【问题描述】：

我正在尝试制作一个简单的输入表单，它接受某些输入并在表格中显示输出。 根据代码，我得到以下输出。

但我正在寻找以下输出。

以下是我尝试过的代码sn-p。

                rowCount=0

                for item in vehicleFileList :
                        print(item)
                        self.setItem(rowCount,0,QTableWidgetItem(item))
                        rowCount+=1


def main():
        app = QApplication(sys.argv)
        window = MainWindow()
        sys.exit(app.exec_())

if __name__ == '__main__':
    main()

我需要进行哪些更改才能获得我选择的窗口定位？

【参考方案1】：

注意：第二个窗口不是第一个窗口的子窗口。

这个想法是计算第一个窗口的几何形状并使用该信息来修改第二个窗口的几何形状：

table = MyTable(vehicleFileList, numOfFiles, 2, self)
# add Qt.Window to table's flags
table.setWindowFlags(table.windowFlags() | Qt.Window)
table.resize(self.width(), table.sizeHint().height())
table.window().move(self.geometry().bottomLeft())
table.show()
