如何在标签中求解覆盖文本 - ＆gt; PYQT标签？

Question

我定义函数，将filepath添加到标签中以进行循环。我使用qfiledialog.getopenfileenames函数加载文件路径中的mdb_paths1变量。然后，在for循环的每个步骤中，我创建一个新标签并将其设置为网格中的另一个位置，然后将文件路径存储在其中。

我有问题。如果我想第二次上传FilePath（第二次克利亚按钮），我的印刷filepaths将得到覆盖。

你能帮助我吗 ？

覆盖标签

Answer 1

尝试以下操作：

        label1_2 = QtWidgets.QLabel(self.centralwidget)
        label1_2.setObjectName("label1")
        label1_2.setText("Uploaded files: ")
        self.grid1.addWidget(label1_2, 1, 1)
        self.labels = []
        self.labels.append(label1_2)
        #---------------------------------------------------------------------------------------------------------

        self.setCentralWidget(self.centralwidget)
        self.retranslateUi(self)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "Data quality controller"))



    def open_mdb1(self):
        mdb_paths1, _ = QFileDialog.getOpenFileNames(
            self.centralwidget,'Select file','./','Access Files (*.mdb *.accdb)'
        )
        total = len(mdb_paths1)
        num_labels = len(self.labels)
        for i in range(total):
            if i < num_labels:
                label = self.labels[i]
                label.setText(mdb_paths1[i])
            else:
                label = QLabel(self.centralwidget)
                label.setText(mdb_paths1[i])
                self.grid1.addWidget(label,self.grid1.rowCount(), 1)
                self.labels.append(label)
