I've found that when a toplevel widget calls a messagebox dialog (like "showinfo"), the root window is showed up, over the toplevel. Is there a way to set the Toplevel window as the master of the messagebox dialog ?
Here is a script to reproduce this :
# -*- coding:utf-8 -*-
# PYTHON 3 ONLY
from tkinter import *
from tkinter import messagebox
root = Tk()
root.title('ROOT WINDOW')
Label(root, text = 'Place the toplevel window over the root window\nThen, push the button and you will see that the root window is again over the toplevel').grid()
topWindow = Toplevel(root)
topWindow.title('TOPLEVEL WINDOW')
Label(topWindow, text = 'This button will open a messagebox but will\ndo a "focus_force()" thing on the root window').grid()
Button(topWindow, text = '[Push me !]', command = lambda: messagebox.showinfo('foo', 'bar!')).grid()
# --
root.mainloop()
You can set the parent
argument to topWindow
for the showInfo
command:
Button(..., command=lambda: messagebox.showInfo(parent=topWindow, ...))
