详细说明

地点属性存储了关于Place 的附加信息，这些信息无法通过Place 类型公开。placeAttribute 是一段文本数据，可通过text 属性和label 访问。l {placeAttribute::}{text} 和label 属性都是为了显示给用户看。placeAttribute 存储在一个具有唯一键的ExtendedAttributes 地图中。

下面的示例展示了如何在列表中显示所有属性：

import QtQuick
import QtPositioning
import QtLocation

ListView {
    model: place.extendedAttributes.keys()
    delegate: Text {
        text: "<b>" + place.extendedAttributes[modelData].label + ": </b>" +
              place.extendedAttributes[modelData].text
    }
}

下面的示例展示了如何分配和修改属性：

    //assign a new attribute to a place
    var smokingAttrib = Qt.createQmlObject('import QtLocation; PlaceAttribute {}', place);
    smokingAttrib.label = "Smoking Allowed"
    smokingAttrib.text = "No"
    place.extendedAttributes.smoking = smokingAttrib;

    //modify an existing attribute
    place.extendedAttributes.smoking.text = "Yes"
