Okay, when one drags a control onto a window, selects the "assistant pane" button (so both IB and the header file are on screen at the same time), then right-click-drags the control onto the header file (under the @interface... line, of course), it lets you create an outlet (or action), and it shows up as "connected" (i.e. there's a little filled-in circle in the gutter, in both the header and implementation - for an action, anyway.)
But how does this work? A header file is just a plain text file with a ".h" extension, how can any outlets actually connect to it? Is it storing it in file metadata? Just curious.
