Enable all layers for snapping

Vakhtang_Zubiashvili — Tue, 29 Oct 2024 06:27:47 GMT

Hi all,

In edit widget i want to enable all layers snapping, i used this code:

snappingOptions: { // autocasts to SnappingOptions() enabled: true, // global snapping is turned on // assigns a collection of FeatureSnappingLayerSource() and enables feature snapping on this layer featureSources: [{ layer: myFlLayer1, myflLayer2, enabled: true }] }

but, it des not work.

How can i pass several layers in featureSources?

Thanks

Hi @Vakhtang_Zubiashvili ,

You need to have a collection of FeatureSnappingLayerSource . So with three layers (the second one is not enabled) it might look something like this

featureSources: [{ layer: myFlLayer0, enabled: true }, { layer: myFlLayer1, enabled: false}, { layer: myFlLayer2, enabled: true }]

If you really want to enable snapping on all layers in your map you could probably do something like this but I haven't checked to see if this actually works. I think it should, but you might have to filter the allLayers collection first to just the layer types supported in featureSources

snappingOptions: { enabled: true, featureSources: map.allLayers }

Thank you @Sage_Wall , i see, i did not try to add FLs as objects and map.allLayers i couldn't think about it.

Thanks again
