Tkinter 关闭行为

Tkinter 窗口的关闭行为可以通过 protocol 方法设置

代码实现示例

import tkinter as tk
import tkinter.messagebox as messagebox
import ctypes  # 导入模块

root = tk.Tk()
ctypes.windll.shcore.SetProcessDpiAwareness(1)
ScaleFactor = ctypes.windll.shcore.GetScaleFactorForDevice(0)
root.tk.call("tk", "scaling", ScaleFactor / 75)
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()

window_width = 650
window_height = 190

x = int((screen_width - window_width) / 2)
y = int((screen_height - window_height) / 2)

root.geometry(f"{window_width}x{window_height}+{x}+{y}")
root.resizable(False, False)

def on_closing():  # 关闭窗口时触发
    if messagebox.askokcancel("退出程序", "你确定要退出吗？"):
        root.destroy()

root.protocol("WM_DELETE_WINDOW", on_closing)  # 关闭窗口时触发
root.mainloop()
