[Qt-interest] Unable to load Google maps in Qt widgets through QWebview and evaluateJavaScript function

[Anisha Kaul]

Found the answer!

Any Javascript function which has to be called from function *
evaluateJavaScript* is supposed to defined in an html file read by the C++
source as shown below:

Now instead of creating a new add marker function, I have added its code in
the Open function defined below:

---------------------------
var map;

function initialize()
{
      if (GBrowserIsCompatible())
      {
            map = new GMap2(document.getElementById("map"));
            map.setCenter( new GLatLng(0,0),1 );
      }
    }

function Open (x,y)
{
    map.setCenter (new GLatLng(x,y), 13);

    var point = new GLatLng (x,y);
    map.addOverlay (new GMarker(point));
}
