Either make your own cell class, or use two columns for that. I’d
recommend the latter due to simplicity, but it may not give you the
look you’re going for.

Great! Thanks for the info. I hoped it was something simple.

Go with Objective-C: it’s the native language for Cocoa, so there’s no
impedance mismatch. Plus, you can leverage your C/C++ knowledge where
you want/need to more easily than you could in Ruby or Python. (C# is
an unknown quantity for me, so I can’t really comment on that.)
Plus, if you’re
OpenGL has a steep learning curve, but it’s the only truly 3D
framework out of all of these mentioned. Quartz is 2D-only, and only
wraps OpenGL as a matter of performance and/or convenience;

I’m interested to know if there’s a better way to do this than the
ugly way I’ve been using, too:
NSString *first = [string substringWithRange: NSMakeRange(0, 1)];
NSString *rest = [string substringFromIndex: 1];
NSString *result = [[first uppercaseString] stringByAppendingString:
rest];
See -sortUsingFunction:context: in NSMutableArray’s documentation. As
Ricky Sharp has already mentioned, there’s also -sortUsingSelector:,
however if you’re comparing partly with external data you might like
having the void * context provided by this method.

I'm using a master/detail view in my application. If the user
select another row in the master table and the detail has been
modified, I want to present an alert to save, cancel or return to
detail.
Just my 2¢ worth, but this sounds like a horrible UI. If I get
interrupted by an alert
Do the simplest thing that could possibly work. In some cases, like if
you need to be calling -performSelector:withObject: with each of these
things, that might be the NSArray. In your case, it sounds to me like
it’s the C array of floats.
Just my two cents.

It sounds like you’re looking for [aboutPanel makeKeyAndOrderFront:
self];.
