I dunno, that sounds like even more work than setting the frame size to
{0, 0}.
If there really isn't a "setVisible:NO" or something like that for
NSControls, then I guess I will keep doing things with the frame size.
Kind of a bummer, but it's already coded up, so no big problem for me.

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.
