錯誤：XmlListModel不是一個類型

Question

我在QML使用XmlListModel：

的XML：

<? xml version="1.0" ?> 
<queuelist> 
    <queue id="1" name="name" image="image.svg" turn="34" wait="50" /> 
</queuelist> 

的XmlListModel

XmlListModel { 
     id: queueModel 
     source: "queuelist.xml" 
     query: "/queuelist/queue" 
     XmlRole {name: id; query: "@id/string()"} 
     XmlRole {name: queue; query: "@name/string()"} 
     XmlRole {name: image; query: "@image/string()"} 
     XmlRole {name: turn; query: "@turn/string()"} 
     XmlRole {name: wait; query: "@wait/string()"} 
    } 

的QTCreator錯誤：

/home/(...)/Qt5.0.1/5.0.1/gcc/bin/qmlscene exited with code 255
