I have a CoreData app with an NSTableView, and I want the user to be
able to
add and delete the columns (from a given list). I've been able to
programmatically
recreate all of the columns and their bindings except the ones that
use a custom
NSValueTransformer and NSPopUpButtonCell. My questions are
1) How do I bind the value transformer? I haven't been able to
figure out how
from the documentation or examples on the web.
2) How do I control the appearance of the popUpButtonCell? The
initial version
(that I get from setting things up in IB) uses the style from IB's
Cocoa-Data
palette, but the programmatic version comes back with one looking
like the
one in the Cocoa-Controls palette. It looks clunky inside a table view.
I'm using XCode 2.4.1 and IB 2.5.4 on OS X 10.4.11.
Thanks,
Norm Hecht
