Saying -setAllowedFileTypes: to an NSOpenPanel while the panel is showing
causes no change in what's selectable. Evidently you're supposed to specify
the allowed file types when you start running the panel. Thus it appears
that -setAllowedFileTypes: is useless, which is weird, because in that case,
why does it exist? That, at least, is the conclusion reached during a
discussion of this issue at a different venue (a newsgroup). I myself am
just confused and would like to know how this is supposed to work. I would
think that being able to change the allowed file types while the panel is
open would be useful. m.
