Okay, first attach a signal handler for "button_press_event"
and use gtk_signal_connect_after() for your GtkCList.

Then in your callback handler, use:

gint ButtonPressEventCB(
        GtkWidget *widget, GdkEventButton *button, gpointer data
)
{
            gint row, column;
            gint etype;
            gint rows_selected = 0, selected_row = -1;
            GList *glist;
            GtkCList *clist = GTK_CLIST(widget);


            etype = button->type;

            /* Find row and column based on given coordinates. */
            if(!gtk_clist_get_selection_info(
                clist, button->x, button->y, &row, &column
            ))
            {
                row = -1;
                column = 0;
            }

            /* Is it a double click? */
            if(etype == GDK_2BUTTON_PRESS)
            {
                /* Do double click routine here. */



            }

            return(FALSE);
}
