QML: Component.onDestruction not calling on window close

[nestuser]

My sample code is

QDeclarativeView* view = new QDeclarativeView();
    view->setSource(QUrl::fromLocalFile(filename));
    QWidget *widget = new QWidget();
    QVBoxLayout *layout = new QVBoxLayout(widget);
    layout->addWidget(view);
    widget->show();

QDeclarativeView* view = new QDeclarativeView();
    view->setSource(QUrl::fromLocalFile(filename));
    QWidget *widget = new QWidget();
    QVBoxLayout *layout = new QVBoxLayout(widget);
    layout->addWidget(view);
    widget->show();

To copy to clipboard, switch view to plain text mode 

void hmi_cfg::closeEvent(QCloseEvent *event)
{
    qDebug()<<"Inside close event......."<<event;
}

void hmi_cfg::closeEvent(QCloseEvent *event)
{
    qDebug()<<"Inside close event......."<<event;
}
