QWindow, how to keep one always on top of another one?
<p>For two QWindow W1 &amp; W2.
Is there a way to make W2 always on top of W1?
The current method I use is to set W2 always on top by  <code>Qt::WindowStaysOnTopHint</code>.</p>

<p>But it also block the modal dialog when the dialog appear behind the window.
How can I make sure W2 on top of W1 without blocking the modal dialog?</p>

<p>I use QWindow because W2 is a QQuickView, which is not QWidget.</p>

<p>I am working on windows.</p>
