Since then there has been a lot of confusion.


For those of you who don't know what drag-and-drop means:
  Try to ftp PMZIP, a very handy program which is a good demonstration
  of the drag-and-drop interface. (you can also get it from Blekul)


I use OS/2 1.3 with the 1.2 toolkit (IBM)
The drag-and-drop is undocumented in this toolkit.

But PMZIP works on 1.2, so 1.2 can support it.

* MY QUESTION:
* Can someone post a little sample program (with source of course) which
* demonstrates how to program the drag-and-drop ???

It is so usefull, and would make programs a lot fancier.

Think of this: A PM file Browser which support drag-and-drop:
  You select a file in the FileManager, and drag it to the Browser icon...
  That would be GREAT !!! (I always want to view a file when I'm working
  with FileManager, and have to exit it first and reselect the file using
  the PM Browser list-box.... :-) )

Thanks !
