Reactive programming & data binding in C++

From plain C++ you get:

  • Signals + Slots.
  • Properties templated on the contained type.
  • Property bindings allowing reactive code to be written without having to do all the low-level, error prone plumbing by hand.
  • Lazy evaluation of property bindings.
  • No more broken bindings.
  • Totally stand-alone "header-only" library. No heavy Qt dependency.
  • Can still be used with Qt if you so wish.
