componentComplete

componentComplete()

Must be from QML in the signal Component. At this point all static values and binding values have been assigned to the class.

This is an awful fix required because QQmlParserStatus does not work Meant to use https://doc.qt.io/qtforpython-6/PySide6/QtQml/QQmlParserStatus.html instead :return:
