The most likely solution, off the top of my head, would involve
subclassing the NSOutlineView and overriding some method to tell Cocoa
to indent some rows more than others.
Here is one possibility. I don't know that it works, but it might.
Try it and see.
// you would need to subclass NSOutlineView, if you haven't already
and override this method
- (NSInteger)levelForItem:(id)item
{
NSInteger level = [super levelForItem:item];
if ([item needsExtraIndenting] == YES) // whatever your test is here
level++;
return level;
}
Another possibility would involve overriding something else, maybe
like this:
- (NSRect)frameOfCellAtColumn:(NSInteger)column row:(NSInteger)row
{
NSRect rc = [super frameOfCellAtColumn:column row:row];
if ([[self itemAtRow:row] needsExtraIndenting] == YES) // whatever
your test is here
{
CGFloat indent = [self indentationPerLevel];
rc.origin.x += indent;
rc.size.width -= indent;
}
return rc;
}
Again, I don't know that this works, but this is the type of solution
I would look for first. Look through NSOutlineView.h and
NSTableView.h for interesting methods that you can override and
customize. That's what I did to find these two.

Is there a way to indent main headings in NSOutlineView as follows: -
Heading 1
Item
Item
Heading 2
Item
Heading 2.1
Item
Item
Heading 3
Item
I tried many ways to indent the headings but not succeeded. The
disclosure triangle doesn't indent with headings. I required heading
within heading and the heading should be independent of its parent
heading. The parent heading may contain any number of items within.
