Transparent QWebView with Qt5

  • We used to use trick http://blog.qt.digia.com/blog/2009/06/30/transparent-qwebview-or-qwebpage/ to make QWebView transparent with Qt4 as following, but same code give us blank background with Qt 5.2. Is there any way I can make that work with Qt5?

    setAttribute(Qt::WA_TranslucentBackground, true);
    setWindowFlags(Qt::FramelessWindowHint | Qt::Tool);

    QPalette palette = m_pWebView->palette();
    palette.setBrush(QPalette::Base, Qt::transparent);
    m_pWebView->setAttribute(Qt::WA_OpaquePaintEvent, false);
