Re: [OpenLayers-Users] Get the center of a regular Polygon

[Alexandre Dube]

Hi,

Using Firebug, try putting a breakpoint on your first line of you 
"added" function. You'll see that the "feature" argument is not a 
feature, but rather an event containing your feature. Try :

added = function (event) {
    var feature = event.feature;
    var center=feature.geometry.getCentroid();
    alert(center.x);
};


Regards,

Alexandre

Hello,
i try to get the center of a just drawn regular Polygon with the follwing
code:

  added =function (feature)
             {

               var center=feature.geometry.getCentroid();

               alert(center.x);
             };

             controls = {
                 regular: new OpenLayers.Control.DrawFeature(vectors,
                             OpenLayers.Handler.RegularPolygon,

{eventListeners:{"featureadded":added},handlerOptions: {sides: 40}}),
                 drag: new OpenLayers.Control.DragFeature(vectors)
             };


but the alert doesnt activate so there is a error. I think the argument
"feature" has not the type OpenLayers. Feature, but i cant find what exact
type feature has.

Is there perhaps a different way to get the center of the regular polygon?
Thanks a lot.
Marc
