get favicon of website

[pussbb]

how i can get a favicon of website
i try

QWebPage m_page;
QIcon icon =  m_page.mainFrame()->icon();
// and
m_page.settings()->iconForUrl(url);

QWebPage m_page;
QIcon icon =  m_page.mainFrame()->icon();
// and
m_page.settings()->iconForUrl(url);

To copy to clipboard, switch view to plain text mode 

even if favicon in html tag

//get favicon
    QWebElement document = m_page.mainFrame()->documentElement();
    QString icon_url = "";
    QWebElementCollection collection = document.findAll("link");
    foreach(QWebElement current_element, collection){
        if(current_element.hasAttribute("rel") && current_element.attribute("rel") == "icon"){
            qDebug()<<current_element.attribute("href");
            icon_url  = current_element.attribute("href");
        }
    }
Qicon icon = m_page.settings()->iconForUrl(url+ icon_url);

//get favicon
    QWebElement document = m_page.mainFrame()->documentElement();
    QString icon_url = "";
    QWebElementCollection collection = document.findAll("link");
    foreach(QWebElement current_element, collection){
        if(current_element.hasAttribute("rel") && current_element.attribute("rel") == "icon"){
            qDebug()<<current_element.attribute("href");
            icon_url  = current_element.attribute("href");
        }
    }
Qicon icon = m_page.settings()->iconForUrl(url+ icon_url);

To copy to clipboard, switch view to plain text mode 

but it always a default icon

If this is under windows:

Note: Web site icons, also known as "FavIcons", are currently not supported on Windows. We plan to address this in a future release.

no under linux kubuntu 11.04 qt 4.7

Qicon icon = m_page.settings()->iconForUrl(url+ icon_url);

Qicon icon = m_page.settings()->iconForUrl(url+ icon_url);

To copy to clipboard, switch view to plain text mode 

is the icon you get a valid icon?
Are you sure the site implements a special icon?

Returns the web site's icon for url.

If the web site does not specify an icon OR if the icon is not in the database, a null QIcon is returned.
