Thanks for the reply Martin, but I do have the slider & textfield hooked up
through an outlet/action. This part works ok, i.e. I am able to have the
textfield updated from the slider. It's just that even though the
textfield has it's value updated from the slider, this value isn't sent to
the textfield's delegate (my controller object in this case) unless I go in
and manually hit return in the textfield or manually edit the text. Only
then does the controller object get the update through delegation.

Correct me if I understood you wrong:
You want to update the NSTextField every time the NSSlider Value is
changed?
Nothing simpler than that, for now you have implemented the NSSlider as
an Outlet, right?
You just have to implement it as an Action too, just like a Button. This
action method will then be called every time you change the Slider.
Hope that helps!
Regards,
Martin
