Question

我已经在网站上阅读了一些线程来尝试解决此问题，但是没有发现我没有尝试过仍然无法解决的问题。

我很难让滚动条显示给我的小部件。我有2个滚动条，它们在另一个窗口中以相同的方式为列表框和文本小部件编写，并且显示并正常运行，但是在此窗口中，将不会显示2个滚动条。我的代码与另一个窗口中其他起作用的滚动条的代码相同，但是由于某些原因，这两个未显示。

将它们放置在单个位置上一些建议将不胜感激。

代码：

import tkinter
from tkinter import *
window_3 = tkinter.Toplevel()
window_3.title('Recipes')
window_3.wm_iconbitmap('recipe.ico')
w = 1024
h = 612
ws = window_3.winfo_screenwidth()
hs = window_3.winfo_screenheight()
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
window_3.geometry('%dx%d+%d+%d' % (w, h, x, y))
window_3.title('Recipes')

window_3.mainloop()

Answer 1

您忘了告诉Scrollbar()它的母版，因此它自然会假定它是根窗口。做：

yscroll = Scrollbar(window_3, ... etc.

顺便说一下，ingred和instruct都与同一个滚动条关联：yscroll，但我只是从剪切和粘贴代码中收集它。另外，您定义StringVar()实例的名称与文本小部件的名称相同。

滚动条未显示-Tkinter
