>Description</H2
><P
>GTK+ has a rich set of functions for doing inter-process
communication via the drag-and-drop metaphore. GTK+
can do drag and drop (DND) via multiple protocols.
The currently supported protocols are the Xdnd and
Motif protocols.
As well as the functions listed here, applications
may need to use some facilities provided for
<A
HREF="gtk-selections.html"
>Selections</A
>.
Also, the Drag and Drop API makes use of signals
in the <A
HREF="gtkwidget.html"
>GtkWidget</A
> class.</P
