Chapter 11. Having Fun with Serialization
The previous chapter was a firework of threads, sockets, and workers. We hope that your minions have been working hard. In this chapter, we will turn our attention to the serialization with Qt. You will learn how to serialize data in multiple formats with a flexible system. The example project will be a virtual drum machine, in which you can compose you own drum beat, record it, play it, save it, and load it back. Your drum beat will be probably so awesome that you will want to share it: you will now be able to do it in various formats.
This chapter will cover the following topics:
- How to architecture an application that plays and records sounds
- The
QVariantclass and its inner mechanics - A flexible serialization system
- JSON serialization
- XML serialization
- Binary serialization
- The Qt Multimedia framework
- Drag and drop handling with Qt
- Triggering a button from your keyboard
