Subject Re: [FlexJS] HTMLElementWrapper extending Sprite
Date Fri, 29 Jul 2016 06:00:13 GMT

I’m not totally getting the use case of the IFlexJSElement, but there’s definitely nothing
wrong with adding a wrapper class that extends a Flash type.

I’d think it should extend DisplayObject rather than InteractiveObject though.
