qt - Get meta data from delegated files using QML -

-

i'm creating music player ubuntu touch in qml , have things appreciate since i'm new qml.

i have list of tracks directory, want show meta data (artist, track name, year, album , on) instead of filename.

using qt.multimedia able meta data playing track, can't find how per file folderlistmodel delegated files.

how that?

this current code:

            column {                 anchors.centerin: parent                 anchors.fill: parent                 listview {                     id: musicfolder                     folderlistmodel {                         id: foldermodel                         folder: musicdir                         showdirs: false                         namefilters: ["*.ogg","*.mp3","*.oga","*.wav"]                     }                     width: parent.width                     height: parent.height                     model: foldermodel                     delegate: listitem.subtitled {                         text: filename                         subtext: "artist: "                         onclicked: {                             console.debug('debug: user pressed '+musicdir+filename)                             playmusic.source = musicdir+filename                             playmusic.play()                             trackinfo.text = playmusic.metadata.albumartist+" - "+playmusic.metadata.title // show track meta data                         }                     }                 }             }

it seems easiest thing here go c++ library can parse meta data out of these files , use create custom listmodel in c++ populates information onto itself. unfortunately, have done in c++ javascript not have io capabilities read , parse files.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
