How to implement draw functionality of polylines/polygons in ArcGIS SDK 100.0

DarkRider

In ArcGIS 10.2.6 there was sample code about drawing polylines. I am now using the ArcGIS 100.0 SDK trying to implment the same functionality there but it does not work somehow. Nothing is shown on the map.

This is the code I am currently using:

When clicking left on the map, this code is executed:

if(!m_currentPolylineStarted)

        {

            m_currentPolyLineBuilder.addPoint(mapPointMouse);
            m_currentPolylineGraphic = new Esri::ArcGISRuntime::Graphic(m_currentPolyLineBuilder.toGeometry(), this);            
            m_graphicsLayer->graphics()->append(m_currentPolylineGraphic);
            m_currentPolylineStarted = true;
//            m_currentPolyline.startPath(mapPointMouse);
//            m_currentPolyline.lineTo(mapPointMouse);
//            Esri::ArcGISRuntime::Graphic* graphic = new Esri::ArcGISRuntime::Graphic(Esri::ArcGISRuntime::Polyline(m_currentPolyline), Esri::ArcGISRuntime::SimpleLineSymbol(Qt::red, 1));
//            m_currentPolylineId = m_graphicsLayer->graphics()->append(graphic);
 }

        else

        {

            m_currentPolyLineBuilder.addPoint(mapPointMouse);

            m_currentPolylineGraphic->setGeometry(m_currentPolyLineBuilder.toGeometry());
//            m_currentPolyline.lineTo(mapPointMouse);
//            m_graphicsLayer->updateGraphic(m_currentPolylineId, new Esri::ArcGISRuntime::Graphic(Esri::ArcGISRuntime::Polyline(m_currentPolyline), Esri::ArcGISRuntime::SimpleLineSymbol(Qt::red, 1)));
        }

where mapPointMouse is the current mouse point position. The commented code was the old way (using ArcGIS SDK 10.2.6 which worked fine.

What am I doing wrong?

Are there samples providing the same functionality on the new ArcGIS SDK 100.0?

Thanks in advance

Hi Luke,

I've added a simpleLineSymbol, but I also find out that my mapPointMouse was in the wrong spatial reference system. My Polylinebuilder is using spatialReference WGS84 while my mapPointMouse is not georeferenced. When I put in the right coordinate values, it works! 

            m_currentPolyLineBuilder.addPoint(mapPointMouse);

            Esri::ArcGISRuntime::SimpleLineSymbol simpleLineSymbol;

            simpleLineSymbol.setColor(Qt::red);

            simpleLineSymbol.setWidth(2);

            simpleLineSymbol.setStyle(Esri::ArcGISRuntime::SimpleLineSymbolStyle::Solid);

            m_currentPolylineGraphic = new Esri::ArcGISRuntime::Graphic(m_currentPolyLineBuilder.toGeometry(), &simpleLineSymbol);

            m_graphicsLayer->graphics()->append(m_currentPolylineGraphic);

            m_currentPolylineStarted = true;

Thank you!
