Hi, everyone. After extensive archive searching, I've come across
nothing that relates to this simple (or so I might think?) idea for
outline view sorting.
Take Apple's OutlineEdit example--run it. Enter some to-do items,
click the first column header, and *poof* it's all sorted, neat and
tidy. Add a new entry--it does not wind up placed correctly
(alphabetically). Changing existing entries does not cause automatic
reordering, either.
The NSTreeController method -rearrangeObjects fails to do anything
that I perceive as useful--apparently it's just for subclasses?
I have an outline view with a single column. It contains strings in
a nested hierarchy of modelled entities that have combined leaf/node
structure (if that's what you'd call it)--a single entity has
children, all of whom are of the same entity type.
I have tried all manner of connections with sortDescriptors and other
bindings. If I would like my outline view to be sorted
alphabetically 100% of the time and to perform automatic, 'live'
resorting whenever a single entity is edited, what's the best (i.e.,
most efficient and not-too-abstruse) way of doing this? (I don't
mind if I have to go to leaf-node, but it seems like overkill?)
Many thanks,
Andrew
