QGC之PlanMapItems

PlanMapItems.qml中定义了变量object

Component{    id:missionLineViewComponent    MapPolyline{        line.width:3        line.color:"#be781c"        z:QGroundControl.ZOrderWaypointLines        path:object?[object.coordinate1,object.coordinate2]:undefined    property var object    }}

//planView.qml
当点击waypoint之后，就
_addWaypointOnClick=true
然后在

if(_addWaypointOnClick){    _insertSimpleMissionItem(coordinate,        _missionController.visualItems.count);}

object的产生

MapItems/PlanMapItems.qml
_missionLineViewComponent=missionLineViewComponent.createObject(map,{“object”,object})
