[OpenLayers-Users] double clicks on button control

[Dave Rafkind]

Hello list, anyone know how to get a Button control added to the map to 
consume and ignore double click events? I want to let the normal 
handling of double click events (ie the zooming) work if the user double 
clicks on the map normally. Also I would prefer not to have to patch 
OpenLayers if at all possible. Here's my code:

  var  extentControl =new  OpenLayers.Control.Button({
      displayClass:'olControlZoomToMaxExtent',
      title:"Zoom to extent of site",
      trigger:function  () {
          map.zoomToExtent(sitesLayer.getDataExtent());
      }
  });

  var  controls = [
      // other controls also added to this list
      
      extentControl
     
   ];

   var  panel =new  OpenLayers.Control.Panel({
       'displayClass':'olCustom',
       defaultControl: controls[0]
   });

panel.addControls(controls);
   map.addControl(panel);
