+.. py:function:: qmlRegisterUncreatableType(pytype: type, uri: str, versionMajor: int, versionMinor: int, qmlName: str, noCreationReason: 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 qmlName: name exposed to QML
+   :param str noCreationReason: Error message shown when trying to create the QML type
+   :return: int (the QML type id)
+
+   This function registers the Python *type* in the QML system as an uncreatable type with the
+   name *qmlName*, in the library imported from *uri* having the
+   version number composed from *versionMajor* and *versionMinor*,
+   showing *noCreationReason* as an error message when creating the type is attempted.
+
+   For example, this registers a Python class 'MySliderItem' as a QML
+   type named 'Slider' for version '1.0' of a module called
+   'com.mycompany.qmlcomponents':
+
+   ::
+       qmlRegisterUncreatableType(MySliderItem, "com.mycompany.qmlcomponents", 1, 0, "Slider", "Slider cannot be created.")
+
+   Note that it's perfectly reasonable for a library to register types
+   to older versions than the actual version of the library.
+   Indeed, it is normal for the new library to allow QML written to
+   previous versions to continue to work, even if more advanced
+   versions of some of its types are available.
