Question

我正在为一个名为组织者的项目制作应用程序。这是一个组织应用程序。我有一个问题，当你勾选一个复选框时，他们都会检查。

我该如何解决这个问题？

跑完之后去：清单 - ＆gt;输入A值 - ＆gt;点击“添加分配” - ＆gt;重复几次 - ＆gt;尝试点击一个

另外，我的.update（）有效，但似乎仍然会导致错误？你知道为什么吗？

谢谢！

        SubBtn.place(x=25,y=200)

        BackBtn = tk.Button(self, text='Back', command=lambda: controller.show_frame(StartPage))
        BackBtn.place(x=250,y=400)

您对两个复选框使用相同的变量。将变量创建移动到循环内部，以使用不同的变量。

var_list = []
for z in AsgnList:
    var = tk.IntVar()
    tk.Checkbutton(self, text=z, variable=var).place(x=200,y=yVal)
    yVal += 25         
    var_list.append(var)

也就是说，您可能希望存储变量，以便检查以后标记的复选框。所以我添加了一个var_list列表对象来存储所有创建的var。

两个复选框单击时检查
