is it possible to count the letters (countdown from 160 to 0) in a NStextfield and erease this textfield by clicking a button?
Background: I want to send sms messages which are not longer than 160 letters!
if name of theObject is "sms_delete" then
set contents of text view "text" of scroll view "text" of tab view item "Outbox" of tab view "tab" of window "main" to ""
end if
on changed theObject
set remainingChars to 160 - (length of (get theObject's content))
set content of text field "counter" of window "main" to remainingChars
if remainingChars < 0 then
set theObject's content to (text 1 through 160 of (get theObject's content))
beep
set content of text field "counter" of window "main" to "0"
end if
end changed
