HI Peter, I'm glad you didn't. While I won't need it in the current
project
I'll archive it as i'm sure it will come in handy eventually.
However, rev
does not seem to be an environment that supports something like a
"main
event loop" so either you are checking the time from lots of different
places or using some other technique? (can you set an "On every 10
mins
do... handler?")
I have a "checkSave" handler triggered by any change of card or change
of background or clicking of the "print" button. The handler checks to
see how long since the last save and saves the stack if > 20 mins (or
whatever, from the preferences). I had originally thought of using a
timed loop, like:
send "doSave" to this stack in (uPrefSaveInterval * 60) seconds
but that way the save could happen in the middle of the user entering
text, so I elected to trigger it by user actions that could be delayed
by 1-2 seconds without annoying the user too much.
In general, the best way of having a "main event loop," as you called
it, is to use the "sent in time" command -- see the "send entry in the
dictionary. In this case, there would be a major disadvantage to doing
it that way.
