I'm having trouble getting drag and drop to work with an NSOutlineView. What I've done is below. The problem is that "tableView:writeRowsWithIndexes:toPasteboard" never gets called. I found a few people with the same issue and it seems that the cause of the problem is that I am using a custom cell that is a subclass of NSTextFieldCell, however I haven't been able to find a solution that fixes my problem.
1. Set the NSOutlineView's delegate and datasource outlets. 2. In the datasource's awakeFromNib method I call "registerForDraggedTypes:" on the outline view. 3. I implemented the following methods in my datasource: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteBoard *)pboard - (BOOL)outlineView:(NSOutlineView *)outlineView acceptDrop:(id < NSDraggingInfo >)info item:(id)item - (NSDragOperation)outlineView:(NSOutlineView *)outlineView validateDrop:(id < NSDraggingInfo >)info proposedItem:(id)item proposedChildIndex:(NSInteger)index Any help is greatly appreciated! _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
