<h2 id="details">Detailed Description</h2>
</p>
<p>The <a href="qml-qtlocation-routemodel.html">RouteModel</a> type is used as part of a model/view grouping to retrieve geographic routes from a backend provider. Routes include data about driving directions between two points, walking directions with multiple waypoints, and various other similar concepts. It functions much like other Model types in QML (see for example ListModel and XmlListModel), and interacts with views such as <a href="qml-qtlocation-mapitemview.html">MapItemView</a>, and ListView.</p>
<p>Like <a href="qml-qtlocation-map.html">Map</a> and <a href="qml-qtlocation-geocodemodel.html">GeocodeModel</a>, all the data for a <a href="qml-qtlocation-routemodel.html">RouteModel</a> to work comes from a services plugin. This is contained in the <a href="location-places-qml.html#plugin">plugin</a> property, and this must be set before the <a href="qml-qtlocation-routemodel.html">RouteModel</a> can do any useful work.</p>
<p>Once the plugin is set, create a <a href="qml-qtlocation-routequery.html">RouteQuery</a> with the appropriate waypoints and other settings, and set the <a href="qml-qtlocation-routemodel.html">RouteModel</a>'s <a href="qml-qtlocation-routemodel.html#query-prop">query</a> property. If <a href="qml-qtlocation-routemodel.html#autoUpdate-prop">autoUpdate</a> is enabled, the update will being automatically. Otherwise, the <a href="qml-qtlocation-routemodel.html#update-method">update</a> method may be used. By default, <a href="qml-qtlocation-routemodel.html#autoUpdate-prop">autoUpdate</a> is disabled.</p>
<p>The data stored and returned in the <a href="qml-qtlocation-routemodel.html">RouteModel</a> consists of <a href="qml-qtlocation-route.html">Route</a> objects, as a list with the role name "routeData". See the documentation for <a href="qml-qtlocation-route.html">Route</a> for further details on its structure and contents.</p>
<a name="example-usage"></a>
<h3 >Example Usage</h3>
<p>The following snippet is two-part, showing firstly the declaration of objects, and secondly a short piece of procedural code using it. We set the routeModel's <a href="qml-qtlocation-routemodel.html#autoUpdate-prop">autoUpdate</a> property to false, and call <a href="qml-qtlocation-routemodel.html#update-method">update</a> once the query is set up, to avoid useless extra requests halfway through the set up of the query.</p>
