我正在制作一个自定义消息框小部件。我的工作正在进行中。但就功能而言，我无法让它像 Tkinter 消息框一样真实。这是我的代码。

from tkinter import *
from tkinter.ttk import Style,Frame as fp
class messagebox():
    def __init__(self,parent):
        self.parent = parent
#image in base 64 encoded format to make a round corner window with ttk frame
        borderImageData='''

我想知道如何像普通消息框一样工作？，我的意思是在焦点离开时闪烁，当父窗口有焦点进入/离开时，与父窗口一起出现（意味着不隐藏在后面）。我知道由于过度重定向标志而无法闪烁，但是如果有人给我关于正确的事件绑定以实现闪烁效果的想法，那么我只需在循环中将 2/3 颜色更改为我的工具栏。如果您选择 parent.winfo_children 状态禁用方法，那么它对我不起作用，因为我在绑定事件中有一些标签。任何帮助都会得到帮助。谢谢你！！编辑：我已经删除了用于屏幕居中位置和鼠标拖动的额外行。剩余是必不可少的

所以我在根上做了另一个顶层并使其透明..这种颜色你可以改变你喜欢的方式，并且在停用根后它仍然响应。

import tkinter as tk

root=tk.Tk()
def top():
    top = tk.Toplevel()
    top.overrideredirect(1)

    top2 = tk.Toplevel()
    root.update_idletasks()
    top2.overrideredirect(1)
    top2.config(bg='red')
    top2.attributes('-alpha', 0.11)
    x,y = root.winfo_rootx(), root.winfo_rooty()
    width, height = root.winfo_width(),root.winfo_height()
    top2.geometry("%dx%d+%d+%d" % (width,height,x,y))
    
    root.wm_attributes("-disabled",True)
    
    top2.bind('<Button-1>', lambda e ,top=top2:flash(top))
    top.bind('<Escape>', lambda e: top.destroy())
    top.bind('<Destroy>', lambda e: [top2.destroy(),root.wm_attributes("-disabled",False)]))
def flash(top):
    print('hi')
    top.after(50,lambda: top.configure(bg='blue'))
    top.after(120,lambda: top.configure(bg='red'))
    top.after(170,lambda: top.configure(bg='blue'))
    top.after(240,lambda: top.configure(bg='red'))

b = tk.Button(root, command=top)
b.pack()

root.mainloop()

如果您有任何问题，请告诉我。
