[OpenLayers-Users] mousewheel jumps two zoom levels

[Vidal, Antoni]

Hi list,

 

I've an OpenLayers.control.Navigation with following config options:

 

        var navControl = new OpenLayers.Control.Navigation({

            type: OpenLayers.Control.TYPE_TOGGLE,

            zoomWheelEnabled: true,

            mouseWheelOptions: {interval: 1}

        });

 

But when user changes map zoom level using mousewheel, map zoomlevel jumps from 0 to 2 and then to 4, etc.

 

Is possible to change this behaviour and force change zoomlevel one by one ?

 

Thanks in advance.
