Hi Paul, I believe you should be able to use the boundary method on GeometryEngine (GeometryEngine QML Type | ArcGIS for Developers) to obtain the polyline boundary of the Envelope. Then you can use the polyline to construct your Polygon. It might still be more efficient to construct the polygon directly from the xMin, xMax, yMin, yMax of the original envelope though. I hope that helps, Luke  ... View more

Hi George, are you running on linux? I think that "LINUX_PLATFORM_REPLACEMENT" may not be defined in your project if you are building with cmake. We set this in one of our .pri files which is used by qmake/qtcreator and I am not 100% sure that will be used by your cmake project.   It's probably worth adding some print statements so that you can confirm the import paths are correct (e.g. arcGISRuntimeImportPath and arcGISToolkitImportPath). You can also set the environment variable " QML_IMPORT_TRACE "  (see Import Statements | Qt QML 5.10 ) to try and debug what is going on.   I hope that helps, Luke ... View more

Hi Anat, I hope you are well. Unfortunately, we do not currently have a synchronous version of this call. One approach that might work for you is to create a QEventLoop which you can run to wait until the operation completes. I've included some code below that shows how that could work - any questions, let me know:         auto startTaskId = surface->locationToElevation(loc).taskId();         QEventLoop loop;         loop.connect(surface, &Surface::locationToElevationCompleted, this, [this, &loop, startTaskId](QUuid taskId, double elevation)         {             if (taskId != startTaskId)                 return;             qDebug() << elevation;             loop.quit();         });         loop.connect(surface, &Surface::errorOccurred, &loop, &QEventLoop::quit);         loop.exec(); ...

Hi Norbert, I hope you are well. I don't believe we do have an example of this workflow currently - but I will recommend we add one as it seems like a useful workflow to me. Here is some code I have put together to show how this could work. In this case I am creating a Surface and a single ArcGISTiledElevationSource. We have to manually load these since they are not added to the view in the same way we would for a 3D application. Once these are loaded, I am connecting to the mouseClicked signal on the MapView, obtaining a location for that click and starting the operation. I hope that helps, Luke     ArcGISTiledElevationSource* elevationSource = new ArcGISTiledElevationSource(                 QUrl(yourUrl), this);     connect(elevationSource, &ArcGISTiledElevationSource::errorOccurred, this, [](Error error)     {         qDebug() << error.message() << error.additionalMessage();     });     m_surface = new Surface(this);     m_surface->elevationSources()->append(elevationSource);     connect(m_surface, &Surface::errorOccurred, this, [](Error error)     {         qDebug() << error.message() << error.additionalMessage();     });     connect(m_surface, &Surface::loadStatusChanged, this, [](LoadStatus loadStatus)     {         qDebug() << "loadStatus:" << static_cast<int>(loadStatus);     });     connect(m_surface, &Surface::locationToElevationCompleted, this, [](QUuid, double elevation)     {       qDebug() << elevation;     });     connect(m_surface, &Surface::doneLoading, this, [this](Error error)     {         if (!error.isEmpty())             qDebug() << error.message() << error.additionalMessage();         qDebug() << "loaded";         connect(m_mapView, &MapGraphicsView::mouseClicked, this, [this](QMouseEvent& mouseEvent)         {             Point loc = m_mapView->screenToLocation(mouseEvent.x(), mouseEvent.y());             qDebug() << "locationToElevation: " << loc.toJson();             m_surface->locationToElevation(loc);         });     });     connect(elevationSource, &ArcGISTiledElevationSource::doneLoading, this, [this](Error error)     {         if (!error.isEmpty())             qDebug() << error.message() << error.additionalMessage();         qDebug() << "elevationSource loaded";         m_surface->load();     });     elevationSource->load(); ...

Hi there, You should be able to give the text symbol an offset using the "setOffsetX" or "setOffsetY" methods: MarkerSymbol Class | ArcGIS for Developers. They are defined on the base type MarkerSymbol rather than on TextSymbol  I hope that helps, Luke ... View more
