you can add multiple rules to a filter, but in this case I'd check the
OS you're running on to decide what to use, e.g.:
if ($^O eq 'MSWin32') {
$filter->add_pattern('*.mp3');
}
else {
$filter->add_mime_type('audio/mp3');
}
or, since add_mime_type() is ignored on Windows:
# default to MIME type...
$filter->add_mime_type('audio/mp3');
# ... and add the extension matching on Windows
$filter->add_pattern('*.mp3') if $^O eq 'MSWin32';

not always; gtk+ will try (through GLib) to do the things in a portable
way but different features on respective systems have to be accounted
for by the application developer.
ciao,
