Hey everyone,
I'm working on some drag and drop stuff, and have reached an impasse.
Currently, I've got a basic master-detail view, where I can drag and
drop to rearrange the groups in the master outline view. What I'd now
like is to be able to drop items from the detail view onto one of the
group items to copy it into that group (just like dragging an email
into a new folder in Mail.app, or dragging a song into a playlist in
iTunes).
I tried adding the type of the dragged item (a simple
NSStringPboardType) to the outline view's regsiterForDraggedType's
array, but I'm still not entirely sure what all the various delegate
methods are doing. I managed to get it working for rearranging, but
I'm now looking for somewhere that has a clear explanation of what the
delegate methods are, when they're fired, why they're fired, and maybe
some sample code to go with it.
I've taken a look at the Drag and Drop outline view in the sample
code, and also the Drag and Drop guide in the docs, but I'm really
looking for something that could explain this step by step.
Any pointers?
Thanks!
Dave DeLong
