QML MapPolyline Element

These properties hold the width and color used to draw the border of the circle.

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.

This documentation was introduced in Qt Mobility Mobility 1.2.

This property holds the ordered list of coordinates which define the polyline.

This documentation was introduced in Qt Mobility Mobility 1.2.

This property holds a boolean corresponding to whether or not the polyline is visible.

This documentation was introduced in Qt Mobility Mobility 1.2.

This property holds the z-value of the polyline.

Map objects are drawn in z-value order, and objects with the same z-value will be drawn in insertion order.

Adds coordinate to the path. The resulting path is derived from values at the time of assignment, meaning that later changes in values are not reflected in the path.

A basic example is to draw the path where one has been:

 PositionSource {
     id: myPositionSource
     active: true
     nmeaSource: "nmealog.txt"
     updateInterval: 2000
     onPositionChanged: {
         console.log("Position changed in PositionSource")
         myPathPolyline.addCoordinate(position.coordinate)
     }
 }

See also removeCoordinate.

Remove coordinate from the path. If there are multiple instances of the same coordinate, the one added last is removed. Removed Coordinate is not deleted.

 onButton2Clicked: {
     polyline.removeCoordinate(map.center)
 }

If more finetuned control is needed, one can also iterate and/or use the inherent index property of the path list.

 onButton1Clicked: {
     for (var index = 0; index < polyline.path.length; index++)  {
         console.log("Index, latitude:" + index + " , " + polyline.path[index].latitude);
     }
     polyline.removeCoordinate(polyline.path[2])
 }
