Measurement vertex update event not working

nidaaktan — Thu, 20 May 2021 12:18:10 GMT

Hi,

I can catch the vertex-add event like this but vertex-update event not working.I can't run the function that i set vertex-update event.

measurement.watch('viewModel.state', async (state) => {

if (state === 'ready' || state === 'measuring') {

measurement.activeWidget.viewModel.tool._draw.activeAction.on('vertex-update', updateGraphic);

measurement.activeWidget.viewModel.tool._draw.activeAction.on('vertex-add', addGraphic);

}

});

Does anyone know how i can do it?

Thanks

Hi @nidaaktan, overall, what are you trying to accomplish? I would not recommend using undocumented or private properties as they are not supported and could change anytime.

I try to change vertex according to the coordinates i have created when measurement update is active but measure widget doesn't have events like 'measure-update'.

How can i do it?

Thanks

Ok, this sounds like a snapping scenario. Are you trying to update the vertex coordinates to a specific feature? If so, we are working on this functionality for a future release. It's also worth noting that for very precise measurements, the GeometryEngine would be a good choice.

Yes it is snap scenario, thanks for reply. I'll research how to use the GeometryEngine.
