如何使用tkinter检查widget是否为其他widget的后代

import tkinter as tk

root = tk.Tk()
button = tk.Button(root, text="按钮")
label = tk.Label(root, text="标签")
button.pack()
label.pack()

is_button_mapped = button.winfo_ismapped()
is_label_mapped = label.winfo_ismapped()
print("按钮是否已映射到屏幕上：", is_button_mapped)
print("标签是否已映射到屏幕上：", is_label_mapped)

按钮是否已映射到屏幕上： True
标签是否已映射到屏幕上： True

def is_descendant(parent, widget):
    children = parent.winfo_children()
    if widget in children:
        return True
    for child in children:
        if is_descendant(child, widget):
            return True
    return False

is_button_descendant = is_descendant(root, button)
is_label_descendant = is_descendant(root, label)
print("按钮是否为root的后代：", is_button_descendant)
print("标签是否为root的后代：", is_label_descendant)
