Python 如何为提出的QWidget设置QVariantAnimation？

我有这个代码在菜单之间切换

一切都很好，直到我把它关掉（自我） 为什么代码如此不稳定

问题

我需要

我尝试使用clear（）或if来处理self.menu\u group\u ani 但无论我做什么，代码都不能正常工作 单击。连接也未给出所需的结果

如何修复？

1）在代码生成错误时验证代码。2） 消除不必要的导入，例如从PyQt5.QtQml导入QQmlApplicationEngine的

，因为它们会分散注意力。3） 不仅要放置图像，还要解释错误所在。4） 这段代码的具体目的是什么？@eyllanesc错误是在函数off（）期间，radio没有切换到self.radio_1，这就是为什么当我从self.mv_rad_arr[0]切换到self.mv_rad_arr[1]时会发生错误。必须在运行前清除self.menu\u group\u ani，或强制关闭（）开关至self.radio\u 1。
