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 Creator IDE and what it can be used for. Qt Creator is an IDE with a great set of tools. It helps you to easily create great GUI applications for multiple platforms. Developers don't need to write lengthy code just to create a simple button or change a lot of code just to align a text label – Qt Designer automatically generates code for us when we design our GUI. We created a GUI application with just a few clicks, and we also learned about the various advanced options available in the IDE, including how to manage kits and shortcuts. The built-in Qt Assistant provides great help with useful examples and can help us with our own documentation.

In the next chapter, we will discuss GUI design using Qt Widgets. Here, you will learn about different widgets, how to create your own GUI element, and how to create a custom GUI application.
