GtkTreeView DND

[Paul Pogonyshev <pogonyshev gmx net>]

I installed a callback to a GtkTreeModel's (GtkListStore)
`row-inserted' signal.  It gets called and tree path and
iterator both seem fine, but I cannot get values from
the inserted row---it just returns NULL's.


static void
handle_drag_and_drop(GtkTreeModel *tree_model,
                     GtkTreePath *tree_path, GtkTreeIter *iterator)
{
  MyDataFormat *data;

  gtk_tree_model_get(tree_model, iterator,
                     MY_DATA_COLUMN, &data, -1);

  /* FAILS */
  assert(data);
}


Everywhere else gtk_tree_model_get() works just fine and
the data is never NULL.  Any ideas?  I tried to connect
with both g_signal_connect() and g_signal_connect_after().
