    Thumbs up QtMultimedia error Sound Effect

    Well, my problem is the sound that did not come out because inside the call of the object "Qt.createQmlObject ()" I can not use the QtMultimedia 5.0 module with a "muted:" property that receives the value of!! ; " I get an error message

    file:///C:/Users/joaovictor/Desktop/demarsia/conteudo/EfeitoSonoro.qml:7: Error: Qt.createQmlObject(): failed to create object:
    file:///C:/Users/joaovictor/Desktop/demarsia/conteudo/inline:1:143: Cannot assign to non-existent property "muted"

    (the module .qml)
    O módulo EfeitoSonoro.qml:qterr.jpg

    Qt Code:
    1. import QtQuick 2.0
    2. import QtMultimedia 5.0
    3. //Proxies a SoundEffect if QtMultimedia is installed
    4. Item {
    5. id: container
    7. property QtObject effect: Qt.createQmlObject('import QtMultimedia 5.0; EfeitoSonoro{ source: " ' + container.source + ' "; muted: ! } ', container);
    8. property url source: ""
    9. onSourceChanged: if (effect != null) effect.source = source;
    10. function play() {
    11. if (effect != null)
    13. }
    14. }

    Default Re: QtMultimedia error Sound Effect

    Your EfeitoSonoro element doesn't seem to have a "muted" property.

    Also, are you sure you want to create an object of its own type inside the object?

    Cool Re: QtMultimedia error Sound Effect

    Thanks !! I'm a newbie but now I understand that the call of a object is other QML object and not my created qml. now works perfectly

    the SoundEffect{} is the correct call very thanks dude!
