If you implement the method:
- (void)tableView:(NSTableView *)aTableView setObjectValue:anObject
forTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex
in your datasource it will be called when the checkbox changes state -
<anObject> will be the value of the checkbox as an NSNumber and
<aTableColumn>'s identifier will tell you which column it was part of,
and the rowIndex tells you the row.

S.O.S.

I have an NSTableView with several columns of checkboxes. Each of my
columns has an identifier. I also have an NSObjectController
subclass acting as both data source and delegate. I can populate the
table with some data.
However I am stuck on how to know when a checkbox has been clicked
on so I can update my model. I would prefer to get the info as a row
number in a particular column if that is possible.
I actually created an 'update' method in my controller and linked a
checkbox to this and can receive the message when a checkbox is
clicked but the sender doesn't have any obvious column/row info so
I'm pretty sure this isn't the way to go. Also I don't want to use
bindings as the data is C++;
- (void)update:(id) sender{
}
Any help greatly appreciated,
thanks
