You can use the method
[ outlineview isItemExpanded:parent ]
to check the state of the parent item.

Hi all,
I have a subclass of NSImageCell that displays a progress indicator in
addition to images. The problem I'm having is that I have no idea when
the cell is hidden by the outline view, like when the parent item is
collapsed. So I end up with the progress indicator spinning out in
empty space. Is there any way to find out when my cell shouldn't be
drawing?
Thanks,
Glen

Discussion after watching Disney's "Lilo & Stitch":
DAD: "But why did the space aliens speak English, as opposed to French,
or Swahili? And why did the one alien speak English with an Eastern
European accent? I don't get it."
