[Mapserver-users] Mapserver and flash

[Geoffrey Rowland]

Okay, Thanks, I have made the function ElementSelected and can get the 
LayerID,ShapeID, and Event.

But I'm still at a loss how to get the SWFDUMPATTRIBUTES then?  lets say 
my attribute is called Name.  how do I get the value using ActionScript?

Here is what I have so far (just doing this as a test)

onClipEvent (load) {
        loadMovieNum("state_layer_0.swf",1);
}   
onClipEvent(mouseDown) {
    _level1.ElementSelected = function(lid,sid,ev){
             trace("The Layer id is : " + lid);
             trace("The Shape id is : " + sid);
             trace("The event was : " + ev);
    
}
        _level1.ElementSelected(LayerId,ShapeId,Event, Name)
}

Thanks,
Geoff
