Jacqueline,
I'm trying to start at a very basic level - first of all to understand
how to apply the 'selectedChunk' which seems crucial to my whole
problem.
My script looks right to me but throws up an error -surprise, surprise.
I understand the principle of what selectedChunk achieves, but how to
test
for that is not immediately apparent to me. Although the 'Documentation'
references describe the various functions, I find them not descriptive
enough.
They each really need a complete example so that the snippet can be seen
in some kind of context. This is not adequate for me, as it does not
show
how to retrieve and startChar or endChar values...
the selectedChunk
put the selectedChunk into storedChunk
I'm afraid even this basic stuff stumps me at the moment.
on keyDown theKey
if the selectedChunk (theKey, field "insertionField") is -1 then
answer "endChar is -1"
else
if the selectedChunk (theKey, field "insertionField") is +1 then
answer "endChar is +1"
else
if the selectedChunk (theKey, field "insertionField") is 0 then
beep
end if
end if
end if
end keyDown
What am I missing?
Many thanks,
Adrian

Martin,
Thanks for your suggestion. It did not work for me - reporting:
Type Function: error in function handler
Object edtText
Line put Lookupchar(char beforecharpos of me) into newbeforechar
Hint Lookupchar
Martin was assuming you would write your own function "lookupchar" to
do the actual work, but since you are new at this, the function is
actually exactly what you are asking about.
The object field is "edtText" but if I change me to edtText
that throws up an error too.
To reference a field, you'd need to add the object descriptor. That
is, change "me" to "field 'edtText'". But "me" is okay, leave it that
way as long as the script is in the field itself.
To explain a little more why the cursor position is important...
User entering text can be dealt with as keyDown.
But if User goes back and inserts cursor in an existing word,
I need to know what is either side so that those characters can
be matched against a list and replaced if necessary.
Look up the "selectedChunk" term in the dictionary. This gives you the
position of the insertion point, or the position of any selected text,
in the format:
char x to y of field "whatever"
If x is smaller than y, a range of characters is selected. If x is
larger than y, the insertion point is blinking between two characters.
Your script should check to see whether x is smaller than y. If so,
you've got a selection that spans characters, and x-1 would be the
previous character, and y+1 would be the next one. If x is larger than
y, the insertion point is between characters and x+1 would be the next
character and y-1 would be the previous one.
Once you have determined whether you have a range of text or not, you
can put extra text either in front of or after the selected chunk:
put "abc" before char x of field "whatever" -- works for a range
put "abc" after char y of field "whatever" -- works for a range
put "abc" before char y of field "whatever" -- for non-range
put "abc" after char x of field "whatever" -- for non-range
