    QString standardFontFamily = defaultSettings->fontFamily(QWebSettings::StandardFont);
    int standardFontSize = defaultSettings->fontSize(QWebSettings::DefaultFontSize) +;
    QFont standardFont = QFont(standardFontFamily, standardFontSize);
    standardFont = (settings.value(QLatin1String("standardFont"), standardFont)).value<QFont>();
    defaultSettings->setFontFamily(QWebSettings::StandardFont, standardFont.family());
    defaultSettings->setFontSize(QWebSettings::DefaultFontSize, standardFont.pointSize());
 
    QString fixedFontFamily = defaultSettings->fontFamily(QWebSettings::FixedFont);
    int fixedFontSize = defaultSettings->fontSize(QWebSettings::DefaultFixedFontSize);
    QFont fixedFont = QFont(fixedFontFamily, fixedFontSize);
    fixedFont = (settings.value(QLatin1String("fixedFont"), fixedFont)).value<QFont>();
    defaultSettings->setFontFamily(QWebSettings::FixedFont, fixedFont.family());
    defaultSettings->setFontSize(QWebSettings::DefaultFixedFontSize, fixedFont.pointSize());
 
    bool zoom_text_only = settings.value(QLatin1String("zoom_text_only"), false).toBool();
    defaultSettings->setAttribute(QWebSettings::ZoomTextOnly, zoom_text_only);
 
    defaultSettings->setAttribute(QWebSettings::JavascriptEnabled, settings.value(QLatin1String("enableJavascript"), true).toBool());

    QLatin1String localStoragePath ;
    defaultSettings->setLocalStoragePath(localStoragePath);
    defaultSettings->setOfflineStoragePath(localStoragePath);
    defaultSettings->setOfflineWebApplicationCachePath(localStoragePath);
 
    defaultSettings->setIconDatabasePath(dataLocation());
 
    QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled,true);
    QWebSettings::globalSettings()->setWebGraphic(QWebSettings::MissingImageGraphic, QPixmap());@
