Re: [udig-devel] BBoxSelection Listener

[Aritz Dávila <aritz.davila@xxxxxxxx>]

Hi,

You have to create a layerListener:

		this.layerListener = new ILayerListener() {

			public void refresh(LayerEvent event) {

				updateLayerActions(event);
			}
		};

Then on refresh event, catch the event.

with  ILayer modifiedLayer = event.getSource(); 
you get the layer that throws the event, and with LayerEvent.EventType type = 
event.getType(); you should get the event type. Then on the case that the 
event is this type: FILTER, 
obtain the filter of the layer which is this : Filter newFilter = 
modifiedLayer.getFilter();

Cheers,
