tkinter进度条可以从右向左移动吗？

import tkinter as tk
from tkinter import ttk

def move_progressbar():
    if progressbar['value'] >= 100:
        progressbar['value'] = 0
    progressbar['value'] += 10
    root.after(500, move_progressbar)

root = tk.Tk()
root.title("Progress Bar Demo")

progressbar = ttk.Progressbar(root, orient='horizontal', length=200, mode='determinate', maximum=100)
progressbar.pack(pady=10)

move_progressbar()

root.mainloop()
