Anatomy of real world apps, Qt Quick and C++
summary
Shows a concrete architecture: QML front end with C++ backend, lists implemented as abstract item models not object arrays, and navigation driven by a QStateMachine-driven UI (14 states in the demo) exposed to QML via an isActive flag. Demonstrates two deployed music clients (WIMP/Urørt) and explains loaders, a centralized theme object for sizes and pixmaps, and platform gotchas (rotation and the E6 form factor). Code snippets and tradeoffs are shown and the examples are working apps.
