    Description

      Inside QtCore.QAbstractItemModel.data() we might have code like this

              if role == QtCore.Qt.TextAlignmentRole:
            if case_a:
                return QtCore.Qt.AlignRight
            elif case_b:
                return QtCore.Qt.AlignRight | QtCore.Qt.AlignVCenter
            else:
                return QtCore.Qt.AlignVCenter

      Case a works (kind of) in that we get right alignment but vertical alignment changes from the AlignVCenter default to AlignTop.

      Case b does not work: the alignment value is ignored.

      Case c works.

      What seems to be going on is that the caller of data() expects an int return not an Alignment object. If we replace by

              if role == QtCore.Qt.TextAlignmentRole:
            if case_a:
                return int(QtCore.Qt.AlignRight)
            elif case_b:
                return int(QtCore.Qt.AlignRight | QtCore.Qt.AlignVCenter)
            else:
                return int(QtCore.Qt.AlignVCenter)

      it works.

      Simple example enclosed.
