WINDOWS
Summary:
Certain operations can be performed by direct manipulation of icons in
the Windows version 3.0 File Manager and Program Manager. One of the
actions that is allowed is the ability to move a program among Program
Manager groups by dragging its icon from one group and dropping it
into another group.
There are messages in Windows that are currently undocumented that
support this behavior. These messages form the "Drag and Drop
Protocol."
Development work is still progressing on this protocol, which will be
changing in a future version of Windows. Once the necessary work is
complete, this protocol will be thoroughly documented and application
developers will be encouraged to use it in their applications where
ever it is appropriate.
