ListElement 字段作为属性? [英] ListElement fields as properties?

问题描述

这是我的代码:

import QtQuick 1.0

ListModel {
    property real firstValue: 2
    property real secondValue: 3
    property real thirdValue: 1
    id: leftGrid
    ListElement {
        icon: "Images/1.png"
        value: leftGrid.firstValue
    }
    ListElement {
        icon: "2.png"
        value: -1
    }
    ListElement {
        icon: "3.png"
        value: leftGrid.secondValue
    }
    ListElement {
        icon: "4.png"
        value: leftGrid.thirdValue
    }
}

这给了我错误:

ListElement: cannot use script for property value

我该怎么办?
