Search the docs for -scrollRectToVisible: and -scrollToPoint:

p.s. since I know you're doing this in DK, also look at DKDrawing's -
scrollToRect: method, which you should use.

Hello All,
I've implemented a sort of "time zoom" for a music app I'm working
on. Basically, it's just re-positioning objects along a musical
staff when I click and drag up/down the screen (like in Live, or
Logic... Soundtrack too, I think). However, if I'm in the middle of
a score, the content I'm looking at quickly flies off the right side
of window, because the zoom is obviously making "time" occupy more
horizontal space, and shifting notes in the middle of the score off
to the right. I'd basically just like to scroll the view in such a
way as to keep the area of score I'm trying to zoom in on in view...
I'm sure it's not very complicated, but any help would be appreciated.
thanks,
J.
