Thanks for answers.
*Oleg Shparber*, i already look on it, but haven't idea, how to render
<something like this> on widget.
*Samuel Rødal*, you perfectly right!
QQuickView accept only QWindow, so the only way is use windowHandle().
When i wrote "new QQuickView(windowHandle());" in first line of QWidget
subclass constructor, new QWindow with QuickView, separated from widget's
QWindow, was created.
When i wrote same code after line such "setWindowTitle("Title");", it does
But all works fine, when QQuickView created after subclass constructor,
like here:
    CMyWidget widget;
    QQuickView view(widget.windowHandle());
Quick test show few mouse events issues (i.e. When button overlapped by
view and mouse moved from button to view, button doesn't become
unhovered.), but it's enough good solution.
Thanks you very much.
