KDBindings

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.

Using KDBindings

KDBindings requires a C++ compiler with C++17 support.

Compatibility with Qt

Because Qt defines emit as a keyword, Qt is by default incompatible with KDBindings, which uses emit as a function name.

This can only be fixed by defining QT_NO_EMIT or QT_NO_KEYWORDS and simply omitting emit in your Qt code.

To make this easy, KDBindings includes a CMake option: KDBindings_QT_NO_EMIT, which defines this for all dependents of KDBindings.
