So how would I apply that expression to a polyline that has varying heights along it? (edit: like a flight path) I am not encoding the height as a value in the feature or graphic since it changes, I am putting them into the z axis of the point coordinates I put into a polylineBuilder.

I found this article, https://desktop.arcgis.com/en/arcmap/latest/extensions/arcscene/vertical-exaggeration-and-z-unit-conversion-of-layers-in-arcscene.htm , describing that what I want was possible for older arcmap/arcscene

I have a graphic in a sceneview and I want to be able to exaggerate the terrain and the relative height of the graphics. I see in https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-layersceneproperties.html#altitudeOffset the altitude offset but that only seems to add to the height of the graphic, it is not a multiplier. Is there a different function I should be using for that?

I think that is what I am going to end up doing, have the icon png files downloaded local and have a sed script do a search and replace of the web addresses with local paths, then have the map load in the modified kml file.

Adding more onto this, when I traverse the kml nodes, the "foo Points" folder node, its style ends up being a nullptr when the kml is loaded. When I traverse to the placemark node I can see that for the placemark the style is iconStyle but changing the url for the icon does not seem to affect the drawing of the symbol.

So a coworker gave me a kml file to display in my disconnected system and that kml file refers to symbols from web icons. So I modified the sample from https://github.com/Esri/arcgis-runtime-samples-qt/tree/main/ArcGISRuntimeSDKQt_CppSamples/Layers/DisplayKml and put the kml as the local file to load. In my disconnected system the icon does not end up being correct, just a red X. I know that the symbols used will be fairly limited and I should be able to pre-cache them somewhere in my system. Is there a way to have some sort of configuration mapping saying that if it is looking for a certain weburl to actually load a certain local file? This is on Runtime Qt 100.14, sample picture: simplified kml snippet: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2"> <Document> <name>foo</name> <Folder> <name>foo Points</name> <Style id="fooPoint"> <IconStyle> <scale>0.5</scale> <Icon> <href>https://maps.gstatic.com/intl/en_us/mapfiles/markers2/measle_blue.png</href> </Icon> <hotspot x=".5" xunits="fraction" y=".5" yunits="fraction"/> </IconStyle> </Style> <Placemark> <name>Foo</name> <description><![CDATA[<h1>Hello Esri!</h1>]]></description> <TimeStamp> <when>1980-01-01T00:01:01Z</when> </TimeStamp> <styleUrl>#fooPoint</styleUrl> <Point> <coordinates>-70.000000,30.0000000,0.00000000</coordinates> <altitudeMode>absolute</altitudeMode> </Point> </Placemark> </Folder> </Document> </kml>

I dont do QML but with function geoElementsCountFromResult(identifyLayerResult) Isnt "identifyLayerResult" a claimed variable name at the global scope? Maybe refactor that to something more unique and see if the behavior persists?

‎06-27-2022

What you probably want is setViewpointGeometry https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-mapview.html#setViewpointGeometry-1 something like: m_mapView->setViewpointGeometry(polyline_builder->extent());

This suggestion was derived from showing some visualizing dted stuff to coworkers and one person threw that idea out there so I did some research. If I was going to rank wish list items in the runtime raster functionality area I would have : adding the contour raster function as a simple to use raster renderer, where I can change the interval without recreating the object being able to make custom color ramps that feature transparency being able to play with raster function settings in Pro, then having an option to export the settings as json for use in a runtime raster function(This may already be possible but I dont know how to do it, get the guy that does the youtube one minute map hacks to do a demo if it is possible https://www.esri.com/arcgis-blog/author/j_nelson/ ) explain why when I am using a min/max stretch renderer on elevation that goes negative (Salton Sea/death valley) and I set my minimum value to -100 I get a ring of blue color around the edge of the depressed area with stuff below negative100 colored according to the color map, if I set it to 0 everything negative is blue, If I set the minimum to positive 500 everything below positive 500 is colored blue. this raster function mask included ranges question.

Darn, is that on your backlog or is it a "wont fix"?

https://developers.arcgis.com/qt/layers/add-raster-data/#raster-functions-supported-by-arcgis-runtime https://pro.arcgis.com/en/pro-app/latest/help/analysis/raster-functions/mask-function.htm Looking at the documentation for raster functions supported by Qt and for the mask raster function in pro, there is an included ranges parameter in pro that seems to be missing in runtime qt. Ideally as a developer I want to give my users the ability to set a minimum value that they can ignore and display it as transparent on the map.

That seems like it works but it breaks another workaround we have. We used the QGraphicsItem's mouse moved signal and if it was a left click and drag would use that to query the items drawn on the map, and if it was a middle mouse click and drag we would take the event and change the button and pass that on to QGraphicsItem::mouseMoveEvent so the runtime Qt would see it as a drag operation and pan the map around. Do you know of a way to re-map those buttons, either as a setting for just the esri software or to do it every time in the mouse moved signal?

‎04-19-2022

From looking at the runtime Java's API their mouse moved signal is a hover move and mouse dragged is for when the user click and dragged the mouse on the map. Why doesn't the runtime Qt have the same sort of setup for connecting to a signal for hover move events? I currently have a workaround by creating a class inheriting QGraphicsItem and calling setAcceptHoverEvents on it. However I have reports from our users that sometimes the QGraphicsItem class sometimes stops receiving any mouse events at all until the window is resized.

dead link, and judging by his username he retired 😞

To answer my own question, I just found out that the events website is saying that FedGIS 2022 is cancelled and that a livestream event is happening later in the month. https://www.esri.com/en-us/about/events/federal-gis-conference/save-date
