[Qt-interest] Why does QWinWidget has a minimum size?

[cheng long]

I hosted a QGraphicsView with QWinWidget in a MFC CView and want to resize
the QWinWidget and QGraphicsView along with zooming. The issue is when width
< 26 and height < 8, QWinWidget::resize() fails to work. The QWinWidget
becomes a large square, while the QGraphicsView is still a smaller
rectangle. The area not occupied by QGraphicsView is gray, i.e. the
QWinWidget's background color. Any one experiences that? What's the problem?
Thanks!

Qt 4.5.2, Win7
Codes:
         QRectF sceneRect = view->scene()->itemsBoundingRect();
         QRect rect = view->mapFromScene(sceneRect).boundingRect();
         view->resize(rect.size()); // resize view
         CChildView::m_pWinWidget->resize(rect.size()); // resize QWinWidget
         view->scene()->items()[0]->setPos(view->mapToScene(0, 0)); //
center the QGraphicsItem

Thanks,
Kevin
