Tk Drag & Drop: tkdnd is an extension that adds native drag & drop capabilities to the tk toolkit. It can be used with any tk version equal or greater to 8.4 and currently only the UNIX (X-Windows) and Microsoft Windows operating systems are supported. Under unix the drag & drop protocol in use is the XDND protocol version 4 (also used by the QT toolkit, KDE & GNOME Desktops). Under Windows, the OLE drag & drop interfaces are used.

tkdnd can be found at SourceForge.
