Re: pop menu with a right-click in a gtktreeview

gtk_menu_popup() consumes the menu widget (that is, calls destroy on it) for
itself.  Click in this window and watch when the lolcat complains on stdout:

Are you sure that's not just the last reference being lost for a local
variable?  A global like below seems ok.

I don't know enough glade to guess which way it happens there.
I thought glade created everything at startup, and then hung onto it
forever, if you know what I mean.

use strict;
use warnings;
use Gtk2 -init;

my $window = Gtk2::Window->new;
$window->add_events (['button-press-mask', 'button-release-mask']);
$window->signal_connect (button_release_event => \&do_menu);
$window->signal_connect (destroy => sub { Gtk2->main_quit });

my $menu;

sub do_menu {
    my ($widget, $event) = @_;

    $menu ||= do {
      my $menu = Gtk2::Menu->new;
      $menu->signal_connect (destroy => sub {
                               print "halp, i'z bein destroyeded!\n";
                               return 0;
      my $item = Gtk2::MenuItem->new ("Cheezburger");
      $menu->append ($item);

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

    return 0;

Blessed are the cheesemakers
