Drag and drop

As a newcomer to LispWorks I'd be grateful for advice on implementing a
feature in the CAPI UI on the Macintosh.

I am trying to port an application to LispWorks that makes extensive use of
drag and drop to copy objects between sets. For example, I want to define
two list panels that allow you to drag and drop items between the lists, a
bit like the standard example double-list-panels.lisp but using
drag-and-drop.

Has anyone implemented this? If not, is it something that could be done by
writing interfaces to Cocoa, or would it need low-level programming to
achieve it?

Many thanks,
David Johnson-Davies
