You can bind the selection of the popup to a variable and then observe
that variable via KVO. I did that on a single NSPopUpButton, you would
still need to get the affected row.

Hi,
We all know that we can detect when regular text in an
NSTableView finishes editing using the control notification
method controlTextDidEndEditing:.
My problem, however, is this: In one of the columns I have attached
an NSPopUpButtonCell. The pop up button has two predetermined
constant choices "Foo" and "Bar" (always these two fixed choices).
How can I detect it when these values are have been changed (after
having selected a menu item)? The problem is that abovementioned
notification method, controlTextDidEndEditing:, is not getting
called in this case.
How, then, can I do some stuff after an NSPopUpButtonCell has
changed a value? Is there any other notification method I can use? I
have not yet seen such a method in the docs.
Thanks, U.
