QFont.Decorative: 'fantasy',
^^^^^^^^^^^^^^^^
AttributeError: type object 'QFont' has no attribute 'Decorative'
With PyQt6 this is now QFont.StyleHint.Decorative. I don't know how pyface is supposed to handle this difference.

Thanks for the report - due to issues like this PyQt6 is not yet supported.
I think a simple PR to change it to
QFont.StyleHint.Decorativewould be backward compatible. But it is likely there would be multiple other similar changes. This update process is very hard to automate.opoplawski commentedon Jun 12, 2023
I tried changing it to
QFont.StyleHint.Decorativebut that seemed to break the Qt5 tests.johannesloibl commentedon Feb 13, 2024
