I've modified Xavier's modification of my modification of
(somebody's??) code to search incrementally in a sorted list field.
(This version, unlike Xavier's, assumes the whole line in the field
is the sorted item.)
But it doesn't solve one problem: suppose the user starts typing a
string that doesn't appear in the list? If the first few letters
match something, this scrolls to pretty close. But suppose nothing
starts with 'Q' and the user starts by typing a 'q'? The list won't
scroll at all. What would be nicer would be to scroll to the place
where an item beginning with 'q' *would* be if there were one. I've
only thought about it for a few minutes, but it's already given me a
headache. Any clues?
local kTyped, lastKeyTime
on keyUp theKey
if lastKeyTime is empty or the seconds - lastKeyTime > 3
then put theKey into kTyped
else put theKey after kTyped
put the seconds into lastKeyTime
put lineOffset(CR & kTyped, me) into lo
if lo is not 0
then set the scroll of me to lo * the effective textHeight of me
end keyUp
