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 QtQuickimport QtPositioningimport QtLocationListView { 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"
