EXTJS中如何获得TabPanel的各个tab的点击事件

直接给Panel 添加监听（show）事件，即可实现。【不仅仅首次点击有效哦】

 listeners: {
                   'show': function (t, eOpts) {
                       alert(1);
                   }
               }

完整代码

var attinfocondition = Ext.create('Ext.panel.Panel',
           {
               xtype: 'panel',
               title: '使用条件',
