[comp.sys.mac.programmer] TrackControl question

dieter@oahu.cs.ucla.edu (Dieter Rothmeier) (07/18/88)

How frequently does TrackControl call its actionProc whose address was
passed in as a parameter? Is the frequency modifiable?
I am writing a little program that, among other things, scrolls text,
and when I click a scroll arrow, the text always scrolls 3 or 4 lines.
I want to be able to scroll one line at a time.

Thanks in advance,
Dieter Rothmeier

To reduce the scroll rate, I just put a call to delay some small
number of ticks before returning from the filter proc.  Works for me.
