使用MediaPlayer 来创建基本的实例。

 var player =
     MediaPlayer {
       repeatCount:MediaPlayer.REPEAT_FOREVER
       onError: function(e:MediaError) {
                  display = e.message;
                }
     };

控制 MediaPlayer类：

Button {
   enabled : bind enabled
   text: bind text
   action: function() {
              if (text == "Stop") {
                 player.pause();
                 text = "Play"
              } else if (player.media != null and text == "Play") {
                 player.play();
                 text = "Stop";
              }
           }
}

加载播放文件：

var fileBtn: Button
component:
    fileBtn = Button {
                text: "File"
                action: function() {
                          var fc = new JFileChooser();
                          var mp3Filter = new ExtensionFileFilter();
                          mp3Filter.addExtension("mp3", "MP3");
                          fc.addChoosableFileFilter(mp3Filter);
                          var result = fc.showOpenDialog(fileBtn.getJButton());
                          if (result == JFileChooser.APPROVE_OPTION) {
                             var fFile = fc.getSelectedFile();
                             display = fFile.getName();
                             var file = fFile.toURL().toExternalForm();
                             file = file.replaceAll(" ","%20");
                             if (file != player.media.source) {
                                player.pause();
                                player.media = Media {source:file};
                                text = "Play";
                                enabled = true;
                             }
                           }
                         }
                                     
              }
