Event 'when markers of GeoJSON are loaded'

[eljazouli]

Hi everyone,
first of all, thank you for this great directive !

I am trying to capture the event when markers are loaded and added to the map to hide a spinner. I'm using the markers directive to display a GeoJSON object.
Now i simply add the GeoJSON to the scope markers like this :
$scope.markers = geojson;
I'm thinking of using promises (http://angular-ui.github.io/angular-google-maps/#!/api/Promise) but i need your help.

Thanks in advance !

Does the spinner have to end after it is loaded by the UI or can it just stop spinning when you're done loading it via $http?

[eljazouli]

Actually the GeoJSON object is loaded in another state and stored in a service so the spinner has to end after it is loaded by the UI (when the markers are displayed on the map)

Well this callback and or promise will have to be added to the code base as I do not see how else you can do it currently.

You could maybe hook to map 'idle' event and only register to it prior to updating markers. Then on idle you know it is drawn (then deregister). But that is probably an unreliable hack.

Even if it is stored in a service you can still return a promise from that service. Or pass events via $rootScope broadcast or emit.

The promise that fetch the geojson is resolved in the other state and stored in a service so the array of markers is available instantly but I think that $scope.markers = geojson takes some time before the markers are rendered in the map.

Thanks for the tip about the 'idle' event, It might resolve the problem.

Cool hope it works; otherwise I can direct you to where callbacks need to be added in markers, and marker.

[eljazouli]

Yes please, it would be better to do it the right way

Why not just hook your spinner to $http calls? Thats what some do.
