Add listeners to objects created by sketch

[Aeseir]

I am using Sketch widget to reduce overhead on some items and it mostly works (mostly).

This is how i set it up:

let sketch = new Sketch({
      availableCreateTools: ["point", "polyline", "polygon"],
      layer: this.graphicsLayer,
      view: this.view,
      creationMode: "single",
      defaultUpdateOptions: {
        enableRotation: false,
        enableScaling: false,
        enableZ: false,
        toggleToolOnClick: false,
      },
      visibleElements: {
        settingsMenu: false,
        selectionTools: {
          "lasso-selection": false,
          "rectangle-selection": false
        }
      }
    });

This results in me being able to create polygons which is great.

Question is how do i attach listeners to these shapes, so that on click it triggers a specific function/code?

I suspect the answer from @BenElan to the post 

“SketchViewModel methods turning off layerList toogle” in the Calcite Design System Questions

may help you

How does this help attach listeners to shapes created through Sketch widget?

Ok

I don´t know which function you are trying to trigger but in the example below, the output Sketch geometry is used as a parameter (sketchEvent.graphics[0].geometry) to a query..

          sketch.on("update", (sketchEvent) => {

                    const sketck_action_id = sketckEvent.action.id;

                    if (sketchEvent.state === "start") {

                        queryFeatureLayer(sketchEvent.graphics[0].geometry);

                    }

                    if (sketchEvent.state === "complete"){

                        graphicsLayer.remove(sketchEvent.graphics[0]);

                        if (sketchEvent.toolEventInfo && (sketchEvent.toolEventInfo.type === "scale-stop" || sketchEvent.toolEventInfo.type === "reshape-stop" || sketchEvent.toolEventInfo.type === "move-stop")) {

                            queryFeatureLayer(sketchEvent.graphics[0].geometry);

                        }

                    }

                });

Sorry i might not be clear with what i am trying to achieve.

Lets assume i have a bunch of graphics on the map, in this case they were added in by Sketch.

Is it possible to attach a listener to each graphic, so that when clicked on it alerts("hello world").

I am fairly new to ArcgJS and the documentation is not as clear as i am used to.

The MapView's hitTest method is what you're looking for, here is a sample.
