The code you are looking to is intended as an example of how to prepare a Mac

Thank you all for pointing me to the solution of my question.
My first thought was that you could change the target of the menu item
so that it calls your own method, then call the original
showHelp method with something like:
[NSApp showHelp:sender]
This is what I did now, using an own -my
In my app's main window, I have a button which should kill a process
from the running system processes. (Guess what - it is helpd.)
In -awakeFromNib:, a private app delegate method -checkHelpd: checks if
some other app has already launched helpd. If so, the button will be
drawn as enabled, els
Your Button has to draw itself after it called its action.
You try to change state while you are still in the action.
Did you try to performSelector after 0.0?

Jens, Quincey,
Thank you for all the valuable info. My image dpi is indeed higher than 72.
Combining your info, I elected to use, for now:
NSImage* tempImage = [NSImage imageNamed: @"image1"];
NSImageRep *rep = [tempImage bestRepresentationForDevice: nil];
int width = (int)rep.pixelsWide;
I have a runloop running in an NSThread. In this thread is a timer which fires
every 2 seconds. In the timer, I check [NSThread isCancelled] and if so, stop
the runloop via CFRunLoopStop.
The runloop is run via runUntilDate:distantFuture.
Shouldn't runUntilDate terminate once CFRunLoopStop has
Hi Matt.
Is there a reason that you're using -[NSRunLoop runUntilDate:] instead of
CFRunLoopRun()?
According to the documentation, runUntilDate: "runs the receiver in the
NSDefaultRunLoopMode by repeatedly invoking runMode:beforeDate: until the
specified expiration date." So even if CFRunLoopS

Not really, and it was a bit daft to use NSRunLoop to start it off and then
CFRunLoop to stop it.
Anyway, your solution worked perfectly.
Thanks

It’s OK to call -setEnabled: during a button action method. I’ve done it a lot.

Not quite a cocoa question
By chance, does somewhere know where the images are for the eject button in
finder. I looked in /system/library/coreservices/finder and they are not
bundled with it. I'd prefer the Mac OS X versions and not some 3rd party.
Thanks in advance.

That's not the Finder sidebar icon, though. I'm not sure I've seen anything use
that one.
Also I think Apple frowns on copying their icons into your apps. Only the ones
you can get through imageNamed: or iconForFileType: are fair game.

The purpose of the program is to compare the visibility of the text when it is
static versus when it flickers (so in some ways it's similar to signage).
Therefore, I must make the text display switch back and forth between two
displays with opposite black/white contrast to produce the flicker -
Lee Ann and Patrick, thank you!
I suspect the one from ../coreservices/menu extras/Eject.menu uses the
character set one as well. They converted to a pdf for displaying as an
image. Again, thank you.

"Does not matter" is the answer. You can retain & release them all you want,
they're not going anywhere.
