[Interest] SingletonType functions not visible in QML

[Dmitry Volosnykh]

Samuel, what you ask is explained here:
http://doc.qt.io/qt-5/qqmlengine.html#qmlRegisterSingletonType-2

citation:

NOTE: A QObject singleton type instance returned from a singleton type
provider is owned by the QML engine. For this reason, the singleton type
provider function should not be implemented as a singleton factory.
