Re: Q: GtkTree - how to get parent and grandparent text?

[Aaron Trevena <betty termisoc org>]

tree-owner is your friend - see the GTK tutorial, and for additional
identification use the arbitary data add and read functions also in the
tutorial somewhere.

see example below of a function called by the select child signal:

static void cb_select_child (GtkWidget *root_tree, GtkWidget *child,
                             GtkWidget *subtree)
{
  gchar *name, *parent_name;
  GtkLabel *label;
  GtkWidget *parent;

  g_print ("select_child called for root tree %p, subtree %p, child %p\n",
           root_tree, subtree, child);

  label = GTK_LABEL (GTK_BIN (child)->child);
  gtk_label_get (label, &name);
  g_print ("\t%s selected \n", name);

  if (GTK_TREE (child->parent)->level == 2)
    {

       parent = GTK_TREE (root_tree)->tree_owner;
       gtk_label_get (GTK_LABEL (GTK_BIN (parent)->child), &parent_name);

       g_print ("\t-- %s is parent of %s \n", parent_name, name);

     }
}

Maybe the getting parent details and snarfing arbitary data should be in
the faq - I don't think I saw them there.

Gosh C is a bitch after hacking perl for so long (perl is my bitch!)
