Application Development with Qt Creator - Third Edition

By: Lee Zhi Eng, Ray Rischpater

Overview of this book

Qt is a powerful development framework that serves as a complete toolset for building cross-platform applications, helping you reduce development time and improve productivity. Completely revised and updated to cover C++17 and the latest developments in Qt 5.12, this comprehensive guide is the third edition of Application Development with Qt Creator. You'll start by designing a user interface using Qt Designer and learn how to instantiate custom messages, forms, and dialogues. You'll then understand Qt's support for multithreading, a key tool for making applications responsive, and the use of Qt's Model-View-Controller (MVC) to display data and content. As you advance, you'll learn to draw images on screen using Graphics View Framework and create custom widgets that interoperate with Qt Widgets. This Qt programming book takes you through Qt Creator's latest features, such as Qt Quick Controls 2, enhanced CMake support, a new graphical editor for SCXML, and a model editor. You'll even work with multimedia and sensors using Qt Quick, and finally develop applications for mobile, IoT, and embedded devices using Qt Creator. By the end of this Qt book, you'll be able to create your own cross-platform applications from scratch using Qt Creator and the C++ programming language.

Getting lost and found again – debugging

Qt Creator has a state-of-the-art GUI that hooks into either the GNU Debugger (GDB), or Microsoft's command-line debugger, CDB, if you use Microsoft tools.

If you've installed Qt Creator on macOS, Linux, or the MinGW version of Qt Creator for Windows, you have everything you need to begin debugging your application. If you already have Microsoft Visual Studio installed and then installed a version of Qt Creator that uses Microsoft's compiler, you also need to install the Microsoft command-line debugger to use Qt Creator's debugging features. Here's how you can install the command-line debugger:

  1. Download the debugging tools for Windows, either from http://msdn.microsoft.com/en-us/windows/hardware/hh852365 if you are using the 32-bit version of the compiler and Qt Creator, or from http://msdn.microsoft.com...
