I think I stated that correctly. Is it possible? If so a pointer
to the appropriate doc would be appreciated.
Looking through the doc it seems that an image will retain its
path with -setDataRetained if initialized using –
initByReferencingFile:
but even then I see no way to get the path.
That's right - you can't. Once data is in the form of an NSImage its
original path isn't available, regardless of whether the image retains
the data or not. It's probably in there somewhere but there's no
public API (please file a bug requesting one, it would help me also!).
You need to go back a step and intercept the drag at an earlier stage
when it's still just a filename or file promise (whatever the Finder
sends, I can't remember).
