[OpenLayers-Users] OpenLayers.Class withOpenLayers.Control.GetFeature

[Arnd Wippermann]

try this:
...
opts.params.bbox = ...
return opts;
},
CLASS_NAME: "OpenLayers.myGetFeature"
});

It seems, that a class needs a CLASS_NAME.

Thanks for that Arnd, now it stops complaining about the missing "}", but
now it appears "TypeError: this.CLASS_NAME is undefined", what and where
should I put there?

Hi,
 
move 'return opts;' into the function body:
...
opts.params.bbox = ...
return opts;
}
 
to get rid of the error.

Hi all,

I'm wondering if someone could point me in the right direction to force the
BBOX of OpenLayers.Control.GetFeature to be always in long/lat coordinates.
I'm trying to get this with OpenLayers.Class, so the new control will
inherit OpenLayers.Control.GetFeature with just the small modification in
BBOX. This is what I've done:

OpenLayers.Control.myGetFeature =
OpenLayers.Class(OpenLayers.Control.GetFeature,{ 
            selectBox: function(position){ 
                var opts = OpenLayers.Control.GetFeature(position); 
                var baseSRSutm = this.map.getprojectionObject(); 
                var layerSRSdd = new OpenLayers.Projection('EPSG:4326'); 
                opts.params.bbox =
this.map.getExtent().transform(baseSRSutm,layerSRSdd).toBBOX(null,firstLayer
.reverseAxisOrder()); 
            }
            return opts; 
        }); 
 
but I'm getting that some "}" are missing. Is this the right way to use
OpenLayers.Class to do what I want?

Any help is much appreciated.

Gery
