Qt WebKit and HTML5 geolocation

[mugen731]

I'm learning HTML5 and testing the new features on a Qt hybrid application.
Now I'm working on a simple geolocation example but when I call navigator.geolocation.getCurrentPosition(displayLocation); it seems the QtWebKit does not support it, but acording to this http://trac.webkit.org/wiki/QtWebKitFeatures22 the version of QtWebKit that comes with Qt4.8.0 supports geolocation.

This is the code I'm using:

@
window.onload = function()
{
getMyLocation();
}

function getMyLocation()
{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(displayLocation);
}
else
{
alert("No geolocation support");
}
}

function displayLocation(position)
{
var latitude = position.coords.latitude;
var longitude = position.coords.longitude;

var div = document.getElementById("location");

div[removed] = "You are at Latitude: " + latitude + ", Longitude: " + longitude;   

}

QWebView* MyWindow::createWebView()
{
QWebSettings* default_settings = QWebSettings::globalSettings();
default_settings->setAttribute(QWebSettings::JavascriptEnabled,true);
default_settings->setAttribute(QWebSettings::OfflineStorageDatabaseEnabled,true);
default_settings->setAttribute(QWebSettings::OfflineWebApplicationCacheEnabled,true);
default_settings->setAttribute(QWebSettings::LocalContentCanAccessRemoteUrls,true);
default_settings->setAttribute(QWebSettings::LocalStorageEnabled,true);
default_settings->setAttribute(QWebSettings::JavascriptCanAccessClipboard,true);
default_settings->setAttribute(QWebSettings::DeveloperExtrasEnabled,true);

    QWebView* web_view = new QWebView(this);

    connect(web_view->page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()),
            this, SLOT(addJavascriptObject()));

    inspector_->setPage(web_view->page());

    inspector_->setVisible(true);
    inspector_->show();

    web_view->load(QUrl("qrc:/html/geolocation_example.html"));
    
    return web_view;
}

Anyone knows how to enable geolocation for a desktop app?
