You need to call this on the destination table view (modified for
your needs, of course):
[yourTableView registerForDraggedTypes:[NSArray
arrayWithObjects:NSFilenamesPboardType, nil]];

As always I preface with the fact that I'm just learning how to
program so please be gentle. I was looking at those good examples
on mmalc's Cocoa Bindings Examples and Hints page. In particular,
I'm trying to use drag and drop from one tableview to another
tableview (controlled by a different array controller of course).
I first tried to implement the three drag and drop methods...
- (BOOL)tableView:(NSTableView *)tv writeRows:(NSArray*)rows
toPasteboard:(NSPasteboard*)pboard;
- (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id
<NSDraggingInfo>)info proposedRow:(int)row proposedDropOperation:
(NSTableViewDropOperation)op;
- (BOOL)tableView:(NSTableView*)tv acceptDrop:(id <NSDraggingInfo>)
info row:(int)row dropOperation:(NSTableViewDropOperation)op;
...in both of my array controllers. But then I got a bit lost.
The drag part works but I can't seem to get the other tableview to
accept the drop. In mmalc's example (it's the "Bookmarks" one) he
has what he calls a utility method...
-(void)moveObjectsInArrangedObjectsFromIndexes:(NSIndexSet *)indexSet
toIndex:(unsigned)index;
...and I wonder if that's my problem and that I need something like
this (but I just can't figure out what) for the "insert" role in
the new array.
If someone can suggest the right way to do it or point me to a
snipet of code that shows how to get drag and drop between two
tableviews.
Thanks
