详细描述

A place attribute stores an additional piece of information about a Place that is not otherwise exposed through the Place type. A placeAttribute is a textual piece of data, accessible through the text property, and a label . Both the l {placeAttribute::}{text} and label properties are intended to be displayed to the user. placeAttributes are stored in an ExtendedAttributes map with a unique key.

The following example shows how to display all attributes in a list:

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

The following example shows how to assign and modify an attribute:

    //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"
