How to use a DataSource for NSLevelindicatorCell?



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

May somebody please tell me, what I'm supposed to return in the "- (id)tableView:(NSTableView *)aTableViewobjectValueForTableColumn: (NSTableColumn *)aTableColumn row:(int)rowIndex" method of my table view's data source, for a column consisting of NSLevelIndicatorCells? I only dragged them into the table, but couldn't find any documentation, showing how to set their value. Is there any documentation on how to use them?

Thanks in advance,


Paul.

P.S.: Sorry, if this question is silly, but I'm quiet new to Obj-C and Cocoa.
