GnomeCanvasGroup's children?

[sottek <sottek quiknet com>]

Could someone please tell me how to get the children of a
GnomeCanvasGroup
without casting it to _GnomeCanvasGroup? Seems like there probably
should
be a way to do something like:
    children = (GList *)gtk_object_get_data(GTK_OBJECT(canvas_group),
						    "item_list");

however this doesn't seem to work and the documentation....err header
says:

/* GnomeCanvasGroup - a group of canvas items
 *
 * A group is a node in the hierarchical tree of groups/items inside a
canvas.
 * Groups serve to give a logical structure to the items.
 *
 * Consider a circuit editor application that uses the canvas for its
schematic
 * display.  Hierarchically, there would be canvas groups that contain
all the
 * components needed for an "adder", for example -- this includes some
logic
 * gates as well as wires.  You can move stuff around in a convenient
way by
 * doing a gnome_canvas_item_move() of the hierarchical groups -- to
move an
 * adder, simply move the group that represents the adder.
 *
 * The following arguments are available:
 *
 * name         type            read/write      description
 *
--------------------------------------------------------------------------------
 * x            double          RW              X coordinate of group's
origin
 * y            double          RW              Y coordinate of group's
origin
 */

which seems to imply that only the x and y are available for
gtk_object_get_data();

BTW: on a larger note why is the information in the headers above not
included in the
online API reference?
