Hi list,
is it possible to construct GetFeatureInfo machanism with popup which will
be active only on objects (points, lines, polygons) from WMS layers. I
already have popups working on my whole map. When I click outside of object
e.g polygon the opened popup is empty. I would like to have popups which
apear only on objects (or more precisely, only on places where
GetFeatureInfo information is present).
This is GetFeatureInfo code which I use:
info = new OpenLayers.Control.WMSGetFeatureInfo({
url: 'http://webgis.24gis.pl/geoserver/wms',
title: 'Identify features by clicking',
queryVisible: true,
infoFormat: 'text/html',
maxFeatures: 1,
eventListeners: {
getfeatureinfo: function(event) {
popup = new OpenLayers.Popup.FramedCloud(
"chicken",
map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
), {
autoSize: false,
maxSize: new OpenLayers.Size(5,5)
};
map.addPopup(popup);
}
}
});
map.addControl(info);
Thank you in advance for any sugestion!
Michal
