Can I get a geolocation sample for the Qt?
I have some map samples, but not a开发者_如何学编程 geolocation one.
This link has an example.
class MyClass : public QObject
{
Q_OBJECT
public:
MyClass(QObject *parent = 0)
: QObject(parent)
{
QGeoPositionInfoSource *source = QGeoPositionInfoSource::createDefaultSource(this);
if (source) {
connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)),
this, SLOT(positionUpdated(QGeoPositionInfo)));
source->startUpdates();
}
}
private slots:
void positionUpdated(const QGeoPositionInfo &info)
{
qDebug() << "Position updated:" << info;
}
};
<script>
function success(position) {
var position={"coords":{"latitude":"18.520469","longitude":"73.856621"}};
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcanvas';
mapcanvas.style.height = '400px';
mapcanvas.style.width = '560px';
document.querySelector('article').appendChild(mapcanvas);
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeControl: false,
navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map,
title:"You are here!"
});
}
function error(msg) {
// console.log(arguments);
}
if (navigator.geolocation) {
//navigator.geolocation.getCurrentPosition(success, error);
} else {
error('not supported');
}
success("position");
</script>
