Hi Don (and thanks for your hint!!), there's only a problem. The layers are quite big and the "pan" option is slow. Do you think using this functions makes the "pan" faster?

Thanks!!!

Hi Saglietti,

You can call:

((LayerHandler)mapHandler.getClass
(com.bbn.openmap.LayerHandler)).turnLayerOn(visibleFlag,
shapeLayerEdifici);

where visibleFlag is a boolean for whether you want the layer to be
on (true) or off (false).

Hope this helps,

- Don
