Hands-On High Performance Programming with Qt 5

Overview of this book

Achieving efficient code through performance tuning is one of the key challenges faced by many programmers. This book looks at Qt programming from a performance perspective. You'll explore the performance problems encountered when using the Qt framework and means and ways to resolve them and optimize performance. The book highlights performance improvements and new features released in Qt 5.9, Qt 5.11, and 5.12 (LTE). You'll master general computer performance best practices and tools, which can help you identify the reasons behind low performance, and the most common performance pitfalls experienced when using the Qt framework. In the following chapters, you’ll explore multithreading and asynchronous programming with C++ and Qt and learn the importance and efficient use of data structures. You'll also get the opportunity to work through techniques such as memory management and design guidelines, which are essential to improve application performance. Comprehensive sections that cover all these concepts will prepare you for gaining hands-on experience of some of Qt's most exciting application fields - the mobile and embedded development domains. By the end of this book, you'll be ready to build Qt applications that are more efficient, concurrent, and performance-oriented in nature

Summary

In this chapter, we first learned how to test a Qt application, starting with the classic unit tests, their integration in Qt Creator, GUI test automation with Squish, and ending with performance regression testing. Then we had a look at the Qt application deployment problem and learned the difference between static and dynamic builds, the deployment support tools Qt has to offer, and the specific case of Windows deployment and installation.

This is the last chapter of the book, and I hope you enjoyed the ride. Maybe we didn't go deep enough into many topics, but, first, this was an intermediate-level book, and, second, you cannot go deep into everything, as some chapters could be expanded into entire books of their own. Hopefully, you can now see somehow more clearly through the mists of Qt and performance lands, and maybe you have even started to appreciate...
