[OpenLayers-Users] Mouse.Default help

[bradleyspencer]

Christopher,

Sorry to do this but I am unable to get this working.

I am using the following code to make double click work as a getFeatuerInfo
request but double click on the map still re-centres the map?

OpenLayers.Control.MouseDefaults.prototype.defaultDblClick = function(e)
{
var getFeatureInfoRequest =  landuse.getFullRequestString
	({
		REQUEST: "GetFeatureInfo",
                	//EXCEPTIONS: "application/vnd.ogc.se_xml",
		EXCEPTIONS: "bxfs",
                	BBOX: landuse.map.getExtent().toBBOX(),
                	X: e.xy.x,
                	Y: e.xy.y,
		INFO_FORMAT: 'text/html',
		QUERY_LAYERS: landuse.params.LAYERS,
		QUERY_LAYERS: queryLayers ,
               	WIDTH: landuse.map.size.w,
               	HEIGHT: landuse.map.size.h
	});
	makePopup(getFeatureInfoRequest,'1200','480','both');
        	Event.stop(e);
}

FF is not objecting to this code. Is there something I am doing obviously
wrong here?

The application can be tested at http://demo.cubewerx.com.au/DemoDrapes.html

Thanks in advance.

Cheers,

If you only want to do it for one control (for example, when you only
have one map in the page):

 control = new OpenLayers.Control.MouseDefaults();
 control.defaultDblClick = function(evt) {
   var point = this.map.getLonLatFromViewPortPx( evt.xy );
   alert("Got point:" + point);
   OpenLayers.Event.stop(evt);
   return false;
 }

If you have multiple maps, or don't want to change the default controls
when creating the map:

 OpenLayers.Control.MouseDefaults.prototype.defaultDblClick = function(evt)
{
   var point = this.map.getLonLatFromViewPortPx( evt.xy );
   alert("Got point:" + point);
   OpenLayers.Event.stop(evt);
   return false;
 }
