On a slightly related topic, some time ago, I wrote this:
- (NSView *) ancestorViewOfClass:(Class) aClass
{
NSView
*result = self;
while (result = [result superview])
if ([result isKindOfClass:aClass)
return result;
return nil;
}
..in a category of NSView to simplify walking up a view hierarchy to
find (say) the scrollview or splitview or whatnot that contained the
receiver. This way, I don't need to keep track of how many steps back
up the chain it is to the view I want.

Hmmm.
This used to drive me mad, too. Until I realized that you need to set
the sizes of the actual subviews of the split view. Sort of like this
(myTableView is one of the two things I put in the split view):
[[[myTableView superview] superview] setFrame: myFrame];
Since the first superview of a table view is a clip view and the next
is the scroller, and it is the scroller that is the direct subview of
the NSSplitView and is the one you need to set.
For a textedit, it is even worse:
[[[[myTextEdit superview] superview] superview] setFrame:
myTextEditFrame];
Of course, remeber to set the frame sizes _exactly_ right, so the
hights of the frames and the divider together fill the entire height
of the BSSplitView. (But I guess you already knew that, huh?)
Also, be sure to let the window resize itself _before_ calculating the
frame sizes and calling -adjustSubviews (like if you open the Window
and resize it programatically before showing, you dont want to call
-adjustSubviews in the windowDidLoad or awakeFromNib.)
Hope this helps. (Someone please tell me if I'm wrong! I'd actually
like to be wrong in this case! :)
