Ngl: Callback after worker finished

[harryjubb]

Hi again,

Is it possible to run code after an NGL.Worker has finished running?

The example I have in mind is for adding a surface representation. I would like to show a preloader until the surface appears, so that the user knows that something is happening.

I tried using, e.g.:

var structureName = 'structureName';

this.stage.getComponentsByName(structureName).list[0].signals.representationAdded.add( function(repr) {
  console.log('rep added.');
});

But it fires way before surface representations are generated.

All the best,

Harry

There is a general task counter available in the stage object.

stage.tasks.signals.countChanged.add(function(delta, count){
  // count is > 0 when the surface is still being calculated or a file is loaded
});

Thank you :)
