Subject: [OpenLayers-Users] Display Radius When Creating Circle with
DrawFeature

 

Using the following code,

 

      myLayer = new OpenLayers.Layer.Vector("My Layer");

      myCtrlCirc = new OpenLayers.Control.DrawFeature(

            myLayer,

            OpenLayers.Handler.RegularPolygon,

            {handlerOptions: {sides: 40}}

            );

 

I am creating a circle (40 sided polygon) by mousing down on the map,
dragging the mousing up. After mouseup, the polygon is added to the layer as
a vector feature. This allows me to see the size of the circle as I am
drawing it.

 

Is there a way to display the radius of the circle in a div as it is being
created? "sketchmodified" does not seem to get fired and I cannot think of a
way to get this to work.

 

Help greatly appreciated. Many thanks.

 

Regards,

 

Donald
