Description

Returning a PySide 6 enum for role Qt.ItemDataRole.TextAlignmentRole from the data() method of a model is broken in Qt 6.3.1. Sample code below:

from PySide6.QtCore import Qt, QAbstractTableModel
from PySide6.QtWidgets import QTableView, QApplication
class M(QAbstractTableModel):    
    def rowCount(self, *a):
        return 1
    def columnCount(self, *a):
        return 1
    def data(self, index, role):
        if role == Qt.ItemDataRole.DisplayRole:
            return 'testing'
        if role == Qt.ItemDataRole.TextAlignmentRole:
            ans = Qt.AlignmentFlag.AlignVCenter | Qt.AlignmentFlag.AlignHCenter
            return ans
app = QApplication([])
v = QTableView()
v.setModel(M())
v.resize(v.sizeHint())
v.show()
app.exec()

The string testing is displayed in the top left corner instead of centered. Changing return ans to return int(ans) gives the expected behavior. Therefore, conversion of the PySide6 enum to int is failing. This used to work fine with Qt 6.2.3. It also fails with PyQt6.
