How to put the contents of an Array into a ListBox

Hi,
Struggling again...
What is the simplest way to take the lines of a pre-populated 1 dimensional array and put all of them into a List/Combo Box please ?
No problems populating the List/Combo Box in the IDE but I need to do it at run time.
So, I have an array populated with items depending upon the language used and I wish to populate a List/Combo Box with these items so the user may select the option they need...
I have tried various things but keep coming up with either nothing or just the first item of my array in my List/Combo Box.
This works BUt it reallyi is UGLY and awfully LONG...
Code: Select all
put 0 into N
put empty into button "lstPeople" of group "theGroup"
repeat until N= 32
add 1 to N
if gsPeople[N] is not empty then
if n > 1 then put cr after button "lstPeople" of group "theGroup"
put gsPeople[N] after button "lstPeople" of group "theGroup"
end if
end repeat
TIA
Regards.

Hi.
You are certainly on the right track, in that the contents of a combo box button will become the menuItems of that button.
Your script could be tightened, but looks sound. Ugly? Verbose, but not ugly.
Try this:
Code: Select all
put empty into button "lstPeople" of group "theGroup"
repeat with N = 1 to 32
if gsPeople[N] is not empty and N > 1 then put gsPeople[N] & cr after button "lstPeople" of group "theGroup"
end repeat
delete last char of button "lstPeople" of group "theGroup" --lose last return
No better than yours. Just shorter. There might be a lesson or two if you compare your script with mine. Is it prettier?

Hi Traxgeek,
if speed is your concern than this might be a bit faster
Code: Select all
put the keys of gsPeople into tKeys
sort tKeys numeric ascending -- get the entries sorted
repeat for each line aLine in tKeys
put gsPeople [aLine] & cr after tCollect
end repeat
delete last char of tCollect -- a return
filter tCollect without empty -- get rid of empty lines
put tCollect into button "lstPeople" of group "theGroup"
Kind regards
Bernd
edit in a prior versions were some mistakes in the code, forgot to query the array
and misspelled tCollect at one place

end repeat
Er... no... you'll miss the first key that way.

His script also ignores the first key.
TraxGeek, is this what you wanted?
Anyway, I was after beauty, not truth.

Superb.
Thanks a million - both of you.
Perfect demo of the 'Repeat WITH'
For some reason, I hadn't appreciated this 'with' part... excellent.
And 'delete last char of [some variable/control]' is much neater / faster than my doing an 'If' each and every pass through my loop/repeat block.
Truly - thanks a million guys. Much appreciated.
Regards.

Craig-
No, the OP just doesn't put a leading cr before the first entry.
It *does* put every array key into the list.
But you got the point across.
Traxgeek-
The "repeat for each" form is much faster than the "repeat with" form.
You can probably (untested right now) also make a one-liner to do the whole thing in one swell foop:
Code: Select all
put the keys of gsPeople into button "lstPeople" of group "theGroup"

Mark..
Not sure what you mean. traxGeek's script ignores the first key, and I did not change that. But generically:
repeat with y = 1 to 4
put random(99) & return after btn "combo"
delete last char of btn "combo"
end repeat
puts four numbers (menuItems) into the button. What were you saying about not putting a cr before the first entry?
Just wondering.

It doesn't matter how many times you say it, it's still wrong.
Are you and I looking at the same piece of code in the first post?

No, I was looking at much later ones.
Never mind...

Ah, ok, mystery solved.
