如何将事件处理程序附加到extJS中的面板？

Ext.create('Ext.panel.Panel', {
    title: 'My Panel',
    width: 300,
    height: 200,
    renderTo: Ext.getBody(),
    listeners: {
        render: function(panel) {
            console.log('The panel has been rendered.');
        },
        click: function(panel, e) {
            console.log('The panel has been clicked.');
        }
    }
});
