Re: how to Progress Bar?

[Sarah Reichelt]

I guess this question has been asked a 1000 times before, but I will 
ask it again just in case you all missed it!
How do you get a progress bar to work?
I have looked for example stacks and  docs but can't find anything!

Any help would be great Thanks.................
Remember that a progress bar is just a type of scrollbar so check the 
docs for scrollbars and see what you get. The main properties you need 
are startvalue, endvalue & thumbPos. Here is an example script:

on mouseUp
  set the startvalue of scrollbar "Progress" to 0
  set the endvalue of scrollbar "Progress" to 100
  repeat with c = 1 to 100
    -- do loop stuff
    set the thumbPos of scrollbar "Progress" to c
  end repeat
end mouseUp
Drawing a progress bar takes a while, so if you have a lot of repeats, 
it's best not to draw every time you go through the loop e.g.

  repeat with c = 1 to 1000
    -- do loop stuff
    -- update progress bar every 10th time through
   if c mod 10 = 0 then set the thumbPos of scrollbar "Progress" to c
  end repeat
Cheers,
Sarah
