Thanks, that worked fine.

One more question (I haven't got the sources for the GnomeCanvas),
What does item_list store (Ok, the list of items, it sounds stupid), and
more important, how?
ie: How can I gather information about the items in a Canvas through
this structure?
Is ptr -> data a (GnomeCanvasItem *)?
