[Rainer Wiesenfarth]

Hi Sujan,

I did not follow the rest of the discussion, but at least your sample code
contains an error:

The above line *replaces *your previously created window, including the
flags you set on it. Maybe this works:

...
// Part 1
QWindow *window = QWindow::fromWinId((WId)id);
window->setFlags(Qt::Desktop | Qt::ForeignWindow | Qt::WindowTitleHint);
QWidget *widget = QWidget::createWindowContainer(window);
...


    QWidget  *widget = QWidget::createWindowContainer(window);
