Re: [Dynapi-Widgetdev] Select list widget

[Richard B. <ma...@ri...>]

You can only alter the CSS properties once the layer has been written to the
document.
Maybe if you add them after this

  o.addChild(o.list)
  o.addChild(o.label)
  o.addChild(o.button)
  o.list.css etc...

it would work alright. - I assume o has been added to the doc at this point.
