.. currentmodule:: PySide6.QtQml
.. _QmlUncreatable:
QmlUncreatable
**************
.. py:decorator:: QmlUncreatable
Declares that the decorated type shall not be creatable from QML. This takes
effect if the type is available in QML, by a preceding ``QmlElement``
decorator. The reason will be emitted as error message if an attempt to create
the type from QML is detected.
Some QML types are implicitly uncreatable, in particular types exposed with
``QmlAnonymous``.
Passing None or no argument will cause a standard message to be used instead.

QML_IMPORT_MINOR_VERSION = 0 # Optional

.. note:: The order of the decorators matters, ``QmlUncreatable`` needs to be preceded by ``QmlElement``.
