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

Questions

In the following, you will find the last set of questions to test your understanding of the topics discussed in this chapter:

  1. Why would you like to test a Qt application?
  2. How would you implement a performance regression test measuring the FPS rate of a QML application?
  3. Do you have any ideas about deploying a Qt application to embedded Linux? Take some hints from the previous chapter.
  4. You are running automated GUI tests—what problems could arise? What could be done to prevent them?
  5. What does TDD mean?
  6. How does Squish identify GUI elements? Can you figure it out?
  7. Which deployment type is better—a static or a dynamic build?
  8. Is performance optimization in Qt black magic? Be honest!
