QML: Component.onDestruction not calling on window close

[nestuser]

Hi,

I loaded a QML file using QDeclarativeview and continuously send some signals to the Qml file from cpp.
On window close of the qml file i need to stop the the signals. But how can I identify the window close of qml file?? I tried Component.onDestruction event of qml. But it is not getting. Please suggest a suitable method.
I tried closeEvent(). But this is also not hitting...

Thanks in advance.

CloseEvent() of which widget did you try? And how exactly did you "try" it?

[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;
}

What is hmi_cfg?

[nestuser]

That is the class name.

[wysota]

That is the class name.

Yes, I'm aware of that. I'm asking what this class is. Is this your top-level widget or some other widget or what exactly.

[nestuser]

Sorry, that was my mistake.
hmi_cfg was a subclass of QDeclarativeView.
I re implemented it as a subclass of QWidget, then I got the QCloseEvent correctly..

Thanks for your help..
