Are you calling setAutosaveName: yourself? Set it to nil in the nib.
Then, call it yourself. Before you call it, print out all the table
columns to see what they are. Then, load your tablecolumns that you
want (add new ones). Then call setAutosaveName:<something>. Change the
width of a column in your GUI. This should save out the autosave
values. Quit your app. Restart it. Are the columns restored?
This pattern should work; I use it internally in the open and save
panel.

Thanks for the suggestion -
I tried calling setAutosaveTableColumns: after adding a column from
code, but on next launch it only showed the columns that are defined
in the nib with IB.

If you add all the columns (and remove old ones) before calling
setAutosaveName:, or setAutosaveTableColumns:, then it should work
out okay; it will restore all of the widths, positions, etc.

I'm working on an application that will allow users to add columns
of descriptive information to an NSTableView - the available
columns are determined at launch time by loading a dictionary.
In my test app, I can add columns to my table no problem. Now I
am trying to decide on a robust and efficient way to make sure
that the set of columns chosen by the user, and their geometry, is
saved when quitting the app and restored at the next launch.
I can think of a number of brute force ways to do it - save an
array of column identifiers and/or value bindings to user
preferences, for example.
I know it's possible to autosave column layout information under
Leopard through the framework, and this appears to work. The
autosave info appears to restore the geometry of columns defined
in the nib file, but it won't force a reload of columns created
programatically in the last session. I suspect that the autosave
file may actually contain the identifiers of all columns displayed
as of the last application quit, and wonder if there is a way,
during nib loading, to access this list so I can initialize the
table.
I don't like having the same information stored multiple places
(i.e. my own NSArray in user prefs replicating info that might be
more complete in the NSTableView autosave file) if I can avoid it,
but can't seem to find a way to get at all the info in this file.
If anyone has some good examples of how this can be done, or some
past experience to share on what works well, I'd be very grateful.
