Christian- If you are wanting to update the symbol of a particular graphic, can you just use updateGraphic that takes in the graphic's ID and the new symbol? ArcGIS Runtime SDK for Qt C++ API: EsriRuntimeQt::GraphicsLayer Class Reference Otherwise, you can create a new Graphic, and update the existing one with updateGraphic ArcGIS Runtime SDK for Qt C++ API: EsriRuntimeQt::GraphicsLayer Class Reference That would be the recommended approach. I would need to see your code to get a hint at why it might be crashing. -Luke ... View more

We plan to support shapefiles in our upcoming Quartz release, which is planned for later this year. -Luke ... View more

The Runtime's support for WMS layers at this release is very limited, and was initially included so that web maps that contained WMS layers could at least display them. Unfortunately, the class is not fully functional yet, but we do plan on having much better WMS support in Quartz. -Luke ... View more

Hmm, the image provider image should work with the image. Maybe you can try the legend sample that the AppStudio team has created: main.qml: Map {     id: map     anchors.fill: parent     extent: marylandExtent     ArcGISTiledMapServiceLayer {         url: "http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"     }     ArcGISDynamicMapServiceLayer {         id: dynamicService         //url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/MapServer"         //url: "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer"         //url: "https://gisapps.dnr.state.md.us/arcgis2/rest/services/AIMS/WaterAccess20140919/MapServer"         url: "https://gisapps.dnr.state.md.us/arcgis2/rest/services/Environment/Natural_Filters/MapServer"         onStatusChanged: {             if( status === Enums.MapStatusReady){                 mylegendView.updateModel();
