[Tkinter-discuss] Lots of widgets in a Text widget

[Bob Greschke]

Personally, I don't think it does any good to see any of them. The  
users will just get in there and mess things up! Haha.

I could have a different form where they enter the ID number of an  
instrument and just work with that unit. There's really no logical way  
to split them up other than like 100 at a time or something like that.  
Which one the user wants to change info for is usually just random so  
showing them all is best.  Changing things manually is only really  
done if one stops working and you need to set the broken flag or fill  
in that last field with a designation for the deployed location.

We should be updating to 8.5 next week so I'll try it out.

Thanks!

Bob
