Apple has a sample app called DragNDropOutlineView that's helpful when
getting comfortable with outline views. Also, Jonathan Dann has two
useful outline view sample apps -- one to show sorting with Core Data
and another that animates the expansion of a root object to reveal its
contents (Animating Outline View). His site is http://espresso-served-here.com/

I am looking for some code to make the root object's in an outline

I am pretty sure I need to sub-class the outline view but I don't
know what code to add to the sub-class to do what I want it to do
(which is what I described above).
There shouldn't be any need to subclass the outline view -- you will
most likely be able to set the desired background color in
outlineView:willDisplayCell:forTableColumn:item: (and/or
outlineView:willDisplayOutlineCell:forTableColumn:item:).
Another possibility, if it's important that the top level object
rows need to look different but it's not crucial that you use a
specific background color, is to implement outlineView:isGroupItem:
(another delegate method), which gives group rows a distinctive look.
