python tkinter滚动条和文本小部件问题

Question

我正在尝试获取两个都有滚动条的文本框。但是，当我尝试此操作时：

from Tkinter import *

root = Tk()

s_start = Scrollbar(root)
t_start = Text(root, width=50, height=10)

t_start.focus_set()

s_start.pack(side=RIGHT, fill=Y)
t_start.pack(side=LEFT, fill=Y)

s_start.config(command=t_start.yview)
t_start.config(yscrollcommand=s_start.set)

s_end = Scrollbar(root)
t_end = Text(root, width=50, height=10)

t_end.focus_set()

s_end.pack(side=RIGHT, fill=Y)
t_end.pack(side=LEFT, fill=Y)

s_end.config(command=t_end.yview)
t_end.config(yscrollcommand=s_end.set)

root.mainloop()

会发生这种情况：

如果不清楚，这些是两个单独的文本框，右侧文本框在功能上绑定到内部滚动条，左侧文本框在功能上绑定到外部滚动条。

诀窍是使用框架并将滚动条添加到框架而不是根。

from Tkinter import *

root = Tk()

left = Frame(root)
right = Frame(root)

t_start = Text(left, width=20)
t_start.pack(side=LEFT, fill=Y)
s_start = Scrollbar(left)
s_start.pack(side=RIGHT, fill=Y)
s_start.config(command=t_start.yview)
t_start.config(yscrollcommand=s_start.set)

t_end = Text(right, width=20)
t_end.pack(side=LEFT, fill=Y)
s_end = Scrollbar(right)
s_end.pack(side=RIGHT, fill=Y)
s_end.config(command=t_end.yview)
t_end.config(yscrollcommand=s_end.set)

left.pack(side=LEFT, fill=Y)
right.pack(side=RIGHT, fill=Y)

root.geometry("500x200")
root.mainloop()
