Overview of this book

With the growing need to develop GUIs for multiple targets and multiple screens, improving the visual quality of your application has become pivotal in helping it stand out from your competitors. With its cross-platform ability and the latest UI paradigms, Qt makes it possible to build intuitive, interactive, and user-friendly UIs for your applications. The third edition of Qt 6 C++ GUI Programming Cookbook teaches you how to develop functional and appealing UIs using the latest version of Qt 6 and C++. This book will help you learn a variety of topics such as GUI customization and animation, graphics rendering, and implementing Google Maps. You’ll also be taken through advanced concepts such as asynchronous programming, event handling using signals and slots, network programming, and other aspects to optimize your application. By the end of this Qt book, you’ll have the confidence you need to design and customize GUI applications that meet your clients' expectations and have an understanding of best-practice solutions to common problems during the app development process.

  2. Open up your project file (.pro) and add the OpenGL module to your project by adding an opengl keyword behind QT +=; after that, run qmake to reload the project modules:
    QT += core gui opengl
  3. You also need to add another line in your project file so that it will load both the OpenGL and OpenGL Utilities (GLU) libraries during startup. Without these two libraries, your program will not be able to run:
    LIBS += -lopengl32 -lglu32
  4. Open up main.cpp and replace mainwindow.h with the QtOpenGL header:
    #include <QtOpenGL>
  5. Remove all of the code related to the MainWindow class from your main.cpp file and replace it with the code...
