Well I do have the checkbox bound to the controller. It is bound to
one of the attributes in the array of mutable dictionaries contained
within my NSArrayController.
But I don't see how this lets me get control to do something when
someone clicks the checkbox.
Two possibilities:
* If you used a custom class rather than a dictionary, then there
would be a setter of your own design called when the property is set
due to a change in the checkbox. You could put code into that setter
to do... whatever.
* Your controller can use KVO to observe the property to which the
checkbox is bound. Then it will receive change notifications when the
property is changed.
Yes I can put an action on the ButtonCell, but this doesn't tell me
which record in the array the clicked cell relates to.
If you use bindings to set the target of the cell, and you use a
custom class with an action method rather than a dictionary, you could
have the cell deliver an action directly to the model object.
