I'm not quite sure what you are trying to do ... 

If a container doesn't display any border decorations (hbox, table, ...)
then there isn't a difference.

All containers that display border decorations only take one child
(button, frame). 
  
   * If the child is a container, call gtk_container_border_width on
   that child.

   * If the child is a misc widget (label, pixmap, arrow), then call
   gtk_misc_set_padding(misc, xpad, ypad). For a button created with 
   gtk_button_new_with_label, it is probablt acceptable to do

     gtk_misc_set_padding(GTK_MISC(GTK_BIN(button)->child), xpad, ypad);

   though it might be cleaner to do it in one step.

   * If the child is something else (preview...), then you'll have to
   put it inside an auxilliary container (e.g., a box) and call 
   container_border_width on the auxilliary container.

Hope this helps,
                                        Owen
