<h2>Detailed Description</h2>
<p>The MapObjectView is used to populate Map with MapObjects from a model. The MapObjectView element only makes sense when contained in a Map object, meaning that it has no standalone presentation.</p>
<p>Note: For model data, currently only <a href="qml-landmarkmodel.html">LandmarkModel</a> is supported. Using other types of models results in undefined behavior.</p>
<p>Assuming you have a <a href="qml-landmarkmodel.html">LandmarkModel</a> identified by landmarkModel, an example usage:</p>
<pre class="qml"> <span class="type"><a href="qml-map.html">Map</a></span> {
<span class="name">id</span>: <span class="name">map</span>
<span class="name">plugin</span> : <span class="name">Plugin</span> { <span class="name">name</span> : <span class="string">"nokia"</span> }
<span class="name">anchors</span>.fill: <span class="name">parent</span>; <span class="name">size</span>.width: <span class="name">parent</span>.<span class="name">width</span>; <span class="name">size</span>.height: <span class="name">parent</span>.<span class="name">height</span>; <span class="name">zoomLevel</span>: <span class="number">12</span>
<span class="name">center</span>: <span class="name">myPositionSource</span>.<span class="name">position</span>.<span class="name">coordinate</span>
<span class="type">MapObjectView</span> {
<span class="name">id</span>: <span class="name">circle_basic_view</span>
<span class="name">model</span>: <span class="name">landmarkModel</span>
<span class="name">delegate</span>: <span class="name">Component</span> {
<span class="name">id</span>: <span class="name">circleMapDelegate</span>
<span class="type"><a href="qml-mapcircle.html">MapCircle</a></span> {
<span class="name">color</span>: <span class="string">"red"</span>
<span class="name">radius</span>: <span class="number">500</span>
<span class="name">center</span>: <span class="name">landmark</span>.<span class="name">coordinate</span>
}
}
}</pre>
<p>The MapObjectView element is part of the <b>QtMobility.location 1.2</b> module.</p>
