What's the easiest way to hide an NSControl?
The usual answer is to remove it from its superview. However, you
should seriously consider whether you should be hiding a control in
the first place... users often find user-interface elements that
vanish confusing; especially if it isn't obvious how to get them back
again. (I had an experience exactly like this the other day with
Apple's Shark tool... I lost the PPC970 instruction group display ;-)
[found it again now, though].)
If I remove it from the superview, how do I bring it back? Will
addSubview: put it back in the right place?
FWIW, this won't affect end-user experience. All the control showing
and hiding will happen before the NSWindow ever appears. It's a block
of checkboxes, and sometimes we need four of them, and sometimes we
need fewer.
