Overview of this book

Qt is a cross-platform application development framework widely used for developing applications that can run on a wide range of hardware platforms with little to no change in the underlying codebase. If you have basic knowledge of C++ and want to build desktop or mobile applications with a modern graphical user interface (GUI), Qt is the right choice for you. Cross-Platform Development with Qt 6 and Modern C++ helps you understand why Qt is one of the favorite GUI frameworks adopted by industries worldwide, covering the essentials of programming GUI apps across a multitude of platforms using the standard C++17 and Qt 6 features. Starting with the fundamentals of the Qt framework, including the features offered by Qt Creator, this practical guide will show you how to create classic user interfaces using Qt Widgets and touch-friendly user interfaces using Qt Quick. As you advance, you'll explore the Qt Creator IDE for developing applications for multiple desktops as well as for embedded and mobile platforms. You will also learn advanced concepts about signals and slots. Finally, the book takes you through debugging and testing your app with Qt Creator IDE. By the end of this book, you'll be able to build cross-platform applications with a modern GUI along with the speed and power of native apps.

This chapter explained the fundamentals of the Qt Widgets module and how to create a custom UI. Here, you learned to design and build GUIs with Qt Designer. Traditional desktop applications are usually built with Qt Designer. Features such as custom widget plugins allow you to create and use your own widget collection with Qt Designer. We also discussed customizing the look and feel of your application with style sheets and styles, as well as looking at the uses of and differences between widgets, windows, and dialogs. Now, you can create a GUI application with your own custom widgets with extended functionalities and create your own themes for your desktop application.

In the next chapter, we will discuss QtQuick and QML. Here, you will learn about QtQuick controls, Qt Quick Designer, and how to build a custom QML application. We will also discuss an alternate option of using Qt Quick for GUI design rather than widgets.
