placeAttribute QML Value Type

placeAttribute 类型用于存储通用位置属性信息。更多内容...

Import Statement:	`import QtLocation 6.12`
Since:	QtLocation 5.5

属性

label : string
text : string

详细说明

“place”属性用于存储有关Place 的额外信息，这些信息无法通过Place 类型直接获取。 placeAttribute 是一段文本数据，可通过text 属性访问，并属于label 类型。l {placeAttribute::}{text} 和label 这两个属性均旨在向用户显示。placeAttributes 存储在ExtendedAttributes 映射中，并使用唯一键进行标识。

以下示例演示了如何将所有属性以列表形式显示：

import QtQuick
import QtPositioning
import QtLocation

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

以下示例演示了如何设置和修改属性：

    //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"
