18 *
19 * The sound can be played doing something like this:
20 *
21 * \code
22 * KTempFile tmp;
23 * if ( sound.isIntern() ) {
24 * tmp.file()->write( sound.data() );
25 * tmp.close();
26 * KAudioPlayer::play( tmp.name() );
27 * } else if( !sound.url().isEmpty() ) {
28 * QString tmpFile;
29 * if ( !KIO::NetAccess::download( QUrl( themeURL.url() ), tmpFile, 0 ) ) {
30 * KMessageBox::error( 0,
31 * KIO::NetAccess::lastErrorString(),
32 * i18n( "Failed to download sound file" ),
33 * KMessageBox::Notify
34 * );
35 * return;
36 * }
37 * KAudioPlayer::play( tmpFile );
38 * }
39 * \endcode
40 *
41 * Unfortunately, KAudioPlayer::play is ASync, so to delete the temporary file
42 * the best you can really do is set a timer.
