Return Value
The string that is used for type selection. You may want to change what is searched for based on what is displayed, or simply return nil for that row and/or column to not be searched
Discussion
Implement this method if you want to control the string that is used for type selection. You may want to change what is searched for based on what is displayed, or simply return nil to specify that the given row and/or column should not be searched. By default, all cells with text in them are searched.
The default value when this delegate method is not implemented is:
[[outlineView preparedCellAtColumn:tableColumn row:[outlineView rowForItem:item]] stringValue]and you can return this value from the delegate method if you wish.
