from PyQt5.QtGui import QIcon, QPixmap, QStandardItem, QStandardItemModel

        super(WindowClass, self).__init__(parent)
        self.layout = QVBoxLayout()
        self.resize(200, 300)
        listModel = QStringListModel()
        listView = QListView()
        items = ["张三", "李四", "小明", "JONES"]

        listModel.setStringList(items)
        listView.setModel(listModel)

        listView.clicked.connect(self.checkItem)

        self.layout.addWidget(listView)
        widget = QWidget()
        widget.setLayout(self.layout)
        self.setCentralWidget(widget)

    def checkItem(self, index):
         QMessageBox.information(self, "ListView", "选择项是：%d"%(index.row()))


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

# QListView使用
from PyQt5.QtWidgets import QMessageBox,QListView, QStatusBar, QMenuBar,QMenu,QAction,QLineEdit,QStyle,QFormLayout, QVBoxLayout,QWidget,QApplication ,QHBoxLayout, QPushButton,QMainWindow,QGridLayout,QLabel
from PyQt5.QtGui import QIcon,QPixmap,QStandardItem,QStandardItemModel

        self.layout = QVBoxLayout()
        self.resize(200, 300)
        listView = QListView()
        listView.setViewMode(QListView.ListMode)#或者使用QListView.IconMode  QListView.ListMode
        # listView.setMovement(QListView.Static)
        listView.setIconSize(QSize(20,20)) # 图标的大小（原始图标大小如果100,100，此时设置草果原始大小则失效）
        listView.setGridSize(QSize(60,40))#每个选项所在网格大小（每个选项外层grid宽高）
        listView.setMaximumHeight(200)#listView整体最大高度
        # listView.setMinimumSize(QSize(200,200))#listView最小面积（一般如果设置最大高和宽属性后就不设置这个属性了）
        # listView.setMaximumSize(QSize(500,500))#listVIew最大面积（一般如果设置最大高和宽属性后就不设置这个属性了）
        listView.setMinimumHeight(120)#listView最小高度

        listView.setResizeMode(QListView.Adjust)
        #listView.setMovement(QListView.Static)#设置图标可不可以移动，默认是可移动的，但可以改成静态的：

        self.item_1 = QStandardItem(QIcon("./image/save.ico"), "普通员工A");
