The building blocks of QML, and how to use it with C++
summary
Explains concrete patterns: expose C++ singletons via register uncreatable type and expose constructible C++ classes via register creatable type, keep heavy list models in C++ not JavaScript, and restrict JS to event handlers. Advises splitting QML into small components (aim under 1,000 lines), use Loader to reduce load time, and watch for binding explosions that cause runtime slowdowns; recommends QML profilers because debugging is essentially printf-level. Notes deployment caveats (QML files editable by users unless compiled) and testing is harder than C++.
