Mastering Qt 5

3.1 (8)
By: Guillaume Lazar, Robin Penea

Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

/path/to/qt/installation/5.7/gcc_64/bin/qmake -makefile -o Makefile /path/to/sysinfoproject/ch02-sysinfo.pro

This command will execute qmake in the -makefile mode to generate a Makefile based on your sysinfo.pro file. If you skim through the Makefile content, you will see many things we covered earlier in the .pro section, such as the link to Qt modules, headers of...
