Network

Downloader

Also aliased as 'StringDownloader' since Amarok 2.1.

 function somefunction(reply){ //do something with the reply, returned as a String }
 new Downloader( "url", somefunction, "encoding" );

The encoding argument is optional, it defaults to utf8.

DataDownloader

Since Amarok 2.1

DataDownloader works essentially just like StringDownloader except the result is a QByteArray instead of a String. The QByteArray requires that Importer.loadQtBinding("qt.core") to be run prior to using it. DataDownloader should be used for fetching files such as images.

 function showImage(reply){ 
     pix = new QPixmap();
     pix.loadFromData( reply );
     label = new QLabel();
     label.pixmap = pix;
     label.show();
 }
 new DataDownloader( "", showImage );

Examples

CurrentTrack

 Amarok.alert(Amarok.Engine.currentTrack().artist)
 Amarok.alert(Amarok.Engine.currentTrack().title)

Timer

A timer event will occur every interval milliseconds until killTimer() is called. If interval is 0, then the timer event occurs once every time there are no more window system events to process.

function timedAlert(interval) {
   var qo = new QObject();    
   qo.event = function(qevent) {           
     Amarok.alert("Timer triggered!");
     this.killTimer(qo.timerID);
   }
   qo.timerID = qo.startTimer(interval);
}

• int interval
