I have a fairly long NSOutlineView (about 1000 top-level items, 2000 rows
when fully expanded since each top-level item has one subitem).
When the user selects a row and hits Delete, I want to delete that row.
There is no method for doing this directly (as far as I can tell), so I
delete the corresponding item in my data source and tell the NSOutlineView
to reloadData.
The reloadData operation takes 10 seconds. That's unacceptable; the deleted
row should just vanish, poof, instantly. My data source's replies to the
Five Big Questions are all simple one-liners. Has anyone any words of
wisdom on how to speed this up? Thx - m.
