Type driven user interfaces with Qt and C++
summary
C++17 templates define a central data schema that generates concrete code: command types, validators, storage_for-derived stores, persisted events, computation pipelines and view-model QObjects (not raw widgets). Implementation uses ADL plus a ptr trick and a storage_for pattern to recurse schema→code, and relies on templated QObjects via Verdigris with a constexpr registration API. Demo repository shows it working; tradeoffs are required template boilerplate, very long type names, no C++11 support and no off‑the‑shelf automatic generator.
