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.

Building with qmake

Make is a build tool that reads project configuration file called a Makefile and builds executable programs and libraries. qmake is a Qt-provided build tool that simplifies the build process for development projects across multiple platforms. It expands the information in each project file to a Makefile that executes the necessary commands for compiling and linking. It can also be used for non-Qt projects. qmake generates a Makefile based on the information in a project file, and contains supplementary features to support development with Qt, automatically including build rules for moc and uic. qmake can also create projects for Microsoft Visual Studio without requiring the developer to change the project file.

Being a community-driven framework, Qt is really flexible toward developers and gives them the freedom to choose the most suitable tools for their project, without forcing them to use its own build system. Qt supports the following types of build systems...
