Issue between CTkListbox super().bind_all and tk bbox call

[tsouzadaSSA]

Hej!!

I have updated the CTkListbox and I am getting this error:

Exception in Tkinter callback Traceback (most recent call last): File "C:\Users\tsouzada\AppData\Local\Programs\Python\Python39\lib\tkinter__init.py", line 1892, in call return self.func(*args) File "C:\Users\tsouzada\AppData\Local\Programs\Python\Python39\lib\site-packages\CTkListbox\ctk_listbox.py", line 115, in super().bind_all(key, lambda e: func(self.get()), add="+") File "C:\Users\tsouzada\AppData\Local\Programs\Python\Python39\lib\site-packages\customtkinter\windows\widgets\ctk_scrollable_frame.py", line 75, in self.bind("", lambda e: self._parent_canvas.configure(scrollregion=self._parent_canvas.bbox("all"))) File "C:\Users\tsouzada\AppData\Local\Programs\Python\Python39\lib\tkinter\init__.py", line 2731, in bbox self.tk.call((self._w, 'bbox') + args)) or None _tkinter.TclError: invalid command name ".!ctktabview.!ctkframe.!tab_environment.!ctkframe.!sidebar_environment.!ctkframe.!ctkframe.!canvas"

And I saw there was an update kind of related to that (https://github.com/Akascape/CTkListbox/commit/991da89d5a4fde8dde5c3db22c398fe241f76e40) Have you seen this kind of issue or do you have an idea what it could be about? This error happens when closing the CTk window

CTkListbox 0.7 customtkinter 5.2.0

@tsouzadaSSA Not experiencing this issue. Maybe related to your environment. Is it showing the error with the basic example?

[tsouzadaSSA]

No, it is not. Thank you for your attention! I will continue debugging to understand were I messed it up

Hey, @Akascape

I managed to get the way to reproduce and it is quite specific. The issue can be reproduced if you have a window with a CTkListbox and a CTkTabview with another CTkTabview inside one of the non-selected tabs. Then the issue happens if you close the window without selecting the CTkTabview which has the CTkTabview.

So, given the script: A CTkListbox beside a CTkTabview with 3 tabs: "A", "B" and "C". The tab "B" has another CTkTabview with 1 tab "B1".

To have the issue being reproduced you just need to run the script, then close the window (without clicking in the tab "B"). The result is:

But if you run the script and click in the tab "B", there is no issue.

Have you seen this before?

The script if you want to try it: import customtkinter from CTkListbox import *

class APP(customtkinter.CTk): def init(self, test_mode=False): super().init()

    self.listbox = CTkListbox(self)
    self.listbox.pack(fill="both", expand=True, side="left")

    t1 = customtkinter.CTkTabview(self)
    t1.pack( expand=1, fill="both" )

    t1.add("A")
    t1.add("B")
    t1.add("C")

    B = customtkinter.CTkTabview(t1.tab("B"))
    B.pack( expand=1, fill="both" )
    B.add("B1")

    self.mainloop()

def main(): APP()

if name == "main": main()

Hello!

I'm jumping in here with the same issue if you don't mind. I get the same error that repeats a few times when I close my project. I'm running the same version on windows10. I don't get the error when running the example.py

I removed my CTKlistbox in my tabview but didn't work...

I switched back to a tkinter listbox for now but have my project up if you're interested in trying to reproduce the error. Just switch back to CtkListbox on line 52 in views/home_view.py and line 29 and 34 in controller.py

I'll keep playing around, let me know if you find a fix! this widget is much better looking

[codedreamin]

This actually happens for me as well, in my case, I have a few listbox's inside of a tabview, if I don't click on all of the listbox's before closing the window I get this same error message.

@BAndresen @codedreamin @tsouzadaSSA Guys, I have tried to fix this issue, please update to the latest version and let me know...

pip install CTkListbox --upgrade

[tsouzadaSSA]

@Akascape you rock! Fixed here!

[BAndresen]

@Akascape works for me, thxs so much!

[codedreamin]

@Akascape

I'm still getting this error for bad window path name ".!ctktitlemenu", but I no longer get any other errors, so it looks like it is mostly fixed.

[Akascape]

@codedreamin That error is causing due to ctktitlemenu. But the issue is similar.
