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.

Debugging in Qt

In software development, technical problems arise often. To address these issues, we must first identify and resolve all of them before releasing our application to the public to maintain quality and our reputation. Debugging is a technique for locating these underlying technological issues.

In the coming sections, we will discuss popular debugging techniques used by software engineers to ensure their software's stability and quality.

Debuggers supported by Qt

Qt supports several different types of debuggers. The debugger you use can vary depending on the platform and compiler you're using for your project. The following is a list of debuggers that are widely used with Qt:

  • GNU Symbolic Debugger (GDB) is a cross-platform debugger developed by the GNU Project.
  • Microsoft Console Debugger (CDB) is a debugger from Microsoft for Windows.
  • Low Level Virtual Machine Debugger (LLDB) is a cross-platform debugger developed by the LLVM Developer...
