        id: virtualkeyboard
        width: 0.95*parent.width
        anchors.bottom: parent.bottom
    }
}

You can create a class Mykeyfilter, it's a QObject class

then in your file .h you declare:

bool eventFilter(QObject *object, QEvent *event);

Then in your Mykeyfilter.cpp file you define eventFilter like this:

bool MykeyFilter::eventFilter(QObject *object, QEvent *event)
{
    switch(event->type())
    {
    case QEvent::KeyPress:
    case QEvent::KeyRelease:
        {
         //////call your sound class here that you want to play/////
         qDebug()<<"I have clicked"  //For testing
        }
    default:
        break;

        //         return QObject::eventFilter(object, event);
    }

    return QObject::eventFilter(object, event);

}

Also add in your main.cpp file:

#include "mytouchfilter.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QQmlApplicationEngine engine;

    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    app.installEventFilter(new MykeyFilter());

    return app.exec();
}
