Extjs如何在beforeremove事件中得到当前将要关闭的tabId，我试过了。事件参数是为TabPanel的对象，而不是将要关闭Tab的对象.我想知道怎么获取
beforeremove : ( Ext.Container this, [color=red]Ext.Component component[/color] )
Fires before any Ext.Component is removed from the container. A handler can return false to cancel the remove.

Listeners will be called with the following arguments:
* this : Ext.Container
[color=red] * component : Ext.Component 这就是你所要的 将要关闭Tab的对象[/color]
The component being removed
[quote]beforeremove事件中[/quote]
beforeremove : ( Ext.Container this, Ext.Component component )
在任何Ext.Component 被从容器中移除之前触发。
Ext.Container this remove组件对象的容器
compoent remove的组件对象.
这里的component 可以用你的tapnel对象指定你关闭的当前的panel
比如tapnel.item[1]，这是关闭tapPanel中的第二个对象
