[OpenLayers-Users] adding custom controls to layer switcher?

[Franz Buchinger]

Hi Imran,

if you want to extent the layer switcher with custom functionality, the
cleanest way is to derive your own CustomLayerSwitcher class from
Control.LayerSwitcher.

You just need to redefine the redraw() method, where all the HTML of the
Control is assembled.

OpenLayers.Control.MyCustomLayerSwitcher =
OpenLayers.Class(OpenLayers.Control.LayerSwitcher,{
    redraw: function (){
       //copy this method from lib/openlayers/control/layerswitcher.js and
change it to your needs

    },
   CLASSNAME: "OpenLayers.Control.MyCustomLayerSwitcher"
});

you would then use your layerswitcher like so:

mylayerswitcher = new OpenLayers.Control.MyCustomLayerSwitcher();
mymap.addControl(mylayerswitcher);

kind regards,

Franz
