I load a map with data and collect information in a JSON file. I want a tooltip appear when mousing over a town on the map.

   var vecLayer = new OpenLayers.Layer.Vector("vector", {
        styleMap: styleMap,
        protocol: new OpenLayers.Protocol.HTTP({
            // url: "app/data/summits.json",
            //url: "app/data/chargeIndicateur.php",
            url: "../web/app_dev.php/json/indicateur/"+gIndicateur+"/"+gEchelle+"/"+gPeriode,
            format: new OpenLayers.Format.GeoJSON(),
            idProperty: 'Issam'

        }),

, {
// dock: 'right',
xtype: 'toolbar',
id    : 'teste2',

items: [{
text: 'Nom',
labelStyle: 'font-weight:bold;',
}]
} ,
