What could cause an open file dialog window in Tkinter/Python to be really slow to close after the user selects a file?

Question

I can do the following in my program to get a simple open file dialog and print the selected file path. Unfortunately it doesn\'t go away right away when the user selects t

Answer 1

Exactly the problem I had - sometimes the file dialog would go away after a while, sometimes not. But it always seemed to block a later status windows. Adding the root.update() fixed both problems immediately.

Answer 2

I was having some trouble with Tkinter dialog boxes. Like you, the dialog just sat there after I had selected a file. I didn't try leaving it for very long, it may have disappeared after 5 minutes as you said your's did. After lots of random experimentation I found that calling root.update() before the askopenfilename() line seemed to fix it.

For reference, this is the code I was testing with:

import sys
from tkinter import *
from tkinter import filedialog

#instantiate a Tk window
root = Tk()

#set the title of the window
root.title('Tk test')

#dunno what this does, fixes askopenfilename if I use it.
root.update()

print(filedialog.askopenfilename(title='dialogue? surely.'))
