Cleaning a canvas

[Iñaki García Etxebarria <garetxe euskalnet net>]

Hi,

 Here goes an small question:
 How can I remove all the items in a GnomeCanvas?

 I have tried an:
 GList * ptr = canvas -> item_list;
 while (ptr != NULL)
{
 gtk_object_destroy(GTK_OBJECT(ptr -> data));
 ptr = ptr -> next;
}

And some minor variations but it doesn't work.

Any suggestion?
Greets, Iñaki
