\qmltype RouteSegment
\instantiates QDeclarativeGeoRouteSegment
\inqmlmodule QtLocation 5.0
\ingroup qml-QtLocation5-routing
\since Qt Location 5.0
\brief The RouteSegment element represents a segment of a Route.
A RouteSegment instance has information about the physical layout
of the route segment, the length of the route and estimated time required
to traverse the route segment and optional RouteManeuvers associated with
the end of the route segment.
RouteSegment instances can be thought of as edges on a routing
graph, with RouteManeuver instances as optional labels attached to the
vertices of the graph.
The primary means of acquiring Route elements is via Routes via \l RouteModel.
\section1 Example
The following QML snipplet demonstrates how to print information about a
route segment:
\snippet snippets/declarative/routing.qml QtQuick import
\snippet snippets/declarative/routing.qml QtLocation import
\codeline
\snippet snippets/declarative/routing.qml RouteSegment
