For this, you have to configure your Mapserver to respond to WFS:GetFeature requests. You can then use the WfsGetFeature widget. It will allow you to click and drag for selecting an area of interest, which will then immediately be issued as GetFeature request to your WFS. Note that this behavior of the WfsGetFeatureInfo is quite new, you need at least Mapbuilder 1.5alpha2 for this to work. > If not, how can a listen to events in order to query > the server after the region is selected? You could listen to the aoi event. But this is also fired every time the user zooms or pans on the map. So you would have to create a button control which registers the listener onSelect, and unregisters it onUnselect.
