出现此问题的原因是，您正在基于窗口几何体设置绝对位置，该几何体还可以包括标题栏；在您的情况下，垂直位置将始终是window.y() + titlebar.height() + y，因此如果窗口最大化，标题栏将没有高度，从而显示所需的“正确”位置。你知道吗

qmdusubwindows的正确实现是使用^{}添加其内容。这几乎就像对QMainWindow使用setCentralWidget()。你知道吗

class SubForm(QMdiSubWindow):
    def __init__(self):
        super().__init__()

        # create the widget and set its ui
        self.subform = QWidget()
        subform_ui = Ui_DataForm()
        subform_ui.setupUi(self.subform)

        # set the widget for the window
        self.setWidget(self.subform)

        # you should *not* do this!!!
        self.tb = Ui_FormToolBar("data_print","n")
        self.tb.setupUi(self)

关于最后几行，您应该永远不要在同一个小部件上多次调用setupUi，甚至不要针对一个类与它所期望的不同的对象：在您的例子中，Ui\u FormToolBar应该是一个QWidget，但是您使用的是qmdusubwindow；虽然它似乎可以工作，你将来可能会面临一些严重的问题。您应该做的是创建一个单独的QWidget并使用表单setupUi。你知道吗

最后，我强烈建议您不要编辑由pyuic生成的python文件来创建程序；请阅读有关如何正确use the files created with Designer的官方文档。你知道吗
