Python Tkinter如何使文本框滚动

Question

我编写了以下代码来快速抓取并显示来自维基百科的信息。除非Wiki摘要包含的信息多于框可以显示的信息，否则它的效果很好。我认为添加sticky = N + S + E + W会解决这个问题，但它似乎没有做任何事情。如果有太多信息要一次显示在文本框中，如何更新此代码以使其滚动？

在此处输入代码

import sys
from tkinter import *
import wikipedia

def search_wiki():
    txt = text.get()           # Get what the user entered into the box
    txt = wikipedia.page(txt)  # Search Wikipedia for results
    txt = txt.summary          # Store the returned information
    lblText = Label(main, text=txt,justify=LEFT,wraplength=600, fg='black',
                    bg='white', font='times 12 bold').grid(row = 50,
                    column = 1, sticky=N+S+E+W)

main = Tk()
main.title("Search Wikipedia")
main.geometry('750x750')
main.configure(background='ivory3')
text = StringVar()

lblSearch = Label(main, text = 'Search String:').grid(row = 0, column = 0,
                                                      padx = 0, pady = 10)
entSearch = Entry(main, textvariable = text, width = 50).grid(row = 0,
                                                              column = 1)

btn = Button(main, text = 'Search', bg='ivory2', width = 10,
             command = search_wiki).grid(row = 0, column = 10)


main.mainloop()

用更合适的小部件替换标签，例如

lblText = ScrolledText(main,
                      bg='white',
                      relief=GROOVE,
                      height=600,
                      #width=400,
                      font='TkFixedFont',).grid(row = 50,
                      column = 1, sticky=N+S+E+W)

如果要显示可滚动的文本，则应使用Text小部件。你不能滚动Label，滚动一组Labels相对困难。 Text小部件是目前可滚动文本的最佳选择。

感谢你的帮助。我终于想出了一切。这是我的新代码，以防任何其他人遇到此类或类似的东西。

import sys
from tkinter import *
from tkinter import scrolledtext
from wikipedia import *

def search_wiki():
    txt = text.get()           # Get what the user eneterd into the box
    txt = wikipedia.page(txt)  # Search Wikipedia for results
    txt = txt.summary          # Store the returned information
    global texw
    textw = scrolledtext.ScrolledText(main,width=70,height=30)
    textw.grid(column=1, row=2,sticky=N+S+E+W)
    textw.config(background="light grey", foreground="black",
                 font='times 12 bold', wrap='word')
    textw.insert(END, txt)

main = Tk()
main.title("Search Wikipedia")
main.geometry('750x750')
main.configure(background='ivory3')

text = StringVar()

lblSearch = Label(main, text = 'Search String:').grid(row = 0, column = 0)
entSearch = Entry(main, textvariable = text, width = 50).grid(row = 0,
                                                          column = 1)

btn = Button(main, text = 'Search', bg='ivory2', width = 10,
             command = search_wiki).grid(row = 0, column = 10)

main.mainloop()
