Okay, this works.

According to the fine reference documentation $node->row->parent
should return a node and you can poke inside that.

I don't mean to be a pain in the neck , I'm poking through all the
documentation i can find, along with the .pm and .xs files from the
distribution.  But sometimes, even when I find the answer I don´t
recognize it.  :-) Perhaps you could tell me where you found this
particular gem?

I don't see anything renamed to titles there: a node contains the
text of all the columns (if they are text columns, that is).

The Gtk API refers to this field as "text" , in  insert_node_defaults
(undocumented as far as I can tell) you call it "titles".  Not a big

get_node_info() returns all the info you could set on the cell:
($text, $spacing,  $pixmap_closed, $mask_closed, $pixmap_opened,
        $mask_opened, $is_leaf, $expanded) = $ctree->get_node_info ($node);

In scalar context you just get the text.

Not true.  In scalar mode you get a count of the number of defined
values returned.  To get just the text you can do

($text) = $ctree->get_node_info ($node);

which is still array mode.

set_row_data/get_row_data can be used in a Gtk::CList that is a parent
class for Gtk::CTree, but should not be used in a Gtk::CTree.
I should probably add a sub Gtk::CTree::set_row_data {die} to
prevent people from using it....

Or you could overload the xs for node_set_row_data / node_get_row_data
so that they do what you might expect them to do.

Lupus (Gtk-Perl maintainer) suggested 5 Dec 1999:
gtk_ctree_node_get_text() works only when the node is a text node.
You should use gtk_ctree_node_get_pixtext() if it's a pixtext one,
and so on.
Anyway, I added gtk_ctree_get_node_info() to the bindings.

So does insert_node or default_insert_node always give you a pixtext
node?  How do you get a text node or even distinguish between pixtext
and text nodes?  Are there also other types of nodes?

Thank you very much for your patience, I think you have a great tool,
can I help make it better?
