Does anybody know if it is possible to get an EventLoopRef from my NSApplication's run loop? Greg found something that does exactly what I need, but it requires that I specify the run loop "the Carbon way" as an EventLoopRef. I just don't know how to reference my application's run loop as a Carbon EventLoopRef.
