Need to stop QML Audio from cpp code



  • Hi,
    I have a qml which has audio playing.I need to pause the audio from QAPPlication ie cpp code.

    QML CODE is as follows


    import Qt 4.7
    import QtMultimediaKit 1.1

    Text {
    text: "Click Me!";
    font.pointSize: 24;
    width: 150; height: 50;

     Audio {
         id: playMusic
         source: "music.wav"
     }
     MouseArea {
         id: playArea
         anchors.fill: parent
         onPressed:  { playMusic.play() }
     }
    

    }


    When i hide my qml app ,I need to pause the audio playing.
    This is straight forward pausing in qml file by using signals and slots
    I need to pause the audio from cpp code .

    Please post me



  • One more thing ,I should know the Media that is playing and I should pause the media like in cpp code

    if(any media Object playing)
    // pause the media

    Again one my qml comes to foreground and if press play ,Audio should resume from where it has stopped



  • Take a look at the documentation: "Using QML Bindings in C++ Applications.":http://qt-project.org/doc/qt-4.8/qtbinding.html In particular, the section Exchanging Data between QML and C++ may be of interest to you.

    However, it is discouraged to modify a QML scene directly from C++, because it creates an unnecessary tight coupling between the UI and code-behind. Better way is to expose a QObject "model" to QML. Your QML scene state can then be controlled using the your model object's Q_PROPERTIEs. See the section Embedding C++ Objects into QML Components in the same doc article on how to expose objects from C++ to QML.
