如何将滚动条添加到Tkinter文本框小部件

Question

我最近重新访问了一个较旧的GUI项目，并决定其文本小部件需要一个垂直滚动条，因为输出通常很长。我一直无法找到这个，并且想知道我是否能得到一些帮助。这是必要的代码：

from Tkinter import *

class Application(Frame):
    def __init__(self,master):
        Frame.__init__(self,master)
        self.grid()
        self.widget()
    def widget(self):
        self.results_plain_label = Label(self,
                                         text = "Deciphered Message")
        self.results_plain_label.grid(row = 13, column =5, pady = 5 )
        self.results_plain_text = Text (self, width = 100, height = 6,
        wrap = WORD, font ("Times New Roman", ))
        self.results_plain_text.grid(row = 14, column = 5, pady = 5, sticky = W)

Mainloop initialization stuff

那么，我如何在scroll-bar文本框中添加results_plain_text？
