In addition, 1) QList<QObject *>-typed Q_PROPERTIES can be directly bound as QML models. 2) QList<QObject *>-typed Q_PROPERTIES can be successfully accessed in QScriptEngine engine, provided qScriptRegister(Sequence)MetaType is used to register them. 3) QList<QObject *>-typed Q_PROPERTIES cannot be accessed in QML's JavaScript engine, since they are kept as QVariant(QList<QObject*>). Since QQmlEngine inherits QJSEngine, which provides no counterpart for qScriptRegisterMetaType, it is currently possible to register such custom type in QML's JavaScript engine ? Is QJSEngine intended to replace QScriptEngine in the future ?
