This chapter laid the foundation for getting to know Qt and what it can be used for. Installing of Qt on macOS and Linux was outlined. A small hello world application was written and compiled, all from the command line, without any need for an IDE. This meant that we were also introduced to the various steps that lead to the final program.
Finally, the hello world application was modified to employ QSS in a bid to show what other things can be done to a widget.
In Chapter 2, Creating Widgets and Layouts, we will explore more widgets in Qt and how to organize and group them.
