openlayers 2 - Click to Hover for WMSGetFeatureInfo

I am using the following code and wanted to know how I can change it from click event to hover or mousemove event. I know there is a eventListner but I am unable to locate the click event where I must change it to mousemove event.

info = new OpenLayers.Control.WMSGetFeatureInfo({

            url: 'http://localhost:8080/geoserver/iPlant/wms', 
            title: 'Identify features by clicking',
            queryVisible: true,
            eventListeners: {
                getfeatureinfo: function(event) {
                    map.addPopup(new OpenLayers.Popup.FramedCloud(
                        "chicken", 
                        map.getLonLatFromPixel(event.xy),
                        null,
                        event.text,

                        null,
                        true
                    ));
                }
            }
        });
        map.addControl(info);
        info.activate();

Update 2.0

I made the changes and also added the PopUp, but only the click function is being recognized.

info = {
            click: new OpenLayers.Control.WMSGetFeatureInfo({
            url : 'http://niles.iplantcollaborative.org:8080/geoserver/wms',
            title : 'Identify features by clicking',
            queryVisible : true,
            eventListeners : {
            getfeatureinfo : function(event) {
            deletePopUp();
            popup = new OpenLayers.Popup.FramedCloud("popInfo", map.getLonLatFromPixel(event.xy), null, event.text, null, true);

            map.addPopup(popup);}}
            }),
            hover: new OpenLayers.Control.WMSGetFeatureInfo({
            url : 'http://niles.iplantcollaborative.org:8080/geoserver/wms',
            title : 'Identify features by clicking',
            queryVisible : true,
                    hover : true,
            eventListeners : {
            getfeatureinfo : function(event) {
            deletePopUp();

            popup = new OpenLayers.Popup.FramedCloud("popInfo", map.getLonLatFromPixel(event.xy), null, event.text, null, true);
            map.addPopup(popup);
            }}
            })
            };
            map.addControl(info.hover);
            info.hover.activate();

Answer

you can add your code in object and then call whatever you want as following code.. actually OpenLayers.Control.WMSGetFeatureInfo has hover properties which enough for to solve your problem.

       info = {

        click: new OpenLayers.Control.WMSGetFeatureInfo({
            url: 'http://demo.opengeo.org/geoserver/wms', 
            title: 'Identify features by clicking',
            layers: [layer],
            queryVisible: true
        }),
        hover: new OpenLayers.Control.WMSGetFeatureInfo({
            url: 'http://demo.opengeo.org/geoserver/wms', 
            title: 'Identify features by clicking',
            layers: [layer],

            hover: true,                
            formatOptions: {
                typeName: 'water_bodies', 
                featureNS: 'http://www.openplans.org/topp'
            },
            queryVisible: true
        })
    };
     map.addControl(info.hover);
     info.hover.activate();

hover

{Boolean} Send GetFeatureInfo requests when mouse stops moving. Default is false.
