\qmltype MapRoute
\instantiates QDeclarativeRouteMapItem
\inqmlmodule QtLocation
\ingroup qml-QtLocation5-maps
\since QtLocation 5.0
\brief The MapRoute type displays a Route on a Map.
The MapRoute type displays a Route obtained through a RouteModel or
other means, on the Map as a Polyline following the path of the Route.
MapRoute is really a \l MapPolyline, but with the path specified using the
\l route property instead of directly in \l {coordinate}{coordinates}.
By default, the route is displayed as a 1-pixel thick black line. This can
be changed using the \l line.width and \l line.color properties.
\section2 Performance
For notes about the performance on MapRoute, refer to the documentation for
\l MapPolyline.
\section2 Example Usage
Here is how to draw a \l{Route}{route} on a \l{Map}{map}:
\snippet declarative/maps.qml QtQuick import
\snippet declarative/maps.qml QtLocation import
\codeline
\snippet declarative/maps.qml MapRoute
*/
/*!
\qmlpropertygroup Location::MapRoute::line
\qmlproperty int MapRoute::line.width
\qmlproperty color MapRoute::line.color
This property is part of the line property group. The line
property group holds the width and color used to draw the line.
The width is in pixels and is independent of the zoom level of the map.
The default values correspond to a black border with a width of 1 pixel.
For no line, use a width of 0 or a transparent color.
