Error with .set(name) after destroying Tabview

[PrizeGotti]

In my application, I need to destroy the tabview to reload it with updated labels.

This all works fine except when I try to set the visible tab back to what it was before I destroyed the tabview.

I get the following error:

_tkinter.TclError: bad window path name ".!ctkframe2.!ctktabview.!ctkframe"

How can I fix this issue so I can set the visible tab back to the correct one?

Many thanks!

When I run either the "add_doc" or "del_entry" functions, I get the following errow when I call "tabview.set(tname)" in either function.

Many thanks!

First: thanks for sharing code to reproduce the issue. 😄

Second: If this can not be shortened (really?), then at least fix the code boxes for better readability, this might be helpful Creating and highlighting code blocks. Thanks.

[PrizeGotti]

My apologies, I'm new to github and trying to get a grip with its formatting (overly complexed in comparison to other sites).

Hopefully that's easier to read. I thought it was best to provide the whole code so you can see what steps are taking place.

[Wolf-SO]

No need for apologies, we all are just learning. It's easier to read, definitively. I'll have a deeper look on this soon…

[Wolf-SO]

The example you gave is too complex. It needs several files to work: Symbol image, Excel file, font, etc. Please try to reduce it step by step, but keeping the error.

When I use AntoDock to dock molecules, this error occurs when generating a. blg file. How can I solve this problem?
