Perl gurus, Thanks in advance for your knowledge! I'm sure this is fairly simple, but I do not have the slightest idea how to get the output from the button click event. What I am trying to do is have the user choose a DIR, the button event will return the path of the directory. I will then assign the path to a variable and populate a listbox. See the code below, let me know if you would prefer the whole code:

my $but = $mw -> Button(-text=>"Find Directory", 
-command =>\&get_path) -> pack();

# This is what I used, but it is wrong  
# my($first) = $but;

# &LoadListBox($first);


sub get_path 
{
  my $filepath = $mw->chooseDirectory() or return();
  $ent -> delete(0, 'end');
  $ent -> insert(0,"$filepath");
  return($filepath);
}

sub LoadListBox($) {
    my $test = @_;  
    
    #$lb->delete('0.1', 'end');

    # Just use a plain old grep readdir pipeline to create a list of
    # filenames for our listbox.
    opendir (DIR, $test) || die("Cannot open directory");
    $lb->insert('end', grep { -f $_ && -r $_ } readdir DIR);
    close DIR;
}
