Qt WebKit and HTML5 geolocation

 

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:

 

1. window. onload = function ( )
2. {
3.     getMyLocation ( ) ;      
4. }
5.  
6. function getMyLocation ( )
7. {
8.     if (navigator. geolocation )
9.     {
10.         navigator. geolocation. getCurrentPosition (displayLocation ) ;        
11.     }  
12.     else
13.     {
14.         alert ( "No geolocation support" ) ;  
15.     }
16. }
17.  
18. function displayLocation (position )
19. {
20.     var latitude = position. coords. latitude ;
21.     var longitude = position. coords. longitude ;
22.    
23.     var div = document. getElementById ( "location" ) ;
24.    
25.     div [removed ] = "You are at Latitude: " + latitude + ", Longitude: " + longitude ;  
26. }

 

 

1. QWebView * MyWindow :: createWebView ( )
2.     {
3.         QWebSettings * default_settings = QWebSettings :: globalSettings ( ) ;
4.         default_settings -> setAttribute ( QWebSettings :: JavascriptEnabled , true ) ;
5.         default_settings -> setAttribute ( QWebSettings :: OfflineStorageDatabaseEnabled , true ) ;
6.         default_settings -> setAttribute ( QWebSettings :: OfflineWebApplicationCacheEnabled , true ) ;
7.         default_settings -> setAttribute ( QWebSettings :: LocalContentCanAccessRemoteUrls , true ) ;        
8.         default_settings -> setAttribute ( QWebSettings :: LocalStorageEnabled , true ) ;
9.         default_settings -> setAttribute ( QWebSettings :: JavascriptCanAccessClipboard , true ) ;
10.         default_settings -> setAttribute ( QWebSettings :: DeveloperExtrasEnabled , true ) ;
11.  
12.         QWebView * web_view = new QWebView ( this ) ;
13.  
14.         connect (web_view -> page ( ) -> mainFrame ( ) , SIGNAL (javaScriptWindowObjectCleared ( ) ) ,
15.                 this , SLOT (addJavascriptObject ( ) ) ) ;
16.  
17.         inspector_ -> setPage (web_view -> page ( ) ) ;
18.  
19.         inspector_ -> setVisible ( true ) ;
20.         inspector_ -> show ( ) ;
21.  
22.         web_view -> load ( QUrl ( "qrc:/html/geolocation_example.html" ) ) ;
23.        
24.         return web_view ;
25.     }

 

Anyone knows how to enable geolocation for a desktop app?
