Qt Quick Best Practices and Design Patterns
summary
Open-source Qt Media Hub (an XBMC clone) shows QML for presentation and C++ as the runtime: keep business logic and models in C++, expose types with qmlRegisterType not context properties, prefer typed Q_PROPERTY with notify and avoid QVariant, use QDeclarativeListProperty for mutable lists, implement one-time init in componentComplete via QDeclarativeParserStatus, share stateless JS with pragma library, control image memory with sourceSize, and favor many small QML components over huge files.
