Reimplementing Signals, Slots, Properties and Bindings from Qt in pure C++17
summary
KDBindings implements signals, slots, properties and data bindings in pure C++17, shipping as a header-only library on GitHub and usable under the MIT license. It recreates Qt-style property bindings, adds deferred evaluation, and cuts boilerplate — a QCameraLens reimplementation shrinks from ~300 lines to ~50–100 while remaining functional in a real project. Limitations: not thread safe, heavier templates increase compile time, and some features (bidirectional bindings, mutable property access) are planned.
