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.

Hello World!

In this chapter, we will learn how to use OpenGL 3 with Qt 6. Common OpenGL functions such as glBegin, glVertex2f, glColor3f, glMatrixMode, and glLoadIdentity have all been removed from OpenGL 3. OpenGL 3 uses vertex buffer objects (VBOs) to send data to the GPU in batches instead of sending them one by one through functions such as glVertex2f(), which slows down the rendering while waiting for the CPU to submit the data one by one. Therefore, we will pack all of the data into VBOs and send it all in one huge package to the GPU and instruct the GPU to calculate the resulting pixels through shader programming. We will also be learning how to create simple shader programs through a C-like programming language called OpenGL Shading Language (GLSL).

How to do it…

Let’s get started by following these steps:

  1. We will create a new class called RenderWindow, which inherits from the QOpenGLWindow class. Go to File | New File, then select C++ Class under...
