************************
.. py:function:: qmlRegisterSingletonType(pytype: type, uri: str, versionMajor: int, versionMinor: int, typeName: str) -> int
:param type pytype: Python class
:param str uri: uri to use while importing the component in QML
:param int versionMajor: major version
:param int versionMinor: minor version
:param str typeName: name exposed to QML
:return: int (the QML type id)
This function registers a Python type as a singleton in the QML system.

:param int versionMajor: major version
:param int versionMinor: minor version
:param str typeName: name exposed to QML
:param object callback: Python callable (to handle Python type)
:return: int (the QML type id)
This function registers a Python type as a singleton in the QML system using
the provided callback (which gets a QQmlEngine as a parameter) to generate
the singleton.
