Gtk2 Treeview/Simplelist and set_tooltip_row()

[jettero]

I'm enjoying Gtk2 quite a bit. I'm very new to it, but I've written some semi-fancy things with ease and it's just fun.

I got kinda stumped on tool tips though. I seem to be able to get them working everywhere except Gtk2::SimpleLists (which are really Gtk2::TreeViews).

It seems like I found most of the related topics, but I can't seem to get it to work. I want to add a tooltip to some of the rows of my simplelist.

# This is mostly their SmipleList example.  They skipped warnings and 
+strict, 
# I only wrote the (non-working) tooltip stuff.

use Data::Dumper;
use Gtk2 '-init';
use Gtk2::SimpleList;

use constant TRUE  => 1;
use constant FALSE => 0;

$categories = Gtk2::SimpleList->new ('Categories' => 'text');
$categories->set_headers_visible(FALSE);
@{$categories->{data}} = qw/Meat Beer Pizza Pasta Soda Juice Rabbitfoo
+d/;

$categories->set_has_tooltip(TRUE); # NOTE: thought this might help (n
+ope)

$path = Gtk2::TreePath->new_from_indices(0);
$tip = new Gtk2::Tooltip;
$tip->set_text("tooltip test");
$categories->set_tooltip_row($tip, $path);

# NOTE: thought this might help, but I fail to see how it would
# $categories->signal_connect( 'query-tooltip' => sub {
#     warn Dumper({args=>\@_, useless=>{tip=>$tip, path=>$path}});
# });

$window = Gtk2::Window->new;
$window->set_title ('SimpleList examples');
$window->signal_connect (delete_event => sub {Gtk2->main_quit; TRUE});
$window->set_default_size (800,600);
$window->add($categories);
$window->show_all;

Gtk2->main;

The documentation for both the C and the .pm is a little light (doxygen?), but I think I might need to do something with the signal? I believe it's been possible to do this since gtk 2.12.0, but I'm clearly missing something. There's some example code in the t/GtkTreeView.t that calls set_tooltip_row(), but it seems to be an example of testing something rather than an example of putting a tooltip on a row.
