GraphicsLayer addMany finish rendering

RodrigoFelga — Thu, 14 Sep 2017 18:06:55 GMT

I have a array of graphics that I'm adding to a GraphicsLayer with the following code:

gLayer.addMany(features);

This works correctly but I need to catch when then graphics finished rendering on the map because many times the array has many graphics and I need to show a loading to the user.

Thanks

Rodrigo,

You just need to watch the layer view updating property for false.

view.whenLayerView(gLayer).then(layerView => {
    watchUtils.whenFalse(layerView, 'updating', () => {
        console.log('The layer is now rendered');
    });
});‍‍‍‍‍

Thanks for your reply. I did that but it triggers before the graphics appears on the screen.

Rodrigo,

That is strange the updating property is suppose to be the property to watch. I have used it and it worked fine on my end. Maybe you can just add a settimeout inside the result function for a couple hundred milliseconds.
