Answer 1

[code="java"]
var tabs = Ext.createWidget('tabpanel', {
renderTo: 'tabs1',
width: 450,
activeTab: 0,
defaults :{
bodyPadding: 10
},

    listeners:{
            afterrender:function(tab){
                var tabBar = tab.down("tabbar");
                 tab.mon(tabBar.el, {
                    scope: this,
                    dblclick:function(){
                        tabs.remove(tab.getActiveTab());
                    },
                    delegate: 'div.x-tab'
                });

            }
    },

[/code] 关键是这几行代码：
var tabBar = tab.down("tabbar");
tab.mon(tabBar.el, {
scope: this,
dblclick:function(){
tabs.remove(tab.getActiveTab());
},
delegate: 'div.x-tab'
});
