The ReadMe.rtf file within Apple's DragNDropOutlineView says that it
calls
draggingSourceOperationMaskForLocal. However I cannot find the string
draggingSourceOperationMaskForLocal anywhere within the project! So
how is it doing what it's doing?
"MyOutlineView overrides the method
draggingSourceOperationMaskForLocal: to allow our drags initiated
from our outline view to have destinations outside of our
application." Only thing is, it doesn't. MyOutlineView does not
mention draggingSourceOperationMaskForLocal anywhere.
Doesn't that make it a bug in the documentation?
I look at the DragNDropOutlineView example code, and it seems to be
doing things in a totally different way than Aaron Hillegas's book,
Apple's documentation on drag and drop, are telling us to do.
It's a good demo that does just what I need. Only problem is that the
documentation only serves to confuse, which in some ways is worse
than no documentation.
