[OpenLayers-Users] custom function after dblclick

[Jachym Cepicky]

Hi,

I would like to call some function immediately, after the polygon is
digitized (user ends the digitization with dblclick and
OpenLayers.Handler.Polygon.dblclick(evt)  is called.

I did it like this:

/*
 * reinitialization of dblclick function
 */
OpenLayers.Handler.Polygon.prototype.dblclick = function(evt) {
        if(!this.freehandMode(evt)) {
            // remove the penultimate point
            var index = this.line.geometry.components.length - 2;

this.line.geometry.removeComponent(this.line.geometry.components[index]);
            this.finalize();
        }
        serialize("GeoRSS");
        return false;
    }

/*
 * Added editing toolbar
 */
editbar = new OpenLayers.Control.EditingToolbar(vlayer);
map.addControl(editbar);



/*
 * function for displaying digitized coordinates
 */

function serialize(type) {
            var xmls = new XMLSerializer();

            var serialize = new
OpenLayers.Format[type]({},map.layers[1]);
            var data = serialize.write(map.layers[1].features);
            alert(xmls.serializeToString(data));
}

Is there some better way, how to call some function, when digitizing is
done?

Thanks a lot

Jachym
