INF: Windows Version 3.00 Drag and Drop Protocol ID Number: Q65819

3.00 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.
