Cross-Platform Development with Qt 6 and Modern C++

By: Nibedit Dey

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.

Integrating with Google's C++ testing framework

GoogleTest is a testing and mocking framework developed by Google. The GoogleMock project has been merged into GoogleTest. GoogleTest requires a compiler that supports at least C++11 standards. It is a cross-platform test framework and it supports major desktop platforms such as Windows, Linux, and macOS. It helps you write better C++ tests with advanced features such as mocking. You can integrate Qt Test with GoogleTest to get the best of both frameworks. If you intend to use both testing framework features, then you should use GoogleTest as the primary testing framework and inside the test cases, you can use Qt Test's features.

Qt Creator has built-in support for GoogleTest. You can find the Google Test tab in the Testing section on the Options screen and set your global GoogleTest preferences as shown in Figure 9.10:
