Use tkinter.ttk是一个用于设置tkinter小部件样式的模块
我正在用python做一个文本编辑器，但是我怎么能改变滚动条的颜色呢？

• 添加import ttk命名空间。
• 添加style = ttk.Style()
• 添加style.theme_use('classic'
• 添加style.configure用于垂直和水平。

小片段：

from tkinter import *
from tkinter import filedialog
from tkinter import ttk

# creating our root
root = Tk()
root.title("Text Editor")
root.geometry("1200x640")
root.config(bg="black")

style = ttk.Style()
style.theme_use('classic')
style.configure('Horizontal.TScrollbar',
                background='green',
                bordercolr='red',
                arrowcolor='white'
                )

style.configure('Vertical.TScrollbar',
                background='green',
                bordercolr='red',
                arrowcolor='white'
                )
 
# creating our frame
my_frame = Frame(root)
my_frame.pack(pady=5) 

# creating our vertical scroll bar
text_scroll = ttk.Scrollbar(my_frame, orient="vertical")
text_scroll.pack(side=RIGHT, fill=Y)

# creating our horizantal scroll bar
h_scroll = ttk.Scrollbar(my_frame, orient="horizontal")
h_scroll.pack(side=BOTTOM, fill=X)

# creating our text box
my_text = Text(my_frame, width=97,
               height=25, font=("Helvetica", 16),
               #selectbackground="aqua",         
               #selectforeground="blue",
               undo=True,
               xscrollcommand=h_scroll.set,
               yscrollcommand=text_scroll.set,
               wrap="none",                             
               bg="#333", fg="aqua")
my_text.pack()

# configure our scroll bar
text_scroll.config(command=my_text.yview)
h_scroll.config(command=my_text.xview)
 

# main loop
root.mainloop()
