Incidentally, this document tells you all you need to know (and can

If you've exhausted all other options, you might try taking a

function the same as a transparent mouse-event-grabbing window, as you

If you know the selector at compile time, you should use @selector()

Otherwise you should use the sel_getName() function to do the lookup
