I'am triying to get the results of a googlemap function, from the javascript code back to the c++ source code in order to process those results. But no success.
I have an html page which I load inside a class derived from QWebView. The html page I load inside the WebView is:
Qt Code: 
  1. <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=GOOGLE_MAPS_KEY"
  2.       type="text/javascript"></script>
  3. 	<script type="text/javascript"> 
  4.  
  5. 	var map;
  6.   	var geocoder;
  7. 	var Lat,Lng;
  8.  
  9. 	function initialize()
  10. 	{
  11. 		  if (GBrowserIsCompatible()) 
  12. 		  {
  13.   				map = new GMap2(document.getElementById("map"));
  14. // 				 
  15. 				 map.addControl(new GSmallMapControl);
  16. 				 map.addControl(new GMapTypeControl);
  17. 				 geocoder = new GClientGeocoder();
  18. 				 map.setCenter( new GLatLng(0,0),1 );
  19. 				 GEvent.addListener(map, "click", getAddress);
  20. 		  }
  21.  
  22.     	}
  23.  
  24. 	function getAddress(overlay, latlng) {
  25.  
  26.      		 if (latlng != null) {
  27.  
  28.      		   address = latlng;
  29.  
  30.        		 geocoder.getLocations(latlng, showAddress);
  31.  
  32.       		}
  33.     	}
  34. 	function showAddress(response) {
  35. 		map.clearOverlays();
  36. 		if (!response || response.Status.code != 200) {
  37. 		alert("Status Code:" + response.Status.code);
  38. 		} else {
  39. 		place = response.Placemark[0];
  40. 		point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]);
  41. 		marker = new GMarker(point);
  42. 		map.addOverlay(marker);
  43. 		marker.openInfoWindowHtml(
  44. 			'<b>orig latlng:</b>' + response.name + '<br/>' + 
  45. 			'<b>latlng:</b>' + place.Point.coordinates[1] + "," + place.Point.coordinates[0] + '<br>' +
  46. 			'<b>Status Code:</b>' + response.Status.code + '<br>' +
  47. 			'<b>Status Request:</b>' + response.Status.request + '<br>' +
  48. 			'<b>Address:</b>' + place.address + '<br>' +
  49. 			'<b>Accuracy:</b>' + place.AddressDetails.Accuracy + '<br>' +
  50. 			'<b>Country code:</b> ' + place.AddressDetails.Country.CountryNameCode);
  51. 		Lat = place.Point.coordinates[1];
  52. 		Lng = place.Point.coordinates[2];
  53. 		Name= plcae.AddressDetails.Country.AdmninistrativeArea.Locality;
  54. 		 Map.setValues(Lat, Lng, Name); 
  55.  
  56. 		}
  57. }
  58. 	function Open(x,y)
  59. 	{
  60. 	  map.setCenter( new GLatLng(x,y),13 );
  61. 	}
  62.     </script> 
  63.  
  64.  </head>
  65.   <body onload="initialize()" onunload="GUnload()"   topmargin="0" leftmargin="0">

In my c++ code I have
Qt Code: 
  1. this->page()->mainFrame()->addToJavaScriptWindowObject("Map", this);
  2.  connect(page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()),
  3.             this, SLOT(populateJavaScriptWindowObject()));
  4. .....
  5. void Map::geoCode(QString local)
  6. {
  7. 	clearCoordinates();
  8. // 	qDebug()<<"Map finding..."<<local;
  9. 	QString requestStr( tr("http://maps.google.com/maps/geo?q=%1&output=%2&key=%3")
  10. 			.arg(local)
  11. 			.arg("csv")
  12. 			.arg("GOOGLE_MAPS_KEY") );
  13.  
  14. 	manager->get( QNetworkRequest(requestStr) );
  15. 	++pendingRequests;
  16. }
  17. ...
  18. void Map::populateJavaScriptWindowObject()
  19. {
  20. 	this->page()->mainFrame()->addToJavaScriptWindowObject("Map", this);
  21.  
  22. }
  23. void Map::setValues(const QString &latitude, const QString &longitude, const QString &n)
  24. {
  25. 	lat = latitude.toDouble();
  26. 	lon = longitude.toDouble();
  27. 	name = n;
  28. 	qDebug()<<"MAP new values available";
  29. }

So, I am expecting that when I click on a point in the google map the javascript calls the object Map, which I exported with the addToJavaScriptWindowObject.
But, nothing: I double click on a point, the map change but it seems that the setValues faunction is not call at all.
