我建了一个静态树，用window控件可以看到var mytree = new Ext.Window({
height : 500,
width : 400,
layout : 'fit',
border : false,
title : '我的树形',
items : staticTree
});
mytree.show();但是用TabPanel里的一个子页全显示不出来，如下var tabs = new Ext.TabPanel({
activeTab: 0,
frame:true,
items:[{
title: '指标考核',
layout:'border',
width:'auto',
/* listeners:{
activate:function(){alert('a')}
},*/
items:[{
region:'center',
title:'center'
},{
region:'west',
title:'west',
split:true,
width:300,
maxWidth:300,
items:staticTree
}]
},{
title: '过程监测'
},{
title: '指标仪表盘'
},{
title: '能耗评估'
},{
title: '更多'
}
]
});这是为什么的呢？小弟初学EXTJS，请高手们赐教

</html>经过测试没有问题，只是tabpanel如果不设置高度的话是出不来的。希望可以帮到楼主
然后renderTo:'myPanelId'即可渲染panel.
