ApplescriptObjC: scroll down text view

Question

Hi Community,
I'm making a data management program in ApplescriptObjC, and rather than using a progress bar alone to display progress, I want to use a text view as a log to relay information (much like terminal does when running a command in verbose mode). The only problem is that once the "log" fills up, it doesn't scroll down, it stays at the top. Is there any way to set the setString so that it will start at the bottom?

Answer 1

Just a quick question about the actual "log" though. Here's the code I have for it, and i'm calling on it with a test button right now, but it doesn't seem to be working. Do you know what i'm doing wrong? Here's what I have:
  on test_(sender)
       repeat with i from 1 to 10
            ProgReport_("test " & i)
       end repeat
  end test_
on ProgReport_(NewProgress)
     set oldProgress to oldProgress & "
" & NewProgress
     prog's scrollRangeToVisible_({length of oldProgress, 0})
end ProgReport_
