You must add this feature directly to the FileView control, by modifying its 
source code.

Or you can inherits FileView, try to find its child IconView / ListView (not 
too difficult, use FileView.Children[0]) , and use the Observer class to 
catch Drag & Drop events sent to them.

--8<-----------------------------------------------------------------
'CLASS MyFileView

INHERITS FileView

PRIVATE $hObserver AS Observer

PUBLIC SUB _new()

  $hObserver = NEW Observer(ME.Children[0]) AS "TheIconView"

END

PUBLIC SUB TheIconView_Drop()

  PRINT Drag.Data

END
--8<-----------------------------------------------------------------

You have more work if you want to now which icon was specifically hit by the 
drop. 

Note that at the moment, gb.gtk IconView cannot returns the needed (X,Y,W,H) 
coordinates of an icon. I didn't find how to do that in GTK+, whereas the API 
allows that for TreeView items.
