Python 两个.py数据导入它们，但它给出了一个错误名称xx未定义

我有个大问题

所以我有一个主窗口和第二个窗口。如果我点击按钮：

buttonsite

它将打开我的第二个窗口，直到现在没有问题。我在第二个窗口上有一个按钮按钮

调用：Ilias_按钮

它将关闭第二个按钮（使用命令

WindowButton.close（）

），但如果我在第二个窗口上单击

Ilias_按钮

，它会给我一个调用的错误

名称错误：未定义名称“WindowButton”

即使我将第二个窗口导入到主窗口文件中 请帮我一下。。我怎样才能解决这个问题

这是我的主窗口

在第二个文件的setupUi中，存储一个ref to WindowButton供以后使用：

class Ui_WindowButton(object):
    def setupUi(self, WindowButton):
        self.myMasterWindowButton = WindowButton
    ...
    def IliasBrowser(self):
        self.myMasterWindowButton.close()

---

这是一个可变范围的问题：windowButton是setupUi的本地设置，在iliasBrowser中不存在。您可能希望在self中保存e引用。您还应该遵守pep8或qt的命名约定，否则您很快就会在类名和变量名或函数名之间迷失方向。您能告诉我如何保存e引用吗？@Demi Lune您能简要解释一下如何在self中保存e引用吗？所以我能解决这个问题？天哪，@Demi Lune非常感谢你。从12个小时以来，我一直在努力解决这个问题。非常感谢你的支持。我还有一个问题，是使用init函数更好，还是编写代码更好？Qt使用setupUi（显然）设置Ui。您可以使用

\uuuu init\uuuu

设置任何与UI无关的变量（尽管我还没有在您的代码中发现任何变量）。
