tkinter如何做一个无误的,带滚动条的text

要求

1. Text 带两个 Scollbar
2. XScrollbar必须保持本次最大长度显示

from tkinter import *

r=Tk()
r.title('try')

scrollbary=Scrollbar(r,orient=VERTICAL) #滚轮初始
scrollbarx=Scrollbar(r,orient=HORIZONTAL)

text=Text(r,wrap=NONE)

scrollbary.pack(side=RIGHT,fill=Y)
scrollbarx.pack(side=BOTTOM,fill=X)

text.pack(side=LEFT,padx=10,pady=10) #文本初始

scrollbary.config(command=text.yview)
scrollbarx.config(command=text.xview)

text.config(yscrollcommand=scrollbary.set)
text.config(xscrollcommand=scrollbarx.set)

text.insert(END,'''tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter tkinter
