[issue26377] Tkinter dialogs will not close if root window not packed.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Looking at #26376 again, I think Ned's msg260413 identified Sam's problem.  
"Also note that installing ActiveTcl 8.6.x has no effect if the tkinter in use 
was linked with an 8.5 version of Tcl/Tk, as the one you are using apparently 
was. Make sure you have installed the latest version of ActiveTcl 8.5.x and try 
again."  Sam's tk 8.5 would have been Apple's buggy 8.5.9 (or earlier).  I 
should have asked for the 8.y.z version listed in About IDLE.

In any case, I also verified no problem in current Python-Tk-IDLE.

Is this problem still present?

I've used the following script to test:

import tkinter
from tkinter import messagebox

root = tkinter.Tk()
box = messagebox.showinfo("Title", "A Message")

# -- EOF ---

With this script I can close the message box without problems (by clicking on 
the OK button). Both when running from the command-line and when running from 
IDLE.

Python 3.9, installer from python.org.

Sam Yeager added the comment:

Updated script with the adding 'parent-Rootwin' to messagebox() arguments. The 
issue persists.

Following advice in #26376:
Ran script on Terminal. The issue disappears, and everything works normally.
Running through IDLE, the issue returns.

Try adding 'parent=rootWin' to the messagebox call.  Otherwise, I expect that 
this is, as far as cause, a duplicate of #2637, in which case my comment 
https://bugs.python.org/issue26376#msg260544 applies.

[issue26377] Tkinter dialogs will not close if root window not packed.

[Sam Yeager]

New submission from Sam Yeager:

Using the following code, the messagebox will not close, leaving it on top of 
all other open windows:

from tkinter import *
rootWin = Tk()
messagebox.showinfo("Title", "foo")


If the root window contains a widget (Label, Entry, Button, etc.), the dialog 
can close.
Similar results have been obtained with filedialog.
