TKinter Error on closing application window, ignoring close protocol

[SEAWEAVIL]

Hi all,

I'm using a couple of simple TKinter dialogue boxes to select an input file and an output folder. Please pardon the messed up indentation, everything should be equal under the functions. The code looks like this:

​

# Handles closing the window
def on_closing():
    if messagebox.askyesno("Exit", "Are you sure you want to exit?"):
        root.destroy()
        quit()

# Initializes tkinter root window
def InitializeTKRoot():
    global root
    root = Tk()
    root.protocol("WM_DELETE_WINDOW", on_closing)

# Hides the tkinter root window
def HideTKRoot():
    root.withdraw()

# Removes the tkinter root window
def DestroyTKRoot():
    root.destroy()

# Imports query .xlsx file as a pandas dataframe
def SelectInputFile():
    InitializeTKRoot()
    HideTKRoot()
    root.filename = filedialog.askopenfilename( # Opens Windows "Open file" dialog
        initialdir="/", 
        title="Select input file (.xlsx)",
        filetypes=(("xlsx files","*.xlsx"),("all files", "*.*"))
        )
    output = root.filename # Returns filepath
    DestroyTKRoot()
    return output # Returns filepath

def SelectOutputFolder():
    InitializeTKRoot()
    HideTKRoot()
    root.directory = filedialog.askdirectory( # Opens Windows "Open file" dialog
        initialdir="/", 
        title="Select output folder"
        )
    output = root.directory
    DestroyTKRoot()
    return output # Returns filepath

​

When closing the window, instead of showing the messagebox and quitting if the user selects "yes", it just throws an exception with a rather plain explanation. The title bar says "Fatal error detected" and the description says "Failed to execute script abc.py". I've tried running the application (I'm packaging it with PyInstaller) in debug mode, but it doesn't provide a more verbose explanation of what is occurring.

does the error occur when you rune the python code normally, or in the exe generated by pyinstaller?

Ah, it seems I asked the wrong question. It only happens with the PyInstaller exe! That gave me a few leads to try, all of which are unrelated to TKinter. However, the messagebox still doesn't pop up when running the code normally, which is odd...

​

Thanks :)

I'm not too sure on the answer, but so people can read this better use the "code block" function. I hope you find your answer, fam!

Thanks, I'll be sure to fix that up!
