Drag-n-Drop NSTabViewItem

Question

In my application, we have NSTabViewItem inside NSTab , and there could be More then one NSTabViewItem are possible,
To Support one of the feature, we need to support Drag-n-Drop in NSTabViewItem, i.e. i should be able to rearrange NSTabViewItem and if its dropped else where another control of our application, then some particular action should happen,

I went through documentation but didn't find any support for it, but it seems to be quite obvious use - case ,

Am i missing something

Answer 1

To be honest I never saw such a behaviour. I would give you the advice to use an NSTabView without tabs and to use AMButtonBar for example in order to select a tabviewitem with selectTabViewItemAtIndex: programmatically. You could adopt NSDraggingSource and NSDraggingDestination protocols then within this code to make the elements (of the button bar and not the table view itself) rearrangeable.
