如何等待messagebox的返回值

import tkinter.messagebox as messagebox
from tkinter import Tk

def on_messagebox_close(result):
    # 处理返回值
    print("返回值:", result)

root = Tk()
root.withdraw()  # 隐藏主窗口

# 调用messagebox并指定回调函数
messagebox.showinfo("标题", "内容", icon=messagebox.INFO, command=lambda: on_messagebox_close("OK"))

root.mainloop()

import javax.swing.JOptionPane;

public class MessageBoxExample {
    public static void main(String[] args) {
        // 调用messagebox并等待返回值
        int result = JOptionPane.showConfirmDialog(null, "内容", "标题", JOptionPane.YES_NO_OPTION);

        // 处理返回值
        if (result == JOptionPane.YES_OPTION) {
            System.out.println("用户点击了Yes");
        } else if (result == JOptionPane.NO_OPTION) {
            System.out.println("用户点击了No");
        } else {
            System.out.println("用户关闭了messagebox");
        }
    }
}
