<h2>Detailed Description</h2>
<p>A place attribute stores an additional piece of information about a <a href="qml-qtlocation-place.html">Place</a> that is not otherwise exposed through the <a href="qml-qtlocation-place.html">Place</a> type. A PlaceAttribute is a textual piece of data, accessible through the <a href="qml-qtlocation-placeattribute.html#text-prop">text</a> property, and a <a href="qml-qtlocation-placeattribute.html#label-prop">label</a>. Both the <a href="qml-qtlocation-placeattribute.html#text-prop">text</a> and <a href="qml-qtlocation-placeattribute.html#label-prop">label</a> properties are intended to be displayed to the user. PlaceAttributes are stored in an <a href="qml-qtlocation-extendedattributes.html">ExtendedAttributes</a> map with a unique key.</p>
<p>The following example shows how to display all attributes in a list:</p>
<pre class="qml">import QtQuick 2.0
import QtPositioning 5.2
import QtLocation 5.0
<span class="type">ListView</span> {
<span class="name">model</span>: <span class="name">place</span>.<span class="name">extendedAttributes</span>.<span class="name">keys</span>()
<span class="name">delegate</span>: <span class="name">Text</span> {
<span class="name">text</span>: <span class="string">"<b>"</span> <span class="operator">+</span> <span class="name">place</span>.<span class="name">extendedAttributes</span>[<span class="name">modelData</span>].<span class="name">label</span> <span class="operator">+</span> <span class="string">": </b>"</span> <span class="operator">+</span>
<span class="name">place</span>.<span class="name">extendedAttributes</span>[<span class="name">modelData</span>].<span class="name">text</span>
}
}</pre>
<p>The following example shows how to assign and modify an attribute:</p>
<pre class="qml"> <span class="comment">//assign a new attribute to a place</span>
var <span class="name">smokingAttrib</span> = <span class="name">Qt</span>.<span class="name">createQmlObject</span>(<span class="string">'import QtLocation 5.0; PlaceAttribute {}'</span>, <span class="name">place</span>);
<span class="name">smokingAttrib</span>.<span class="name">label</span> <span class="operator">=</span> <span class="string">"Smoking Allowed"</span>
<span class="name">smokingAttrib</span>.<span class="name">text</span> <span class="operator">=</span> <span class="string">"No"</span>
<span class="name">place</span>.<span class="name">extendedAttributes</span>.<span class="name">smoking</span> <span class="operator">=</span> <span class="name">smokingAttrib</span>;
<span class="comment">//modify an existing attribute</span>
<span class="name">place</span>.<span class="name">extendedAttributes</span>.<span class="name">smoking</span>.<span class="name">text</span> <span class="operator">=</span> <span class="string">"Yes"</span></pre>
