Thanks for the tips regarding a field which number of lines stays
constant but allows the user to add and delete characters.
Kevin�s tip for trapping the backspaceKey message works very well:
on backSpaceKey
put word 4 of the selectedChunk into tCharNo
if charToNum(char tCharNo of me) is not 10 then pass backSpaceKey
end backSpaceKey
I added a similar script to trap the deleteKey message:
on deleteKey
put word 2 of the selectedChunk into tCharNo
if charToNum(char tCharNo of me) is not 10 then pass backSpaceKey
end deleteKey
which deletes characters "forward" but not return characters.
Actually the suggested script for taking the cursor one line down in the
field instead of adding a new line in the field does�nt work:
on returnInField
put word 2 of the selectedLine into tLineNo
add 1 to tLineNo
select before line tLineNo of me
end returnInField
when I press the returnKey there are still lines added to the field.
Instead of this I now use:
on returnInField
put the number of lines of fld "names" into numlin
put the initLineNum of this stack into initVal # custom prop to store
the initital number of lines
if numlin = initVal - 1 then exit returnInField
else pass returnInField
end returnInField
Thanks again for the tips
