OK, now a scoping rule question, in the sample code below, does "self" refer to my object (i.e., the "self" when the block is declared) or the NSSavePanel (i.e., the "self" when the code is executed)?
Your object. Even though the save panel is calling that block, that has no effect on what 'self' is (just as in a normal method call.) Blocks keep track of the values of variables declared in the function/ method they're in, and keep those values when they're run; that's part of what makes them so powerful.
