Android平台上的QWebView HTML5地理定位。

Attempting to get the GPS coordinates in a HTML5 web page viewed with Necessitas's port of QWebView. However it always responds with Not Supported.

试图在HTML5 web页面中使用必需的QWebView端口查看GPS坐标。然而，它总是响应不支持。

function load( )
{
   if ( navigator.geolocation )
   {
      alert( "Supported." );
   }
   else
   {
      alert( "Not Supported!" );
   }
}

I've altered the QWebPage to allow permissions:

我修改了qweb页面以允许权限:

BrowserWebPage::BrowserWebPage( QObject* parent ) : QWebPage( parent )
{
    connect( this,
             SIGNAL( featurePermissionRequested( QWebFrame*, QWebPage::Feature ) ),
             SLOT( permissionRequested( QWebFrame*, QWebPage::Feature ) ) );
}

void BrowserWebPage::permissionRequested( QWebFrame* frame, QWebPage::Feature feature )
{
    if ( feature == Geolocation )
    {
        setFeaturePermission( frame, feature, PermissionGrantedByUser );
    }
    else //denied
    {
        setFeaturePermission( frame, feature, PermissionDeniedByUser );
    }
}

And set the following permissions:

并设置以下权限:

android.permission.INTERNET

android.permission.ACCESS_FINE_LOCATION

android.permission.ACCESS_COARSE_LOCATION

EDIT

编辑

According to this page the GeoLocation API is present within the QtWebKit build.

根据这个页面，地理定位API出现在QtWebKit构建中。

I think you will have to set coarse location and internet permission because the fine location is only used for gps if im right. in any case having both is good cause if gps is not available the location over your internet connection will be used.

我认为你必须设置粗糙的位置和网络权限，因为好的位置只能用于gps，如果我是对的。在任何情况下，两者都有很好的原因，如果全球定位系统不可用，将使用您的互联网连接上的位置。

   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <uses-permission android:name="android.permission.INTERNET" />

I don't really have experience with qtwebkit but this is the basics i can tell you.

我没有使用qtwebkit的经验，但这是我可以告诉你的基本知识。
