        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)
