It seems like your question has nothing to do with development of Qt itself, so it would be more
appropriate to use "interest" mailing list.

As for your question, you can get id by using methods like QWindow::winId() or QWidget::effectiveWinId()
If subject window is not managed by Qt, you have to use native API.
