Please read my first posting again (or at all), everything is in there!

Result with NO text selected in a field: char 2 to 1 of field 1 -> word 2 > word 4!
Um . . . well, yes, possibly.
But still bloody bad logic.

Because the selectedChunk returns:
for a blinking cursor, and a range if an actual selection of multiple chars.
But it is word 2 that matters
Klaus had this as well.

Will work with parens:
Will work without as well. Parens likely more readable.

Because the selectedChunk returns:
char 5 to 4 of field 1
So it does.
Daft logic whichever way you slice things.

Richmond.
For the selectedChunk in a fld 1:
If you have selected char 4 to 7 of "123456789", you get "char 4 to 7 of field 1".
If you have selected char 4 of "123456789", you get "char 4 to 4 of field 1".
Now say you only have the insertion point after char 4. By "daft", do you mean why don't you get "char 4.5 to 4.5 of field 1", instead of what you do get, which is "char 5 to 4 of field 1"?

No: by daft I mean that 'char 5 to 4' goes backwards, and
neither char 4 nor char 5 are selected.

By "daft" I mean everybody here, especially me.
You must:
Code: Select all
on rawkeyDown tKey
if tKey = 65535 then delete char word 4 of the selectedChunk + 1 of fld 1
end rawkeyDown
NOT word 2.
It is just the way the selectedChunk works.

So, and I am only partly serious, and only mostly daft, would you do the "char 4.5" thing?
What else would do?

Hokey. Period.

neither char 4 nor char 5 are selected.
If they weren't backward, you would be talking about char 4 to 5, no? A simple chunk.
So how do you identify the position of a blinking cursor? It is indeed between 4 and 5, but not exactly either, eh?, and so, decimals (4.5) notwithstanding, it was decided to run the char positions backward.

Hi,
try this:
Code: Select all
on mouseUp
get the selectedchunk
if it is empty then exit mouseUp
put word 2 of it into myStart
put word 4 of it into myEnd
put word 6 to -1 of it into myTarget
if myStart > myEnd then
put "delete char " & myStart & " of " & myTarget into myCmd
else
put "delete char " & myStart & " to " & myEnd & " of " & myTarget into myCmd
end if
do myCmd
end mouseUp
Have fun!

This is a direct port of HC syntax, so blame Apple. It allows you to determine whether an actual selection exists or just a cursor insertion.

Think of it this way:
The first number indicates the start of the selection highlight (i.e. the left of the indicated character)
The second number indicates the end of the selection highlight (i.e. the right of the indicated character)
So with that definition, the cursor (selection) is precisely defined by those 2 positions as being between the characters.

Brian.
Richmond was on about the order of start and finish values in the selectedChunk (for a blinking cursor) being backwards. Where:
equals "0", This is yet another way to determine whether one or more actual chars are selected, or only a blinking cursor lives in the text.
The start and finish values, as you posted, are reversed in this case. They would only apply to actual selected chars, not a cursor. He thinks this is daft.
