I have an NSTableView with several columns of checkboxes. Each of

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

You could try to get a ref to the table view by asking sender about
it's superview. Or you could just get the selected row from the
tableview itself. Presumably you have a reference to it. When the
button is clicked, the row it's in will be selected. Not sure, but I
think you can get the column info from the tableview as well.
HTH,
