pamela,
your getAlpha override idea works, but does not meet my needs. the
user needs to be able to modify the alpha of the layer dynamically
with a control. the getAlpha override only sets the alpha for the
layer once and cant be then modified.
my preferred solution is to use your original "addOverlay" idea so i
can direct control the foreground.alpha property. but i was unable to
make your example work.
i was able to add my custom TileLayer as overlay 1. that worked
fine. but when i added "MapType.HYBRID_MAP_TYPE.getTileLayers()
[1]" (the street layer) as a second overlay it failed to show up.
i think that the problem is with how i set up the MapType for the
map. here is my code. what am i doing wrong?
map.addMapType(MapType.SATELLITE_MAP_TYPE);
map.setMapType(MapType.SATELLITE_MAP_TYPE);
var customLayerOverlay:TileLayerOverlay = new TileLayerOverlay(new
CustomTileLayer());
var streetLayerOverlay:TileLayerOverlay = new TileLayerOverlay
(MapType.HYBRID_MAP_TYPE.getTileLayers()[1]);
map.addOverlay(customLayerOverlay);
map.addOverlay(streetLayerOverlay);
