Hi all,
what I'm trying to do is populate two textboxes with information from
microsoft VEMap which I have embeded in my html file.
To be more specific I want to show the latitude and longitude of the
point I click on.
The html file looks like this :
<html>
<head>
.................
<script language='javascript'
src='gr.urbantech.geopoints.Application.nocache.js'></script>
<script type="text/javascript" src="http://
dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.1"></script>
<script type="text/javascript">
var map = null;
function GetMap()
{
map = new VEMap('myMap' );
map.LoadMap(new VELatLong(41.11, 25.37 ),
8 ,'r' ,false);
map.AttachEvent("onmousedown",MouseHandler);
}
function MouseHandler(e)
{
if (e!=null)
{
if (e.rightMouseButton)
{
var x = e.mapX;
var y = e.mapY;
var ll = map.PixelToLatLong(new
VEPixel(x,y));
var lat=ll.Latitude; (it is a float value)
var long=ll.Longitude; (it is a float value)
alert(ll);
}
}
}
</script>
</head>
<body>
..............
<!-- OPTIONAL: include this if you want history support -->
<iframe src="javascript:''" id="__gwt_historyFrame"
style="width:0;height:0;border:0"></iframe>
....................
<table align=center>
<tr>
<td id="slot1"></td>
</tr>
</table>
<!--
<div id='myMap' style="position:relative; width:600px; height:
600px;"></div>
-->
</body>
</html>
And then onModuleLoad:
public void onModuleLoad() {
RootPanel slot = RootPanel.get("slot1");
HorizontalPanel hp =new HorizontalPanel();
VerticalPanel vp=new VerticalPanel();
String html = "<div id='myMap' style='position:relative; width:
500px; height:500px;'><//div>";
mapHtml = new HTML(html);
vp.add(mapHtml);
hp.add(vp);
//hp.add(mapPanel);
slot.add(hp);
callBrowserScript();
}
public static native void callBrowserScript() /*-{
$wnd.GetMap();
}-*/;
How can I pass the lat and long variables to gwt so as to be able to
fill my textboxes?
I have read the jsni documentation but was able to do only the
opposite thing which is to center the map to the coordinates I put in
the textboxes.
That is i can pass info from gwt to js but no the other way round.
Thanks in advance
