[OpenLayers-Dev] coodinates to use in LonLat

[Gajera Tejas]

Leonardo,

If I understood your question correctly, let say you want to zoom at
the position where you double click and make that as center of your
map.

I would do something like this:

// register double click event to map
map.events.register("dblclick", map, function(e) { onMapDoubleClick(e) });

// in onMapDoubleClick function get the lon and lat of the point where
you double clicked and next zoom level
function onMapDoubleClick(e)
{
	zoomLevel = zoomLevel + 1;
	var lonlat = map.getLonLatFromViewPortPx(e.xy);
	
	if(zoomLevel > mapMaxZoom)
	{
		gCurrentZoomLevel = mapMaxZoom;
		return;
	}
	else
	{
		map.setCenter(new OpenLayers.LonLat(lonlat.lon, lonlat.lat), zoomLevel);
	}
}

hope it will help you.
