[Users] How to add event listener to the legend entry in legend panel

[Marc Jansen]

Hi Yingqi,

you could use the defaults property of the LegendPanel:

     var legendPanel = new GeoExt.LegendPanel({
         defaults: {
             labelCls: 'legendpanel-layername',
             style: 'padding:5px',
             clickableSymbol: true,
             clickableTitle: true,
             selectOnClick: true,
             listeners: {
                 symbolclick: function(comp, rule){ alert('symbolclick'); },
                 titleclick: function(comp, rule){ alert('titleclick'); },
                 ruleclick: function(comp, rule){ alert('ruleclick'); },
                 ruleselected: function(comp, rule){ 
alert('ruleselected'); }
             }
         },
         autoScroll: true
     });

Regards,

Marc
