Re: [MacPerl] Using Mac:: '...' Modules

["Quentin Smith" <macmania@bit-net.com>]

Not to say your solution isn't good, but here is a version that does not use
a filterproc, and therefore is faster:

#!perl
#
# ChooseFiles - Choose (text) files
#

use Mac::Navigation;

$options = NavGetDefaultDialogOptions();
$options->dialogOptionFlags(
  $options->dialogOptionFlags | kNavNoTypePopup);
$options->message("WH3R3 R 7H3 F1L3Z?");

$types = new NavTypeListHandle "McPL", ["TEXT"];

$reply   = NavGetFile("", $options, $types, undef, undef, undef) or die $^E;

for ($i = 0; $i++<$reply->count; ) {
   print $reply->file($i), "\n";
}
__END__
