I haven't done the exact code that you are looking for, but I might be able
to guide you in the right direction.

First of all, to perform operations on the desktop (which is against Apple's
user interface standards in the first place), you have to work in the desktop's
window manager port, which is the port you get if you call GetWMgrPort() the
first thing after initializing your Inside Mac managers.  I'm not sure, but
pretty sure that this port can then be used by DragGrayRgn() which is
documented in the Window Manager of Inside Macintosh.

I wish I had the exact code for you, but if you follow up on these two leads
then you may be able to figure out how to drag icons on the desktop.  If these
fail, then you may try using a separate window for each icon, and using
DragWindow to move them if they are pressed on.  I'm not sure, but it might be
that DragWindow will work for plainDBox windows to move them from their
content area (you might try it and get back to me, I'd be curious).

Good Luck.
