C++ Reactive Programming

An introduction to RxQt

The RxQt library is a public domain library written over the RxCpp library and makes it easy to program with Qt events and signals in a reactive manner. To understand the library, let us jump into an example so that we can track the mouse events and filter them using the observable supplied by the library. The library can be downloaded from the GitHub repository at https://github.com/tetsurom/rxqt:
