The cursor when dragging from a clist

[Salvatore Valente <svalente dimins com>]

I have a program that allows you to drag items from a clist to a
drawing area.  While dragging, the cursor with becomes an arrow with a
little document (a sheet of paper with a folded corner) under the
arrow.  A document is not a particularly good representation of what's
being dragged in this case.  How can I make the document picture go
away?  (I'd like the dragging cursor to be just an arrow.)

I thought that gtk_clist_set_use_drag_icons(FALSE) would make
the document go away, but it didn't seem to have any effect.

Alternatively, how can I change the document picture to some other
picture?

Thanks,
