Hi, i'm a little rusty, but I think you will have to either make a separate menu for each item, or dynamically load the menu items from a hash or something. Gtk2 is very good about cleaning up menus that are self contained in a sub.... so don't feel bad about using the menu once then letting it be discarded....here is a cheap fast example

what I would do if I had more time to play around, is to have a hash containing your values( or maybe pulled from a db)..... then as you build your menu, plug in the values you need. Another thing to try is $menu->destroy your menu after each use, so the old global dosn't get left laying around..... watch for memory gains too as you run alot of menu calls.

As you can see from the code, you can get the button the menu is being called from, from the callback arguments being passed in..... so that gives you your way of loading a custom menu for the button in question.

One last point, I didn't use a treeview for my example, but what might be happening, is that your menu is attached to the treeview itself, not the elements. Remember, labels( common in treeview), don't respond to events.... you may need event boxes for each label to signal_connect to.

#!/usr/bin/perl
use warnings;

use Gtk2 'init';

my $w = Gtk2::Window->new('toplevel');
$w->signal_connect(destroy => sub { Gtk2->main_quit() });
$w->set_border_width(12);
$w->show();

my $vbox = Gtk2::VBox->new( FALSE, 6 );
$w->add($vbox);

my $b = Gtk2::Button->new_from_stock('gtk-ok');
$vbox->pack_start( $b, FALSE, FALSE, 0 );
$b->signal_connect(clicked => sub { $w->destroy() });

my $b1 = Gtk2::Button->new_from_stock('gtk-cancel');
$vbox->pack_start( $b1, FALSE, FALSE, 0 );
$b1->signal_connect(clicked => sub {  });

$b->signal_connect(button_release_event => sub {
        my ($button, $event) = @_;

        return FALSE if $event->button != 3;

        my $item;
        my $menu = Gtk2::Menu->new();

        $item = Gtk2::MenuItem->new_with_mnemonic('Item _1');
        $menu->append($item);
        $item->show();

        $item = Gtk2::MenuItem->new_with_mnemonic('Item _2');
        $menu->append($item);
        $item->show();

        $item = Gtk2::SeparatorMenuItem->new();
        $menu->append($item);
        $item->show();
        
        $item = Gtk2::MenuItem->new_with_mnemonic('Item _3');
        $menu->append($item);
        $item->show();

        $menu->popup(undef, undef,
                     undef, undef,
                     $event->button,
                     $event->time);

        return TRUE;
    });


$b1->signal_connect(button_release_event => sub {
        my ($button, $event) = @_;

        return FALSE if $event->button != 3;

        my $item;
        my $menu = Gtk2::Menu->new();

        $item = Gtk2::MenuItem->new_with_mnemonic('Z_1');

        $item = Gtk2::SeparatorMenuItem->new();

        $item = Gtk2::MenuItem->new_with_mnemonic('Z_3');
        $menu->append($item);
        $item->show();

        $menu->popup(undef, undef,
                     undef, undef,
                     $event->button,
                     $event->time);

        return TRUE;
    });
