显示列表数据（QListView控件）

'''

from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QListView, QMessageBox
from PyQt5.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()
        listModel = QStringListModel()
        self.list = ["列表项1","列表项2", "列表项3"]

        listModel.setStringList(self.list)

        listview.setModel(listModel)
        listview.clicked.connect(self.clicked)
        layout.addWidget(listview)

        self.setLayout(layout)

    def clicked(self,item):
        QMessageBox.information(self,"QListView","您选择了：" + self.list[item.row()])



if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = ListViewDemo()
    win.show()
    sys.exit(app.exec_())

遇到的问题

搞不明白item里有哪些方法：
于是打印出来看看

['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'child', 'column', 'data', 'flags', 'internalId', 'internalPointer', 'isValid', 'model', 'parent', 'row', 'sibling', 'siblingAtColumn', 'siblingAtRow']

改写效果展示

改写注意点

只有widget才能手动添加item
