Question

我有这段代码：

class ManifestModel(QtSql.QSqlTableModel):
    def __init__(self, parent=None, db=QtSql.QSqlDatabase()):
        super(ManifestModel, self).__init__(parent, db)

    def flags(self, index):
        if (index.column() == 4):
            return QtCore.Qt.ItemIsEnabled
        elif (index.column() == 6):
            return QtCore.Qt.ItemIsEnabled
        elif (index.column() == 3):
            return QtCore.Qt.AlignHCenter       
        else:
            return QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | QtCore.Qt.ItemIsEditable

当我运行它时出现错误：

builtins.TypeError: invalid result from ManifestModel.flags(), AlignmentFlag cannot be converted to PyQt5.QtCore.ItemFlags in this context

在使用ManifestModel的同一例程中，我有代码：

ui.label = QtWidgets.QLabel(ui.page)
ui.label.setGeometry(QtCore.QRect(308, 0, 131, 20))
ui.label.setAlignment(QtCore.Qt.AlignCenter)

那么我需要做些什么才能更改QTableView列中的对齐方式？

对象在模型的data()方法中处理。所以尝试类似的事情：

class ManifestModel(QtSql.QSqlTableModel):

    def data(self, index, role=QtCore.Qt.DisplayRole):
        if role == QtCore.Qt.TextAlignmentRole and index.column() == 3:
             return QtCore.Qt.AlignHCenter
        return super(ManifestModel, self).data(index, role)
