Cross-Platform Development with Qt 6 and Modern C++

By: Nibedit Dey

Overview of this book

Qt is a cross-platform application development framework widely used for developing applications that can run on a wide range of hardware platforms with little to no change in the underlying codebase. If you have basic knowledge of C++ and want to build desktop or mobile applications with a modern graphical user interface (GUI), Qt is the right choice for you. Cross-Platform Development with Qt 6 and Modern C++ helps you understand why Qt is one of the favorite GUI frameworks adopted by industries worldwide, covering the essentials of programming GUI apps across a multitude of platforms using the standard C++17 and Qt 6 features. Starting with the fundamentals of the Qt framework, including the features offered by Qt Creator, this practical guide will show you how to create classic user interfaces using Qt Widgets and touch-friendly user interfaces using Qt Quick. As you advance, you'll explore the Qt Creator IDE for developing applications for multiple desktops as well as for embedded and mobile platforms. You will also learn advanced concepts about signals and slots. Finally, the book takes you through debugging and testing your app with Qt Creator IDE. By the end of this book, you'll be able to build cross-platform applications with a modern GUI along with the speed and power of native apps.

Other Qt Creator analysis tools

In the earlier section, we discussed QML Profiler, but you may need to analyze your C++ and Qt Widgets code. Qt Creator provides integration with some of the famous analysis tools to help you analyze your Qt application. Some of the tools that come with Qt Creator are listed here:

  • Heob
  • Performance Analyzer
  • Valgrind
  • Clang Tools: Clang-Tidy and Clazy
  • Cppcheck
  • Chrome Trace Format (CTF) visualizer

Let's briefly discuss these tools and become familiar with them before getting into their documentation.

To use Heob, you first need to download and install it. Buffer overruns and memory leaks can be easily detected with Heob. It works by overriding the caller process's heap functions. An access violation is raised when a buffer overrun occurs, and stack traces of the offending code and buffer allocation are noted. You will find the stack traces when the application exits normally. It doesn't require any recompilation...
