<h2 id="details">Detailed Description</h2>
<p>The <a href="qgeoroutingmanager.html">QGeoRoutingManager</a> class provides support for geographic routing operations.</p>
<p>The <a href="qgeoroutingmanager.html#calculateRoute">calculateRoute</a>() and <a href="qgeoroutingmanager.html#updateRoute">updateRoute</a>() methods function <a href="qgeoroutereply.html">QGeoRouteReply</a> objects, which manage these operations and report on the result of the operations and any errors which may have occurred.</p>
<p>The <a href="qgeoroutingmanager.html#calculateRoute">calculateRoute</a>() function is used to find a route (or routes) that follows a set of waypoints and matches various other criteria. The <a href="qgeorouterequest.html">QGeoRouteRequest</a> class is used to specify this information.</p>
<p>If supportsRouteUpdates() returns true then the <a href="qgeoroutingmanager.html">QGeoRoutingManager</a> supports updating route information based on position updates. This will cause the travel time and distance estimates to be updated, and any QGeoRouteSegments already traversed to be removed from the route.</p>
<p>The updates can be triggered with the <a href="qgeoroutingmanager.html#updateRoute">updateRoute</a>() function, which makes use of the QGeoPositionInfo instances emitted as position updates by QGeoPositionInfoSource.</p>
<p>Instances of <a href="qgeoroutingmanager.html">QGeoRoutingManager</a> can be accessed with <a href="qgeoserviceprovider.html#routingManager">QGeoServiceProvider::routingManager</a>().</p>
