示例1: idFromPlaylistItem
QVariantMap MediaPlayer2Player::Metadata() const
{
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>(
QDBusObjectPath(playingTrackFileId.constData()));
metaData["xesam:album"] = playingFile.tag()->album();
metaData["xesam:title"] = playingFile.tag()->title();
metaData["xesam:artist"] = QStringList(playingFile.tag()->artist());
