import 语句: | import QtLocation 5.15 |
Since: | QtLocation 5.0 |
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 MapPolyline , but with the path specified using the route property instead of directly in coordinates .
By default, the route is displayed as a 1-pixel thick black line. This can be changed using the line.width and line.color 特性。
For notes about the performance on MapRoute, refer to the documentation for MapPolyline .
Here is how to draw a route 在 map :
import QtQuick 2.0 import QtPositioning 5.5 import QtLocation 5.6 Map { RouteModel { id: routeModel } MapItemView { model: routeModel delegate: routeDelegate } Component { id: routeDelegate MapRoute { route: routeData line.color: "blue" line.width: 5 smooth: true opacity: 0.8 } } }
line group |
---|
line.color : color |
line.width : int |
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.
route : Route |
This property holds the route to be drawn which can be used to represent one geographical route.
