No, the conclusion is : That _is_ the easy and straight way to do it.
Subclassing is your power and friend, my friend. Once you understand
what those lines actually do, you should have a different point-of-view.
"Embrace the subclass, for they know what they are doing." :-)

Ok. Let me try this.So conclusion is there is no easy and straight way to do
it. Have to subclass NSView.

Yes Mike, you ask a very pertinent question.
First I'm looking for a source-time (not compile-time) monitor that

The best way to ensure your daemon or agent is always running is to
have it run via launchd.
Start by reading the launchd man page and the "Daemons and Agents"
tech note; these will give you an overview of how Mac OS X used
launchd to manage these types of on-demand and always-on services.

Well in that case I don't understand what you mean by "no users will
be using the system." Do you mean you intend for your application to
run normally but unattended? I interpreted what you said to mean you
were writing a background daemon of some form.

The problem I have with this GCC __attribute__(unused) thing is that
it does not result in an error if you actually end up using the
attribute (as I would expect it should). If it went that extra step I
would find it more useful than doing just (void)param..., but since it
doesn't, I guess

You're creating an NSImage and pretending it's an NSImageView which
it's not. You'll need to create a new NSImageView and then the
