如何从 pyqt5 中的 QListView 获取项目值？

Question

连接到我的数据库后，我尝试从 QListView 获取所有项目值但它没有 text() 方法或任何其他我尝试使用 model.data() 但它 returns 出现以下错误：

File "c:\Users\inter\Desktop\neosun\main copy 9.py", line 88, in addToPlaylist item = model.data(index, 1, Qt.DisplayRole) TypeError: data(self, QModelIndex, role: int = Qt.DisplayRole): argument 1 has unexpected type 'int'

class MainWindow(QMainWindow):
    def __init__(self, *args, **kwargs):
        super(MainWindow, self).__init__(*args, **kwargs)
        self.setGeometry(900,180,800,600)
        self.setWindowTitle("Media Display")
        self.setWindowIcon(QIcon('favicon.png'))
        self.model = QSqlQueryModel()
        self.model.setQuery("SELECT path FROM files")
        
        self.listview = QListView()
        self.listview.setModel(self.model)
        self.listview.setModelColumn(1)    
        self.getData()

    
    def getData(self):
        model = self.listview.model()
        for index in range(model.rowCount()):
            # item = model.data(index)
            item = model.data(index, 1, Qt.DisplayRole)
            print(item)

Qt 使用 QModelIndex class to locate data within any model, so you cannot just use integers to access them, but model.index(row, column, parent=None) 必须改用（可选的 parent 参数用于多维模型，如树模型）。

    def getData(self):
        model = self.listview.model()
        for <b>row</b> in range(model.rowCount()):
            <b>index = model.index(row, 1)</b>
            item = model.data(<b>index</b>, Qt.DisplayRole)
            print(item)
