The thing is, I've done all that and no drags are initiated when I drag on the
items. I have this in my tableview delegate:
But tableView:writeRowsWithIndexes:toPasteboard: is never even called. It seems
to me that the examples have this code in the datasource or something rather
than the delegate, but like I said, what do you do if you don't use a
datasource.
- (void)awakeFromNib {
[tableView setDraggingSourceOperationMask:NSDragOperationEvery forLocal:YES];
[tableView setDraggingSourceOperationMask:NSDragOperationEvery forLocal:NO];
[tableView registerForDraggedTypes:[NSArray
arrayWithObject:NSStringPboardType]];
}
- (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet
*)rowIndexes toPasteboard:(NSPasteboard *)pasteboard {
[pasteboard declareTypes:[NSArray arrayWithObject:NSStringPboardType]
owner:self];
[pasteboard setString:@"test string" forType:NSStringPboardType];
return YES;
}
