Icrease esri.geometry.Point tolerance

[BorjaSancho]

Hi all,

I need to increase the tolerance of my map points. Before I use icons and there is no problem with event control, but now i need to use text. I tried solutions like http://forums.esri.com/Thread.asp?c=158&f=2396&t=261892 but i think this is not useful for me because i don't use rest services.

I show my code

       //call method

 var geo = new esri.geometry.Point(xPos,yPos,new esri.SpatialReference({ wkid: 25830 }));
 var ip = new esri.Graphic(geo, null);
 var attr = {"xPos":xPos,"yPos":yPos,"id":id,"tactica":tactica,"estado":estado,"areaOp":areaOp,"fecha":fecha,"tipo":"incidente"};
 ip.setAttributes(attr);

        myInfoWindowXY(ip,icon);

        .....


function myInfoWindowXY(elemento,icono){
 try{
  var imageSymbol = new Image();
  imageSymbol.setAttribute('width', '16px');
  imageSymbol.setAttribute('height', '16px'); 
  imageSymbol.src = icono;
  
  //Seleccionamos, en funcion del tipo de punto, la capa sobre la que vamos a trabajar
  //si la capa no existe, la creamos
  if(elemento.attributes.tipo == "incidente"){
   if (gvdiDefaultMap.getLayer("IncidentPointsGraphicsLayer") == undefined){
    var incidentsLayer = new esri.layers.GraphicsLayer({id:"IncidentPointsGraphicsLayer"});
    gvdiDefaultMap.addLayer(incidentsLayer);
   }
   gvdiCurrentGraphicsLayer =  gvdiDefaultMap.getLayer("IncidentPointsGraphicsLayer");
      
  }else if (elemento.attributes.tipo == "llamadaSimple"){
   if (gvdiDefaultMap.getLayer("AlertPointsGraphicsLayer") == undefined){
    var alertsLayer = new esri.layers.GraphicsLayer({id:"AlertPointsGraphicsLayer"});
    gvdiDefaultMap.addLayer(alertsLayer);
   }
   gvdiCurrentGraphicsLayer =  gvdiDefaultMap.getLayer("AlertPointsGraphicsLayer");
   
  }else if (elemento.attributes.tipo == "recurso"){
   if (gvdiDefaultMap.getLayer("ResourcesPointsGraphicsLayer") == undefined){
    var resourcesLayer = new esri.layers.GraphicsLayer({id:"ResourcesPointsGraphicsLayer"});
    gvdiDefaultMap.addLayer(resourcesLayer);
   }
   gvdiCurrentGraphicsLayer =  gvdiDefaultMap.getLayer("ResourcesPointsGraphicsLayer");
   
  }else if (elemento.attributes.tipo == "llamadaMovil"){
   if (gvdiDefaultMap.getLayer("MobilePointsGraphicsLayer") == undefined){
    var mobileLayer = new esri.layers.GraphicsLayer({id:"MobilePointsGraphicsLayer"});
    gvdiDefaultMap.addLayer(mobileLayer);
   }
   gvdiCurrentGraphicsLayer =  gvdiDefaultMap.getLayer("MobilePointsGraphicsLayer");
  }
  
  //Añadimos el punto de geolocalizacion con su grafico asociado a la capa pertinente
  
  var displayText = elemento.attributes.tactica;

  var textSymbol;
   textSymbol = new esri.symbol.TextSymbol(displayText,font,new dojo.Color("#FE2E2E"));

  gvdiCurrentGraphicsLayer.add(elemento.setSymbol(textSymbol)); 
  
  //gvdiCurrentGraphicsLayer.add(elemento.setSymbol(esri.symbol.PictureMarkerSymbol(icono,imageSymbol.width,imageSymbol.height)));
  

  //Generamos los eventos correspondientes a los clics de raton
