自己参照一下看看，有问题再发上来：Ext.onReady(function(){
    var SendCmd = new Ext.FormPanel({
                aotoHeight:true,
                buttonAlign:'center',
                border:false,
                bodyStyle:'padding: 10px 10px 10px 20px;',
                labelWidth:2,
                defaults:{
                        anchor:'95%',
                        allowBlank:false,
                        msgTarget:'side'
                },
                items:[{
                            xtype:'textarea',
                            id:'Result',
                            name:'Result',
                            height:200,
                            readOnly:true,
                            allowBlank:true
                         }, {
                             xtype:'textfield',
                             emptyText : '请输入...',
                             name:"Task",
                             id:"Task",
                             listeners:{'specialkey':function(_field,_e){
                                if (_e.getKey() == _e.ENTER){
                                    var str = Ext.getCmp('Result').getValue()+'\r\n'+Ext.getCmp('Task').getValue();
                                    Ext.getCmp('Result').setValue(str);
                                    document.all.Result.scrollTop=document.all.Result.scrollHeight;
                                }
                            }}
                         }]
            });
    var win=new Ext.Window({
        layout:'fit',
                title:"test",
        width:620,
        height:350,
        constrain: true,
        resizable:false,
        collapsible:true,
                closable:true,
        items:SendCmd
    });
    win.show();
});

没有代码啊。。
如果是动态添加的话，需要doLayout()
帖出代码来看看吧
