Pete,
in a scrolling editable field with columnar data delimited by tabs of the
form
data tab data return
data tab data return
i.e. no additional tab before the return
the following code works for me for the tab key and shit-tab key to move
from one item to the other (tested in 6.6.2, 6.7DP7 and 7.0DP8)
-------------------------------------------------
on tabKey
set the itemDelimiter to tab
put the selectedChunk into tSelect
put word 2 of tSelect into tIndex
put the number of lines of char 1 to tIndex of me into tCurrLine
put (the number of chars of line 1 to tCurrLine - 1 of me) + 1 into
tChars
put tIndex - tChars into tLineChar
put the number of items of line tCurrLine of me into tNoItemsInLine
put the number of items of char 1 to tLineChar of Line tCurrLine of me
into tCurrItem
if the shiftKey is down then
if tCurrItem = 1 then
if tCurrLine > 1 then
select after item (the number of items of line tCurrLine - 1 of
me) of line tCurrLine - 1 of me
end if
else
select after item tCurrItem-1 of line tCurrLine of me
end if
else
if tCurrItem = tNoItemsInLine then
select after item 1 of line tCurrLine + 1 of me
else
select after item tCurrItem + 1 of line tCurrLine of me
end if
end if
end tabKey
--------------------------------------------
the difference of the two scripts has to do with how LC counts items across
lines and within a line.
I would rather not like to start a discussion about how items are counted...
Kind regards
Bernd
