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.

Rendering a 2D canvas in QML

In all the previous examples of this chapter, we have discussed the methods and techniques used to render 2D graphics with Qt’s C++ API. However, we have yet to learn how to achieve similar results using the powerful QML script.

How to do it…

In this project, we’ll be doing something quite different:

  1. As usual, the first step is to create a new project by going to File | New File or Project and selecting Qt Quick Application as the project template:

  1. Once you are done creating the new project, open up main.qml, which is listed under qml.qrc in the project pane. After that, set an ID for the window and adjust its width and height values to larger values, like so:
    import QtQuick
    import QtQuick.Window
    Window {
        id: myWindow
        visible: true
        width: 640
     ...
