PyQt6 migration: scoped enum errors on startup

[zarcoder]

Description

When migrating Friture from PyQt5 to PyQt6, several AttributeError exceptions occur on startup due to PyQt6's scoped enums. In PyQt6, all Qt enums must be accessed through their full scope (e.g. QIcon.Mode.Normal instead of QIcon.Normal).

Environment

• Platform: macOS (Darwin)
• Python: 3.14.3
• PyQt6: 6.11.0

Errors encountered

1. qmlRegisterSingletonType argument order changed

TypeError: arguments did not match any overloaded call:
  qmlRegisterSingletonType(a0: type, uri: str, major: int, minor: int,
    factory: Callable[[QQmlEngine, QJSEngine], Any], name: str = None):
    argument 5 has unexpected type 'str'

Fix: swap name and factory arguments.

2. Qt.RichText → Qt.TextFormat.RichText

AttributeError: type object 'Qt' has no attribute 'RichText'

3. QIcon.Normal / QIcon.Off

AttributeError: type object 'QIcon' has no attribute 'Normal'

Fix: QIcon.Mode.Normal, QIcon.State.Off

4. QPalette.Window / QPalette.Base

AttributeError: type object 'QPalette' has no attribute 'Window'

Fix: QPalette.ColorRole.Window, QPalette.ColorRole.Base

5. QSizePolicy.Minimum / QSizePolicy.Expanding

Fix: QSizePolicy.Policy.Minimum, QSizePolicy.Policy.Expanding

6. QDialogButtonBox.setOrientation() removed in Qt6

Fix: Remove the call (orientation is automatic).

7. QSGGeometry.DrawTriangles → QSGGeometry.DrawingMode.DrawTriangles

8. QSGNode.OwnsGeometry → QSGNode.Flag.OwnsGeometry

9. QSGNode.DirtyGeometry → QSGNode.DirtyStateBit.DirtyGeometry

10. QQuickItem.ItemHasContents → QQuickItem.Flag.ItemHasContents

11. QML imports: version numbers must be removed

All import QtQuick 2.15 style imports must become import QtQuick.
