I'm trying to implement drag & drop in my NSCollectionView, following the 10.6 release notes. I've got my delegate set, but nothing was happening. I then implemented each of the methods to see if any were called, and none are. I've verified that the delegate is indeed connected.
Not to discourage you, but my experience with NSCollectionView in 10.5 was that it was extremely buggy; in the end it probably cost me more time to try to get it working in my app, than it would have to just write my own equivalent. But hopefully this is better in 10.6, so don't give up yet :)
What helped me out was to look for Apple sample code using NSCollectionView, and change it around to try to add the feature I was trying to make work. Sometimes that showed how a seemingly-innocent difference in my code or nib was actually preventing it from working, for some reason.
