I don't know (now) how to solve your challenges below. But if I were trying to figure this out, I would try to find more complex tkinter example applications that contain some of the issues I'd be interested in. Then I would dig into the code, find the relevant pieces, and then start playing with them until I understood them. I know Alan suggested some resources in one of your earlier threads. One of the books he suggested was, "Python and Tkinter Programming" by John E. Grayson. It is a fairly old book from the Python 2 days, copyrighted 2000. However, I own this book and have gotten a lot of use out of it. He has _lots_ of complete examples, including such things as a scientific calculator that looks like something HP sells! The other book, "Programming Python" by Mark Lutz has a very large section on tkinter with plenty of examples. I have gotten much good use out this book as well. It is much more recent, covering Python 3 (and mentions Python 2 differences as well). And then there is the Internet. Surely you could find relevant material out there. Maybe even the source code for IDLE would be helpful. I understand it is written using tkinter.

It sounds like it breaks down to two different types of key bindings: (1) Binding some keys (perhaps the arrow keys) to change focus from cell to cell; and, (2) binding keys to do the actual numerical data entry in each cell. > A second experiment involved the earlier grid of entry boxes but with a space > between every third row and column.

I don't know if would be helpful or not for you in your use case, but perhaps it is something to think about. In the Grayson book he has lots of examples of achieving very precise spacing and placement of widgets, etc. Just some thoughts. Perhaps they might inspire a creative thought or two. Of course one of the experienced tkinter pros out there might chime in with very detailed, specific help. -- boB _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
