Hi Experts,
Am trying to implement "drag and drop" for a NSCollectionView (similar to
icon view in Finder), although on starting the drag I get following
callbacks:
– collectionView:writeItemsAtIndexes:toPasteboard:
and
– collectionView:draggingImageForItemsAtIndexes:withEvent:offset:
*but none of the following callbacks on dropping:*
– collectionView:validateDrop:proposedIndex:dropOperation:
and
– collectionView:acceptDrop:index:dropOperation:
Any idea on what am missing here?
TIA,
Alex
