The QML_DECLARE_PROPERTIES() macro is used to specify the properties, and the -// QML_DEFINE_PROPERTIES() macro to register the properties with the -// QQmlAccessorProperties singleton. -// -// A class with accessor properties must also add the Q_CLASSINFO("qt_HasQmlAccessors", "true") -// tag to its declaration.

As QML_DEFINE_PROPERTIES() is idempotent, it is -// recommended to call it in the type's constructor as well as when the type is registered -// as a QML element (if it ever is).
