示例1: idFromPlaylistItem

{
QVariantMap metaData;
// The track ID is annoying since it must result in a valid DBus object
// path, and the regex for that is, and I quote: [a-zA-Z0-9_]*, along with
// the normal / delimiters for paths.
PlaylistItem *item = Playlist::playingItem();
if (!item)
return metaData;
FileHandle playingFile = item->file();
QByteArray playingTrackFileId = idFromPlaylistItem(item);
metaData["mpris:trackid"] =
QVariant::fromValue<QDBusObjectPath>(
