Well, that is a nice bit of code to have, but it doesn't really
address the issue. As I wrote in my original post, there are a number
of published methods for handing this in (for example) the NSDocument
subclass. What *I* want to do is handle it in my NSArrayController
subclass, for encapsulation purposes - I have a number of different
tables for which I want to enable this, and I'd like to keep the
functionality separate. I am looking into the suggestion of
subclassing NSArrayController's addObject: method, which seems likely
to work.
Also, the scrollRowToVisible call is superfluous, since the
editColumn:row:withEvent:select: method is documented to do the
scrolling for you already. And, I think the setSelectedObjects can be
replaced by a checkbox in IB, right? (Although perhaps under some
circumstances you would not like the added row to be selected?)

I'm trying to have my table immediately enable editing of added

I have a handy NSTableView category to do that:
- (void)makeEditableSelectedCellOfColumnIdentifier:(NSString*)
inColumnIdentifier
{
NSTableColumn* column = [self
tableColumnWithIdentifier:inColumnIdentifier];
if (column && ![column isHidden])
{
if ([self numberOfSelectedRows] == 1)
{
NSInteger columnIndex = [self
columnWithIdentifier:inColumnIdentifier];
NSInteger selectRowIndex = [self selectedRow];
if ((columnIndex != -1) && (selectRowIndex != -1))
{
[self editColumn:columnIndex row:selectRowIndex withEvent:nil
select:YES];
}
}
}
}
So in response to some "add" button in the UI, I have an action method
that does:
foo = [arrayController newObject]
[arrayController setSelectedObjects:[NSArray arrayWithObject:foo]]
[tableView scrollRowToVisible:[tableView selectedRow]];
[tableView makeEditableSelectedCellOfColumnIdentifier:@"bar"];
hth,
