我怎样才能使我的文件具有可点击功能

Question

这是我的示例代码，因为我想在 Qscrollbar 小部件中查看我所有文件的特定目录，直到它工作正常。但在那之后，当我 select 任何一个文件时，我想在同一滚动区域显示该文件数据，但我不知道我该怎么做我的文件是可点击的所以请告诉我该怎么做我的所有文件都是可点击的，提前谢谢你这是我的代码：

class Example(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super( Example, self).__init__(parent)

        self.lay1.addWidget(self.btn)
        self.btn.clicked.connect(self.open_file)
        self.scrollArea =QtGui. QScrollArea()
        self.scrollArea.setBackgroundRole(QtGui.QPalette.Light)

        self.scrollArea.setWidgetResizable(True)
        self.mainLayout = QtGui.QGridLayout()

        self.mainLayout.addLayout(self.lay1,0,0)
        self.mainLayout.addWidget(self.scrollArea,0,1)

        self.setCentralWidget(QtGui.QWidget(self))
        self.centralWidget().setLayout(self.mainLayout)
        self.setGeometry(100,100,800,500)

    def open_file(self):
        self.w = QtGui.QWidget()
        self.lay =QtGui. QVBoxLayout()

        self.model = QtGui.QStandardItemModel(self)
        self.tableView =QtGui. QTableView(self)
        self.tableView.setModel(self.model)
        self.tableView.horizontalHeader().setStretchLastSection(True)

        self.appendRowItems("/home/cioc/Documents/GPR/GRP")

        self.lay.addWidget(self.tableView)
        self.w.setLayout(self.lay)
        self.scrollArea.setWidget(self.w)


    def appendRowItems(self, dir):
        for root, dirs, files in os.walk(dir):
            if root == dir:
                for file in files:
                    self.model.appendRow(QtGui.QStandardItem(file))
                    # self.model.isSelectable(True).connect(onFileClicked)


    def onFileClicked(self, file):
        self.w = QtGui.QWidget()
        self.lay = QtGui.QVBoxLayout()
        self.model = QtGui.QStandardItemModel(self)
        self.tableView = QtGui.QTableView(self)
        self.tableView.setModel(self.model)
        self.tableView.horizontalHeader().setStretchLastSection(True)

        with open(file.fileName(), "rb") as fileInput:
            for row in csv.reader(fileInput):
                items = [
                    QtGui.QStandardItem(field)
                    for field in row
                ]
                self.model.appendRow(items)

        self.lay.addWidget(self.tableView)
        self.w.setLayout(self.lay)
        self.scrollArea.setWidget(self.w)
