identifyGraphicsOverlayCompleted is deprecated, what should I use?

FatmaAkdemir

I want to identify the clicked Graphic object on a MapGraphicsView. However the old method is deprecated, could you give me an example of the new method?

Hi @FatmaAkdemir. That signal goes along with the older and also deprecated

identifyGraphicsOverlay method (see here https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-geoview-obsolete.html#identifyGraphicsOverlay)

The replacement for all our deprecated TaskWatcher async methods are the newer QFuture versions, which do not require any signal to connect to.

https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-geoview.html#identifyGraphicsOverlayAsync (or its overload).

Here is a blog to covers porting from the older async patter to the newer one.

There are some examples in our samples repo that should help to get you started as well: https://github.com/search?q=repo%3AEsri%2Farcgis-maps-sdk-samples-qt+identifyGraphicsOverlayAsync&type=code

Thank you very much ! @JamesBallard1 Can I ask you one more question? We need something like a track trajectory, or track history, is there a feature or a class providing this?

You might benefit from checking out some of these samples:

https://github.com/Esri/arcgis-maps-sdk-samples-qt/tree/f4f5d85c8583a83e2067969dc39e1b255c2e0be9/CppSamples/Maps/ShowLocationHistory

They use things like simulated data sources and location tracking, which may be what you're looking for.
