I don;t jhave time to look at this in detail just now, maybe later.
But first impressions is that you have a very unorthodox style of
Tkinter programming. Its more traditional to build the entire GUI
up front rather than creating and destroying widgets each time you
execute an event handler. Its less disturbing to the user than
having things appear/disappear etc, as you seem to be doing.
You can make widget hide/show/deactivate themselves without
destroying them just by withdrawing/unpacking them etc or
changing their status, if that's really what you want to do.
The code does not wait till the function returns a value, resulting in
the signcount variable in having a None value, giving an output like
below.
I'll look at this a bit more closely later if nobody else
answers by then...
This is where you call your function. Looking at it quickly
I think you would be as well using the standard Tkinter
simpledialogs/messagebox modules to get user input.
Have you looked at the simpledialogs?
Thank you Alan, I didn't know of simpledialogs. That was all I needed to
search documentation for these. I have
now achieved what I was trying to do, with user interface as I was planning.
Or better still having a static entry field on your GUI
and just reading that?
I'll have to figure out how to achieve that!
Perhaps my intended design is not in line with modern styles?
