如何使用python gui中第一个combobox中选择的值来控制其他combobox的值？

import tkinter as tk
from tkinter import ttk

def on_first_combobox_selected(event):
    selected_value = first_combobox.get()
    
    # 根据第一个ComboBox的选择值更新其他ComboBox的选项
    if selected_value == "选项1":
        second_combobox['values'] = ("选项A", "选项B", "选项C")
    elif selected_value == "选项2":
        second_combobox['values'] = ("选项X", "选项Y", "选项Z")
    else:
        second_combobox['values'] = ()  # 清空其他ComboBox的选项

root = tk.Tk()

# 创建第一个ComboBox
first_combobox = ttk.Combobox(root, values=("选项1", "选项2", "选项3"))
first_combobox.bind("<<ComboboxSelected>>", on_first_combobox_selected)
first_combobox.pack()

# 创建第二个ComboBox
second_combobox = ttk.Combobox(root)
second_combobox.pack()

root.mainloop()
