QCefView阻止新窗口并在同一窗口打开链接的方法

以QCefViewTest工程为例，需要在CefViewWidget类中重载onBeforePopup方法

bool CefViewWidget::onBeforePopup(qint64 frameId,
    const QString& targetUrl,
    const QString& targetFrameName,
    QCefView::CefWindowOpenDisposition targetDisposition,
    QCefSetting& settings,
    bool& DisableJavascriptAccess)
{
    QCefView::navigateToUrl(targetUrl);
    return true;
}
