Check if a polygon Graphic contains another Graphic

FatmaAkdemir — Mon, 05 Jul 2021 12:27:55 GMT

I have a region item consisting of 4 corners and a polygon constructed by those corners. I want to alert the user when another moving Graphic (simple one with a marker) enters into that polygon. How can I understand that my region contains a specific Graphic?

GeometryEngine::contains(const Esri::ArcGISRuntime::Geometry &geometry1, const Esri::ArcGISRuntime::Geometry &geometry2) seems to be the solution.

Hi Fatma,

Yes, that is the best way for now!

I would just like to say that we are working on a GeoTriggers feature which maps specifically to your use case (notifying when an area of interest is entered/exited). I can not commit to any specific release date, but you should keep an eye out for any announcements that mention GeoTriggers.
