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.

Embedding Google maps in your project

In this recipe, we will learn how to embed Google maps in our project through Qt’s WebEngine module. This example doesn’t focus much on Qt and C++, but rather on the Google Maps API in HTML code.

    QT += core gui webenginewidgets
  3. Open mainwindow.ui and add a vertical layout to the canvas. Then, select the canvas and click the Lay Out Vertically button on top of the canvas. You will get the following:
