@karti-gesar If I understood you correctly you want a way to close the QQuickView window using the Keys item in the QML loaded by that QQuickView. If so then there is a global Qt object that provides a quit method. As its description says you just have to connect that signal to your QQuickView's QQmlEngine and then call close on QQuickView.
Eg.
QML

Keys.onPressed: {
  ...
  Qt.quit()
  ...
}

CPP

view =new QQuickView;
connect(view->engine(), SIGNAL(quit()), view, SLOT(close()));
or
connect(view->engine(), &QQmlEngine::quit, view, &QQuickView::close);

Hope this helps...

@karti-gesar No. It is the global object available across all QML files.
