In Finder, when I use the List view mode, dropping an item on the header makes it a child of the currently-viewed folder. In that case, you don't want to do anything with the header, you just want to interpret "not dropped on any node" as "make this a root node", right? So, if Folder A has a child Folder B, and Folder B has a child Folder C, and the Finder is opened to Folder A's contents, dragging Folder C and holding it over the header, which means the drop will have "no target node"), you want Folder C to become a child of Folder A, and sibling of Folder B, right? If this is the case, then in your -outlineView:acceptDrop:item:childIndex: method, you'll want to respond accordingly if "item" is nil. If it's nil, it needs to be a root item. -- I.S. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
