	print("点击的是：" + str(qModelIndex.row()))

1.4 QListView Sample

from PySide2.QtWidgets import QApplication, QWidget, QVBoxLayout, QListView, QMessageBox
from PySide2.QtCore import QStringListModel

import sys


class ListViewDemo(QWidget):
    def __init__(self, parent=None):
        super(ListViewDemo, self).__init__(parent)
        self.setWindowTitle("QListView 例子")
        self.resize(300, 270)

        layout = QVBoxLayout()
        listView = QListView()  # 创建一个listview对象

        slm = QStringListModel()  # 创建mode
        self.qList = ['Item 1', 'Item 2', 'Item 3', 'Item 4']  # 添加的数组数据
        slm.setStringList(self.qList)  # 将数据设置到model
        listView.setModel(slm)  # 绑定 listView 和 model

        listView.clicked.connect(self.clicked_list)  # listview 的点击事件
        layout.addWidget(listView)  # 将list view添加到layout
        self.setLayout(layout)  # 将lay 添加到窗口

    def clicked_list(self, qModelIndex):
        QMessageBox.information(self, "QListView", "你选择了: " + self.qList[qModelIndex.row()])
        print("点击的是：" + str(qModelIndex.row()))


if __name__ == "__main__":
    app = QApplication(sys.argv)

    win = ListViewDemo()
    win.show()

    sys.exit(app.exec_())

2. QTableWidget

Official Document: https://doc.qt.io/qt-5.15/QTableWidget.html

2.1 QTableWidget shields double clicks on a item

1 2	`item = table_widget.item(index, column) item.setFlags(QtCore.Qt.ItemIsEnabled)`

# Insert Row
new_row_index = table_widget.rowCount()
table_widget.insertRow(new_row_index)
# Update Row Data
table_widget.setItem(new_row_index, 0, QTableWidgetItem('Data0'))
table_widget.setItem(new_row_index, 1, QTableWidgetItem('Data1'))
table_widget.setItem(new_row_index, 2, QTableWidgetItem('Data2'))
