How to use QtWebkit with geolocation?

[brcontainer]

It is possible to use geolocation in Desktop applications with QWebView?

I tried set PermissionGrantedByUser, but not work:


void WebPage::permissionRequested(QWebFrame* frame, Feature feature)
{
switch (feature) {
case Geolocation:
qDebug() << "GEO-Location: PermissionGrantedByUser";
setFeaturePermission(frame, feature, PermissionGrantedByUser);
break;
default:
qDebug() << "";
}
}

I tried add this QT += positioning, but not work
I tried add this TARGET.CAPABILITY += NetworkServices Location, but not work, I believe this is for smartphones, like Symbian.


Event displayLocation and watchPosition are never fired and using {timeout: ...} it shows the message Timeout expired:


<script>
function displayError(err) {
document.getElementById("geo").innerHTML = ("Error Code: " + err.code +
" / msg: " + err.message);
}

function displayLocation(position) {
document.getElementById("geo").innerHTML = [
"latitude:" + position.coords.latitude,
"longitude:" + position.coords.longitude
].join(", ");
}

function getMyLocation() {
if (navigator.geolocation) {
navigator.geolocation.watchPosition(function(a, b, c) {
console.log(a, b, c);
document.getElementById("geo").innerHTML = "Testando...";
});
navigator.geolocation.getCurrentPosition(displayLo cation, displayError, {
enableHighAccuracy: false,
timeout: 10000,
maximumAge: 0
});
} else {
document.getElementById("geo").innerHTML = "No geolocation support";
}
}

window.onload = function() {
getMyLocation();
};
</script>
<div id="geo"></div>
I believe that I have to build a library and put in the qtDir/compiler/plugins/position

How can I do this?

Or is it possible to customize the event and send coordinates of a 3rdparty lib (I'm not asking for a library and I'm not asking for alternatives in javascript) in response to the navigator.geolocation.getCurrentPosition?

If use QT_DEBUG_PLUGINS=1 in debug mode Application Output return this (note that the first line is generated by WebPage.permissionRequested):

Any idea how to do this?
