Re: [gtk-list] Perl/Gtk CVS 19991001 CList->get_row_data

[CountZero <countzero cyberdeck org>]

Looking at the Gtk Reference at www.gtk.org, I notice no gtk_ctree_set_row_data()
I do see a gtk_ctree_node_set_row_data(ctree, node, data)
same with the get_row_data() calls...  I see no reference to either of these in the
Gtk::Perl reference at http://www.lettere.unipd.it/~lupus/perl-gtk-ref.html

Also, remember all row_data() is stored as a reference... so you must de-reference
it to get your actual data...

Personally, I just use a hash to store node data for a CTree... ie:

$node = $ctree->insert_node(blah blah blah);
$data{$node} = "my data";

then to retrieve (Say for a selected node):

foreach $node ($ctree->selection()) {
	print ("$data($node)\n");
}

I have found that public hashes shared by the subroutines in my program are much easier to
deal with.  I do use the CList->set_row_data etc, because CList rows don't exist as unique
widgets in and of themselves.  CTreeNodes do...
