Thanks for the suggestion, but I need to be able to set the contents of the
cell (e.g., the labels of the different buttons) before the selected
index/tag/label is of any use.
With a data source, the cell received a 'setObjectValue' call with an array
of items, each corresponding to a different button, so it was easy to
iterate over said array and assign the buttons in one quick gesture.
With bindings, every other type of cell (?) has a 'value' binding which
corresponds to the same setObjectValue method, which is called automatically
when the data is populated into my underlying array. But NSSegmentedCell
lacks it completely - perhaps I have to subclass it and add my own bindings?
I haven't done that before, but I guess I'll give it a shot.
If anyone has had any experience with the NSSegmentedCell in a bindings
fashion, please let me know what steps you took to get it working.
Thanks!
Regards,
Mike
