详细描述

A Route type contains high level information about a route, such as the length the route, the estimated travel time for the route, and enough information to render a basic image of the route on a map.

The QGeoRoute object also contains a list of RouteSegment objects which describe subsections of the route in greater detail.

The primary means of acquiring Route objects is RouteModel.

Example

This example shows how to display a route's maneuvers in a ListView:

  import QtQuick 2.3
  import QtPositioning 5.5
  import QtLocation 5.6

  RouteModel {
      id: routeModel
      // model initialization
  }

  ListView {
      id: listview
      anchors.fill: parent
      spacing: 10
      model: routeModel.status == RouteModel.Ready ? routeModel.get(0).segments : null
      visible: model ? true : false
      delegate: Row {
          width: parent.width
          spacing: 10
          property bool hasManeuver : modelData.maneuver && modelData.maneuver.valid
          visible: hasManeuver
          Text { text: (1 + index) + "." }
          Text { text: hasManeuver ? modelData.maneuver.instructionText : "" }
      }
  }
