Python 3.x 如何从不同的帧访问复选框值？

python-3.x tkinter

Python 3.x 如何从不同的帧访问复选框值？,python-3.x,tkinter,Python 3.x,Tkinter,我正在创建一个tkinter应用程序，尝试从不同帧的多个复选框中获取值。当我在一个帧中单击复选框时，它也会在另一个帧中被选中。我想知道如何从不同的帧访问复选框值当尝试选中复选框（框架1中的Tb1）时，它也在签入（NLframe中的NLTb1）。我想知道如何分别访问这两个复选框值 from tkinter import * def create_widgets_in_first_frame(): task_type=Button(main_frame,text='Task Type',c

首先在您的

退出程序

函数中，您调用要销毁的

根窗口

。你以前从未定义过这个。我猜你是指root.destroy（）

<强>第二版/强>，我想你可能想考虑使用单选按钮代替复选框。单选按钮只允许选中一个选项。这将阻止您在同一页上同时选中“通过”和“失败”框

就问题而言，您的复选框之所以在另一个框架中保持选中状态，是因为您只是忘记了网格，而没有破坏小部件。网格只是组织小部件的东西，而不是实际的小部件本身。因此，当您忘记网格并移动到新框架时，该网格点中的小部件将保持其状态。然而，这并不是说销毁小部件就是解决方案。要解决问题，只需确保将按钮的状态存储在变量中。我对你的代码做了一些调整，并使其正常工作
