I have a situation where I need to temporarily set the array controller's content to nil, mess with the content, and then hand it back to the array controller, and I'd like to preserve the scrolling position. I thought I could just get the value of the NSScroller before, and set it back after, but that results in the scroll bar being out of sync with the actual scrolling state of the table. How can I do it?
Maybe something like this (typed in Mail):
clipOrigin = tableView.enclosingScrollView.contentView.bounds.origin;
... change the table then put it back again ...
[tableView.enclosingScrollView.contentView scrollToPoint: clipOrigin];
This first line is kind of a guess, based on the documentation for 'scrollToPoint:'.
