我有一个顶层窗口小部件，它询问用户他想产生什么窗口小部件，然后询问cnf。什么和东西都不重要。
cnf将在Scrollframe-Table-something中被问到（我真的不知道如何描述它^^'）。对于该Scrollframe及其滚动条，我制作了一个Frame，因此可以轻松地左右包装它。但是，以某种方式，Scrollframe会将Tk窗口（顶层的根目录）作为主窗口。
这是代码-我找不到我的错误：

在有人问Scrollframe中的self.scrollable是干什么的之前：我将在稍后实现的MouseWheel绑定。
答案 0 :(得分：4)
在这一行中，您没有将主服务器传递给超类'__init__：
Frame.__init__(self,height=height,width=width)
只需将其更改为：
Frame.__init__(self,master=master, height=height,width=width)
也就是说，Python的一般建议是使用super()而不是对超类名称进行硬编码：
super().__init__(master=master, height=height, width=width)
