Ext.grid.Panel - how to access row data

I have an Ext.grid.Panel with a listener for dblclick. It looks like this:

listeners: {
    dblclick: {
        fn : function() {

               console.log("double click event processed");
        },
        element: 'el'
    }                
}

When a row is double clicked, I would like to open a URL in a new page. In order to determine the URL, I need access to row data - either that, or to the "row" in my JSON that serves as the Panel's store. How would I access this data?

Well, the event is itemdblclick (no dblclick). And the row is passed as an argumento to the handler.

For example, in the follow sample, when you double click on a row you can see an alert pop-up window displaying the selected Simpson name:

Ext.create('Ext.data.Store', {
    storeId:'simpsonsStore',
    fields:['name', 'email', 'phone'],
    data:{'items':[
        { 'name': 'Lisa',  "email":"[email protected]",  "phone":"555-111-1224"  },
        { 'name': 'Bart',  "email":"[email protected]",  "phone":"555-222-1234" },
        { 'name': 'Homer', "email":"[email protected]",  "phone":"555-222-1244"  },
        { 'name': 'Marge', "email":"[email protected]", "phone":"555-222-1254"  }
    ]},
    proxy: {
        type: 'memory',
        reader: {
            type: 'json',
            root: 'items'
        }
    }
});

Ext.create('Ext.grid.Panel', {
    title: 'Simpsons',
    store: Ext.data.StoreManager.lookup('simpsonsStore'),
    columns: [
        { text: 'Name',  dataIndex: 'name' },
        { text: 'Email', dataIndex: 'email', flex: 1 },
        { text: 'Phone', dataIndex: 'phone' }
    ],
    height: 200,
    width: 400,
    listeners: {
        itemdblclick: {
           fn : function(grid, record) {
               alert(record.get('name'));
           }
        }
    },                

    renderTo: Ext.getBody()
});​

You also can see it working here: http://jsfiddle.net/lontivero/utjyd/1/

Good luck!
