I have done it, but I can't share the stack, it's too embarrassing.
It's a very old one, and partly was developed in 1.1.1 tester version,
so has code split all over the place, to adhere to the 10 line limit.
What it did was basically send the next field in the row the line
clicked, and that field then would decide which content to show based
on that. If you arrange list fields, and name them in a successive way
(eg: "column 1", "column 2",...) then you can just add one to the
current field, and know which the next should be (send "ShowLines" &&
the selectedtext of me to field ("column" && word 2 of the short name
of me+1")).
Then to hide all fields that are not needed, you'd do the same, but
invoking a handler that hides that particular field, and every one
above (untested):
on hideCols --in every fields script
hide me
if there is a field ("column" && word 2 of the short name of me+1)
then
send "hideCols" to field ("column" && word 2 of the short name of
me+1)
end if
end hideCols
As an added exercise I did not do (I just arranged 10 fields and was
glad it worked (also there was a bug with clone setting the cursor back
then)), you could check every time if the next field exists, and if
not, clone the field currently the last one, setting the location
correctly, and changing the name to ("column" && word 2 of the short
name of me+1).
Watch out if you put the fields into a horizontally scrollable group,
if the group is scrolled, the fields locations change, so use relative
positioning, not absolute. You can also scroll the group to show
exactly the last visible field, if a user chooses a line, and be better
then the OS X finder (which is horribly wrong often (if it scrolls at
all)).
As for "editing in the same way", do you mean the way the finder does
file renaming? If yes, just make one editable field, and if a line is
double clicked, put that field over the line, covering it completely.
If the user hits return or clicks outside the field, put the contents
of the field into the correct line of your column field. It'd look and
behave quite similar.
Have fun

I want to display a hierarchy (think: outline) in the way that the Mac
Finder does with column view. Note that I am NOT interested in
displaying files and folders, rather outline text. I also want to be
able to edit the text in the same view.

Has anyone done this already in a Rev stack?
