/** A toplevel to use as drag icon.
 *
 * %Gtk::DragIcon is a Gtk::Root implementation with the sole purpose
 * to serve as a drag icon during DND operations. A drag icon moves
 * with the pointer during a drag operation and is destroyed when
 * the drag ends.
 *
 * To set up a drag icon and associate it with an ongoing drag operation,
 * use get_for_drag() to get the icon for a drag. You can
 * then use it like any other widget and use set_child() to
 * set whatever widget should be used for the drag icon.
 *
 * Keep in mind that drag icons do not allow user input.
