如何把QTableWidgetchildwindow放在parentwindow前面或者parentwindow下面？

Question

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 table 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片段。

                    # add Qt.Window to table's flags

        def __init__(self, vehicleFileList, *args):
                QTableWidget.__init__(self, *args)
                self.data = vehicleFileList

                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 window 定位？

Answer 1

注：第二个window不是第一个window的子代。

想法是计算第一个 window 的几何形状并使用该信息修改第二个 window 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()
