Tkinter:滚动条的使用工具是什么？（当前使用带有标签的列表框）

Question

我现在有一个带有滚动条的列表框，但是在列表框中我有一系列的标签。我想能够向下滚动列表框时，标签的数量超过预先确定的列表框大小限制。你知道吗

我刚刚发现我的方法是不可能的，但我想知道是否有另一个小部件，我可以用来绕过我的问题？如果没有，是否有其他方法构建列表框的内容，以便滚动条可以正常运行？你知道吗

我的代码示例如下：

from tkinter import *

您可以将小部件插入文本小部件或画布。它们都有插入其他小部件的方法。不能对要滚动的项目使用pack、place或grid，必须使用这些小部件特有的特殊方法。你知道吗

最常见的选择是创建一个画布，向画布中添加一个框架，然后可以使用pack、place或grid将其他小部件放在框架中。对你所做的事情来说，这可能是过分的。如果您只需要一个相同标签的垂直堆栈，那么文本小部件可能是最简单的。你知道吗
