python - Tkinter 忘记在另一个函数中创建的小部件

Question

我想知道如何忘记一个小部件而不是另一个功能？我的代码非常困惑。

def page2(cur1):
    label2 = Label(root, text="How much would you like to convert?")
    entry1 = Entry(root)
    buttonSubmit = Button(root, text="Submit", command=lambda: get_entry(entry1, cur1))

    label2.grid(row=1, columnspan=5)
    entry1.grid(row=2, sticky="w")
    buttonSubmit.grid(row=2, column=1)

我希望能够从另一个函数中忘记这些小部件，如下所示:

def forget():
    label2.grid_forget()
    entry1.grid_forget()

提前致谢。

如果您发现自己非常需要这个，您应该 re-structure your program using classes .

您可以将小部件的创建移至全局范围，并在需要时网格/忽略它们。

#create your widgets in global scope so you can reach them in any function
label2 = Label(root, text="How much would you like to convert?")
entry1 = Entry(root)

def page2(cur1):
    buttonSubmit = Button(root, text="Submit", command=lambda: get_entry(entry1, cur1))

    label2.grid(row=1, columnspan=5)
    entry1.grid(row=2, sticky="w")
    buttonSubmit.grid(row=2, column=1)

def forget():
    label2.grid_forget()
    entry1.grid_forget()
