C++ Reactive Programming

Event-driven programming under Qt

The Qt Framework is an industrial-strength, cross-platform, and multi-platform GUI toolkit that runs on Windows, GNU Linux, macOS X, and other Mac systems. The toolkit has been compiled into embedded systems and mobile devices. The C++ Programming model has leveraged something called Meta Object Compiler (MOC), which will peruse the source code for directives (a bunch of macros and language extensions embedded in the source code) and generate appropriate additional source code to generate event handlers. So, before the C++ compiler gets the source code, the MOC pass has to run to generate legal ANSI C++ by removing those extra linguistic constructs specific to the Qt system.
