Valued confreres,

I'm looking for a way to provide extra information on entries in a Tk::BrowseEntry. I use -listcmd because in the application I'll be adding dynamically to the dropdown list. First try:

    my @choices = qw/1    2    3/;
    my @help    = qw/one  two  three/;

    my $top   = MainWindow->new ();
    my $tag   = $top->Balloon (-state => 'balloon');
    my $entry = $top->BrowseEntry (%BE_args);
       $entry->configure
           ( -listcmd => sub
                {
                my $lb = $entry->Subwidget ('slistbox')
                               ->Subwidget ('listbox' );
                $entry->configure (-choices => \@choices);
                $tag->attach ($lb, -balloonmsg => \@help);
                }
           );

No luck. I thought that this could be caused by the listbox not being visible yet when listcmd() fires, so I tried:

    my @choices = qw/1    2    3/;
    my @help    = qw/one  two  three/;

    my $top   = MainWindow->new ();
    my $tag   = $top->Balloon (-state => 'balloon');
    my $entry = $top->BrowseEntry (%BE_args);
       $entry->configure
           ( -listcmd => sub
                {
                $entry->configure (-choices => \@choices);
                }
           );

    my $lb = $entry->Subwidget ('slistbox')
                   ->Subwidget ('listbox' );

    $lb->bind ( '<Visibility>'
              , sub
                  { $tag->attach
                        ( $lb
                        , -balloonmsg => \@help
                        );
                  }
              );

Again no luck. I've tried using the 'slistbox' subwidget itself, without success either. And I've verified that the Visibility callback actually triggers.

Is this even possible? If so, how?
