Answer 1

getActiveTab()listeners:{// 添加监听器，点击此页面的tab时候要重新加载（刷新功能）
                                 activate:function(){
                                      this.getActiveTab().refresh(); //                                      Ext.MessageBox.alert("提示","系统参数信息");
                                 }
                            }
