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!

I have a program that maintains a simple, on-the-fly database using a
dictionary. The user can see what is going on with it by brining
up a
toplevel with a Text() widget. Checkbuttons and Entry fields are
used to
display the state of the items in the database (see picture).
www.passcal.nmt.edu/~bob/unlinked/images/showdb.tiff
The EN, AE, BR, etc. "flags" are the Checkbuttons and to the right
of each
TP, TO and ST label is an Entry field. Each line is one seismic
recording
instrument which this program talks to. From this 'form' the user
can
manually make changes to the state of each instrument by just
clicking the
flags or entering stuff in the fields. The problem is when there are
hundreds of instruments it starts to take a long time to open the
form and
fill it all in, scroll the form, and close the form and destroy all
of those
widgets. Is there a faster way?
What if you limit the amount of instruments shown at a time ? Does it
bring any advantage to show them all ?
Also, you could try running that app under tk 8.5, it will require no
changes and it is said to be 10% faster but I have never tested it so
maybe you can test this.
Would putting all of this on a Canvas be
faster? I'd try it, but it would take a bit of messing just to do
the
experiment -- only to find out it's not faster, plus I'm not
looking forward
to counting pixels to get everything to line up. This late-summer
we will
have an experiment with a few thousand instruments, so I'm lookin'
for a
solution. :)
Thanks!
