How would you get a return value from a Button event when the event calls a subroutine. Below is the code for my button: 
my $mw = MainWindow->new;
$mw->title("Something");
my $but_browse = $frm_name -> Button(-text=>"BROWSE",    
   -command =>\&load_listbox) -> pack(-side => 'left');

sub load_listbox {
    my $filepath = $mw->chooseDirectory() or return();
    
        opendir (DIR, $filepath) || die("Cannot open
            directory");
    $lb->delete(0, 'end');
    $lb->insert('end', grep { ! -d } readdir DIR);
        close DIR;

    $lb->bind('<Button-1>', 
          sub { $ent4->configure(-text => 
                             $lb->get($lb->curselection( )) );
                $ent5->focus;
              });

}

When this button is clicked, I am able to choose a directory. I store the path in $filepath, how to do I access that variable to get the path? I have another button that needs the filepath from this button? Do I need "return $filepath;" at the end of the load_listbox sub? Whats the code I would need to access it? Would it be something like "$thepath = $but_browse=>get();". Thanks in advance!
