quick. We'll learn about the fundamental Qt Quick constructs, performing animations and other transitions in Qt Quick, and how to integrate Qt Quick with a C++ application.
