Hi Gerriet,

So what I need is obviously something like: (void) justBeforeTheNextDisplayScrollRangeToVisible:(NSRange)aRange

Is there something like this? Or what can be used instead?

You could make a subclass of NSTextView with your method (or just override -scrollRangeToVisible:). When it's called, you'd save the range in an ivar and call [self setNeedsDisplay:YES]. Then when - drawRect: is next called, check if you have a range set and, if so, call [super scrollRangeToVisible:] and return. Or something like that.

Instead of overriding -drawRect:, you could listen for NSWindowDidUpdateNotification and do the scrolling then.
