Sorry, forgot to add something (that my tree controller binds to Core Data).
-----
I found two examples so far (one using notifications, one KVO) for responding
to changes in a table view's selection.
I tried the KVO approach in the sample code NSTabelViewBinding. It sets up KVO
on the array controller:
[myContentArray addObserver: self
forKeyPath: @"selectionIndexes"
options: NSKeyValueObservingOptionNew
context: NULL];
I tried to do the same on my NSTreeController, but I'm not getting called. What
do I need to do?
My tree controller binds to Core Data.
TIA,
Rick
